Embedded Resource Manager (ERM)

The Embedded Resource Manager (ERM) feature allows you to monitor internal system resource utilization for specific resources such as the buffer, memory, and CPU. ERM monitors resource utilization from the perspective of various subsystems within the Cisco IOS software such as resource owners (ROs) and resource users (RUs). ERM allows you to configure threshold values for system resources.

The ERM infrastructure is designed to allow for granular monitoring on a task basis within the Cisco IOS software. Network administrators can define thresholds to create notifications according to the real-time resource consumption. ERM goes beyond simply monitoring for total CPU utilization. Through the use of ERM, network administrators and operators can gain a better understanding of the device’s operational characteristics, leading to better insight into system scalability and improved system availability.

Information About Embedded Resource Manager

ERM promotes resource availability by providing the infrastructure to track resource usage.

To configure threshold values for resource manager entities, you should understand the following concepts:

Benefits of the Embedded Resource Manager

The ERM framework tracks resource utilization and resource depletion by monitoring finite resources. Support for monitoring CPU, buffer, and memory utilization at a global or IOS-process level is available.

The ERM framework provides a mechanism to send notifications whenever the specified threshold values are exceeded by any resource user. This notification helps network administrators diagnose any CPU, buffer, and memory utilization issues.

The ERM architecture is illustrated in the figure below.

ERM provides a framework for monitoring any finite resource within the Cisco IOS software and provides information that a user can analyze to better understand how network changes might impact system operation. ERM helps in addressing infrastructure problems such as reloads, memory allocation failure, and high CPU utilization by performing the following functions:

Monitoring system resource usage.
Setting the resource threshold at a granular level.
Generating alerts when resource utilization reaches the specified level.
Generating internal events using the Cisco IOS Embedded Event Manager feature.

Resource Accounting and Thresholds Tracking in ERM

ERM tracks the resource usage for each RU internally. An RU is a subsystem or process task within the Cisco IOS software; for example, the Open Shortest Path First (OSPF) hello process is a resource user. Threshold limits are used to notify network operators of specific conditions. The ERM infrastructure provides a means to notify the internal RU subsystem of threshold indications as well. The resource accounting is performed by individual ROs. ROs are part of the Cisco IOS software and are responsible for monitoring certain resources such as the memory, CPU, and buffer. When the utilization for each RU exceeds the threshold value you have set, the ROs send internal notifications to the RUs and to network administrators in the form of system logging (syslog) messages or Simple Network Management Protocol (SNMP) alerts.

You can set rising and falling values for critical, major, and minor levels of thresholds. When the resource utilization exceeds the rising threshold level, an Up notification is sent. When the resource utilization falls below the falling threshold level, a Down notification is sent.

ERM provides for three types of thresholds to be defined:

The System Global Threshold is the point when the entire resource reaches a specified value. A notification is sent to all RUs once the threshold is exceeded.
The User Local Threshold is the point when a specified RUs utilization exceeds the configured limit.
The User Global Threshold is the point when the entire resource reaches a configured value. A notification is sent to the specified RU once the threshold is exceeded.

System Resources Monitored by the Embedded Resource Manager

ERM monitors CPU, buffer, and memory utilization at a global and task-based level. To avoid infrastructure issues and promote the availability of system resources, the resource owners described in the following sections are monitored:

CPU Resource Owner

The ERM feature uses the existing loadometer process to calculate the load information displayed by the show processes cpu command. This method generates a report of the extended load statistics and adds it to a circular buffer every five seconds. You can obtain a record of the load statistics for the past one minute through the CLI. This feature also provides an intelligent CPUHOG profiling mechanism that helps to reduce the time required to diagnose error conditions.

The functions described in the following sections help in load monitoring.

Loadometer Process

The loadometer process generates an extended load monitor report every five seconds. The loadometer function, which calculates process CPU usage percentage, is enhanced to generate the loadometer process reports.

Scheduler

The scheduler collects data when a process is executed, which enables the loadometer to generate reports. The scheduler collects data when the process is launched or when the process transfers control to the scheduler.

Snapshot Management Using Event Trace

Snapshot management manages the buffer in which snapshots of reports are stored. The snapshot management infrastructure stores, displays, and releases the snapshots.

Automatic CPUHOG Profiling

The timer Interrupt Service Routine (ISR) provides automatic CPUHOG profiling. The timer ISR begins profiling a process when it notices that the process has exceeded the configured value or a default of twice the maximum scheduling quantum (maximum time taken for the execution of a task).

On beginning the profiling, the timer ISR saves the interrupted program counter (pc) and return address (ra) in a preallocated buffer. This process provides information that can help the user analyze the CPUHOG.

The profiling continues until the CPUHOG is reported or the buffer is full. To analyze the computation of a long running process you must specify a process ID (PID) and a threshold to start the profiling. When this process takes up more than the specified time (in milliseconds), the profiling begins.

When the data belonging to a particular process exceeds the default size of the buffer, it is reported as a CPUHOG. The default size of the buffer is 1250 entries and can store up to five seconds of profiling data.

Memory Resource Owner

The Embedded Resource Manager feature enhances the memory manager in Cisco IOS devices. The enhancements are described in the following sections:

Memory Usage History

The Embedded Resource Manager feature helps in maintaining memory fragmentation information and thus reduces the need for maintenance of separate scripts for collecting such information.

Memory Accounting

ERM performs the accounting of information for memory by tracking the memory usage of individual RUs. When a process is created, a corresponding RU is also created, against which the usage of memory is recorded. The process of RU creation helps the user to migrate from a process-based accounting to a resource user-based accounting scheme for memory.

The memory RO maintains a global threshold and a per-RU memory usage threshold that can be configured through the ERM infrastructure. The memory RO also tracks the global free memory. When a particular RU’s memory usage exceeds the global free memory, a notification is sent to the registered resource monitors (RMs). Similarly when a particular RU exceeds its threshold of memory usage, a notification is sent to that RU. These notifications are sent using the ERM infrastructure.

A memory RO has the intelligence to assign memory to a RU. When a memory RO receives an allocation request, the memory is assigned to the current RU. When a free request is received, the memory RO reduces the memory assigned to the RU.

Interface Wedging and Packet Memory Leaks

In certain situations, errors in the system accounting of incoming packets can occur, leading to a “memory leak” caused by the input queue. When there is a leak in an interface’s input queue, gradually the queue reaches its maximum permitted value, causing the interface to become “wedged.” A wedged interface may no longer process incoming packets. Packet memory leaks can cause interface input queue wedges.

The Packet Memory Reclamation functionality improves the infrastructure for preventing wedged interface input queues, and it provides a method for changing the defaults of that infrastructure. The Embedded Resource Manager provides the Packet Memory Reclamation functionality for “unwedging” interface input queues and configuring the system to detect and rectify packet leaks.

Note

To use the Packet Memory Reclamation functionality, you must be running Cisco IOS Release 12.4(6)T or a later release. Additional troubleshooting (debugging) commands were introduced by this enhancement for use by technical support representatives in specific situations.

Memory Resource Reclamation for Interfaces

The Garbage Detection process works in conjunction with the Memory RO in achieving interface unwedging (for more details, see the Memory Leak Dectector fe ature guide that is part of the Cisco IOS Configuration Fundamentals Configuration Guide ).

As part of the reclamation process, incoming packets that belong to a leaked input queue can be deallocated and reused. This feature provides a command (critical rising ) that can be used to fine-tune memory resource reclamation.

Note

Configuration of this feature will typically be needed only as part of a troubleshooting process with a Cisco Technical Support representative. Additional configuration tasks or special technical support commands may be required before this feature can be effectively used. Additional memory debug leak internal service commands are made available to Cisco Technical Support engineers for use in specific situations.

The deallocation procedure is triggered when a check is made to see if packets are using too much memory. Thresholds for the memory RO can be configured using a global policy of any level.

The purpose of configuring this memory policy is to find a balance between the utilization of the Memory Leak Detector (that can become resource intensive) and the need to detect packet memory leaks. Ideally, the system should perform deallocation only when it becomes absolutely necessary.

The critical rising command allows you to set a rising and falling threshold percentage for critical levels of I/O memory usage, and to specify an interval for those values. These values trigger the Memory Leak Detector process and, if needed, the deallocation procedure.

For example, if memory usage is more than that of the rising threshold of 75 percent of total I/O memory for more than 5 seconds, the “critical” notification is generated within the system and a callback is issued. As an action in the callback, a check is made to see if the packets are using too much memory. When the packets have used too much memory, the deallocation procedure begins. If the deallocation procedure does not bring memory utilization below the lower threshold value, the deallocation procedure is periodically reattempted. Once the memory usage falls below the configured threshold value, the periodic attempts to deallocate are stopped.

Memory Leak Reclamation

The Packet Memory Reclamation feature uses the ERM infrastructure to clean up and reclaim leaked Cisco IOS packet memory.

This feature uses the Memory Leak Detector process (sometimes referred to as the Garbage Detection or GD process) and the memory-manager RO functionality to reclaim packet memory.

I O Memory

The I/O memory pool is one of the memory types in Cisco IOS software. The input queue buffers use memory from this pool for processing.

Buffer Resource Owner

The Embedded Resource Manager feature addresses the recurring problems of the Buffer Manager described in the following sections.

Automatic Buffer Tuning

The Embedded Resource Manager feature allows you to automatically tune the buffers using the buffer tune automatic command. The buffer RO tunes permanent memory in particle pools based on the usage of the buffer pool.

The buffer RO tracks the number of failures and the availability of memory in the buffer pool. When the number of failures increases above 1 percent of the buffer hits or when no memory is available in the buffer pool, the buffer RO performs an automatic tuning.

Note

Ensure that there is sufficient free I/O memory or main memory using the first lines of the show memory command output before enabling automatic tuning of buffers.

Here are some keywords from the buffer tune command that can help you verify if you have sufficient I/O memory:

permanent : take the number of total buffers in a pool and add 20 percent.
min-free : set the min-free keyword to 20 to 30 percent of the permanent number of allocated buffers in the pool.
max-free : set the max-free keyword to a value greater than the sum of permanent and minimum values.

However, when there is a traffic burst, the Cisco IOS device may not have enough time to create the new buffers and the number of failures may continue to increase.

The Embedded Resource Manager feature monitors the buffer pool every minute for tuning (that is, for number of hits, number of failures, and the number of counters created). When buffer tuning is enabled, the buffer RO automatically tunes the buffers when required.

Buffer Leak Detection

The Embedded Resource Manager feature allows Cisco IOS devices to detect and diagnose potential buffer leaks. All the buffers in a pool are linked so that they can be traced easily. The number of buffers allocated for incoming and outgoing packets in each buffer pool is tracked and can be displayed in the show buffers leak command output.

Buffer Accounting

The Embedded Resource Manager feature consists of mechanisms to account for the usage of buffers. All buffers are owned by the pool manager process (buffer RU). When a RU requests a buffer, the allocated buffer is allotted to that RU. When the RU returns the buffer, it is deducted from the RU’s account. The packet type from the output of the show buffers usage command indicates the RU to which the packet belongs.

Buffer Usage Thresholding

The Embedded Resource Manager feature provides a facility to manage high buffer utilization. The buffer manager RO registers as a RU with the memory RO. The buffer manager RU is set before a memory allocation is made for creating new buffers. The buffer manager also registers as an RO. When a buffer is allocated, the current RU (if any) is charged with the memory allocation. The buffer manager RO registers for the notifications from the memory manager for the processor and I/O memory pool. If the I/O memory pool is falling short of memory, the buffer manager tries to free the lists of all the buffer pools. If your Cisco IOS device does not support I/O memory, then it registers for notifications from the processor memory.

Cisco IOS software maintains a threshold per buffer pool. When a particular pool exceeds the specified threshold, ERM sends a notification to all the RUs in that pool, so that the RUs can take corrective measures. Thresholds are configured for public buffer pools only.

Global notification is set for every pool in the system; that is, one notification for all pools in the public pool and one notification for each pool in the private pool. Threshold notifications are sent to only those RUs that have registered with the ROs for getting notifications. A list of RUs that have registered with the RO is maintained by the RO. When the threshold of a particular RU is exceeded, then that RU is notified and marked notified. When the buffers are recovered, the notified RUs are moved back to the original list.

For example, an Ethernet driver RU is allocated buffers from some particular private pool. Another RU, Inter Processor Communication (IPC), is added to the list. In this case, when the pool runs low on buffers, the IPC RU gets a notification and it can take corrective measures.

You can configure threshold values as percentages of the total buffers available in the public pool. Total buffer is the sum of maximum allowed buffers and the permanent pools in the public buffer pool. If these values change due to buffer tuning, then the threshold values also change. For example, if the configuration requires that a notification be sent when the IPC RU is holding more than 40 percent of Ethernet buffers and the sum of permanent and maximum allowed for Ethernet buffers is 150 percent, then the Ethernet pool is notified when the IPC RU is holding 60 percent.

Resource Policy Templates

Resource owner policy is a template used by the ROs to associate a RU with a set of thresholds that are configured through the CLI. This template can be used to specify system global, user local, and per user global thresholds. A particular resource group or RU can have only one policy associated with it. The policy template for ROs is maintained by the ERM framework.

When a policy template is associated with a user type and its instance (RUs), the thresholds configured in that policy are applied based on the RU to RO relationship. This method ignores any RO configuration that may not be applicable to the RU.

Applying a Policy to Resource Users

Perform this task to apply a policy or policy template to RUs or resource groups.

SUMMARY STEPS

enable
configure terminal
resource policy
policy policy-name [global | type resource-user-type ]
exit
user {resource-instance-name resource-user-type resource-policy-name | global global-policy-name | group resource-group-name type resource-user-type }
instance instance-name
policy policy-name

DETAILED STEPS

Command or Action Purpose

Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2

configure terminal

Example:


Router# configure terminal

Enters global configuration mode.

Step 3

resource policy

Example:


Router(config)# resource policy

Enters ERM configuration mode.

Step 4

policy policy-name [global | type resource-user-type ]

Example:


Router(config-erm)# policy policy1 type iosprocess

Configures a resource policy and enters ERM policy configuration mode.

The policy-name argument identifies the name of the resource policy.
The global keyword is used when you are configuring a system global policy.
The type keyword indicates that you are configuring either a user local or per user global policy. The resource-user-type argument identifies the name of the resource user type you want to attach the policy to.

Step 5

exit

Example:


Router(config-erm)# exit

Exits ERM policy configuration mode.

Step 6

user {resource-instance-name resource-user-type resource-policy-name | global global-policy-name | group resource-group-name type resource-user-type }

Example:


Router(config-erm)# user group lowPrioUsers type iosprocess

Example:

Applies a policy system wide (global thresholding), a group of users (group thresholding), or a particular user.

Note

When you apply a group policy to a group of RUs by giving the group keyword in this command, the Cisco IOS router enters the resource group configuration mode. Go to Step 7 if you want to add RUs to the resource group. Got to Step 8 if you want to apply a policy to the resource group.

The resource-instance-name argument identifies the name of the RU to which you are applying a policy.
The resource-user-type-name argument identifies the type of RU.
The resource-policy-name argument identifies the name resource policy you are applying to the individual RU.
The global-policy-name argument identifies the name of the global policy you are trying to apply.
The resource-group-name argument identifies the name of the resource group.

Step 7

instance instance-name

Example:


Router(config-res-group)# instance http

Adds an RU to a resource group. The instance-name argument specifies the RU or instance name.

Note

All the RUs added by this command will be grouped together under the resource group and the same thresholding policy will be applied to all the RUs. For example, if you have created a resource group lowPrioUsers in Step 6, then all the RUs you add in Step 7 will be part of the resource group lowPrioUsers and the same policy is applied to all the RUs.

Step 8

policy policy-name

Example:


Router(config-res-group)# policy group-policy1

Specifies the policy you want to apply to the resource group you created in Step 6. The policy-name argument specifies the name of the group policy.

This command helps you to set the same threshold policy to a group of RUs grouped under a resource group. For example, if you have some low-priority tasks or RUs like http and snmp and you want to set a threshold not on these individual RUs, but as a group; then add these RUs to the lowPrioUsers group using Step 7 and then apply a threshold policy using Step 8. In this case, if you have set a minor rising threshold of 10 percent (this 10 percent threshold is applied to both http and snmp in the lowPrioUsers group), then a notification is sent to lowPrioUsers resource group when the accumulated usage exceeds the 10 percent mark. That is, if http uses 4 percent and snmp uses 7 percent, a notification will be sent to all the RUs in the lowPrioUsers resource group.

Setting a Critical Rising Threshold for Global I O Memory

Perform this task to specify a critical rising threshold value for the global I/O memory pool. If global I/O memory resource consumption meets or exceeds this value, the Memory Leak Detector process will be automatically triggered. This configuration is only needed if you are experiencing a problem and you want to change (fine tune) how often the automatic process occurs (for example, set the threshold lower so that deallocation check occurs more frequently).

SUMMARY STEPS

enable
configure terminal
resource policy
policy policy-name [global | type resource-user-type ]
Do one of the following:

system
slot slot-number

memory io
critical rising rising-threshold-value [interval interval-value ] [falling falling-threshold-value [interval interval-value ]] [global ]
exit

DETAILED STEPS

Command or Action Purpose

Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2

configure terminal

Example:


Router# configure terminal

Enters global configuration mode.

Step 3

resource policy

Example:


Router(config)# resource policy

Enters ERM configuration mode.

Step 4

policy policy-name [global | type resource-user-type ]

Example:


Router(config-erm)# policy policy1 type iosprocess

Configures a resource policy and enters ERM policy configuration mode.

The policy-name argument identifies the name of the resource policy.
The global keyword is used when you are configuring a system global policy.
The type keyword indicates that you are configuring either a user local or per-user global policy. The resource-user-type argument identifies the name of the resource user type you want to attach the policy to.

Step 5

Do one of the following:

system
slot slot-number

Example:


Router(config-erm-policy)# system

Example:


Router(config-erm-policy)# slot 1

Example:

Enters policy node configuration mode with the system command.

Enters ERM slot configuration mode with the slot slot-number command. This command is available only in distributed platforms like RSP.

Step 6

memory io

Example:


Router(config-policy-node)# memory io

(Optional) Enters memory owner configuration mode.

Allows you to set the rising and falling values for the critical, major, and minor thresholds.

Step 7

critical rising rising-threshold-value [interval interval-value ] [falling falling-threshold-value [interval interval-value ]] [global ]

Example:


Router(config-owner-memory)# critical rising 75 falling 65 interval 10 global

Example:

Allows you to set the rising and falling threshold values for critical levels as percentages of the I/O memory pool, and set the interval of time that must pass before these values are registered.

If the amount of memory held by the resource user exceeds the rising threshold value, a rising threshold notification is generated.
If the falling threshold notification is generated before the interval has passed, then the rising notification is not sent.
The interval following the rising threshold signifies this time period in seconds.
If the amount of memory held by the resource user falls below the falling threshold, the falling threshold notification is sent.
The optional global keyword indicates that the threshold is being set on the global memory consumption, not on the memory used by the particular resource user in which the configuration is being applied.

Note

If you had configured a global policy in Step 4, you do not need to give the global keyword while setting the threshold values in Step 7. However, if you have configured a user local or per-user global policy (by not specifying the global keyword) in Step 4, enter the global keyword in Step 7 if you want to configure a per user global threshold.

Step 8

exit

Example:


Router(config-owner-memory)# exit

Exits memory owner configuration mode.

Troubleshooting Tips

To trace and troubleshoot the notification and registration activities for resources using the Embedded Resource Manager feature, use the following suggested techniques.

Enable debugging of resource registration using the debug resource policy registration command in privileged EXEC mode.
Enable debugging of resource manager notification using the debug resource policy notification command in privileged EXEC mode.

SUMMARY STEPS

enable
debug resource policy registration
debug resource policy notification [owner resource-owner-name ]

DETAILED STEPS

Command or Action Purpose

Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2

debug resource policy registration

Example:


Router# debug resource policy registration

Enables debugging on resource policy registration.

Step 3

debug resource policy notification [owner resource-owner-name ]

Example:


Router# debug resource policy notification owner cpu

Enables notification debugging on ROs.

Examples

Use the debug resource policy registration command to trace the resource manager registration information, for example:


Router# debug resource policy registration 
Registrations debugging is on
When a Resource User is created
*Mar  3 09:35:58.304: resource_user_register: RU: ruID: 0x10000B8, rutID: 0x1, rg_ID: 0x0 name: usrr1
When a Resource User is deleted
*Mar  3 09:41:09.500: resource_user_unregister: RU: ruID: 0x10000B8, rutID: 0x1, rg_ID: 0x0 name: usrr1

Use the debug resource policy notification [owner resource-owner-name ] command to trace the resource policy notification information, for example:


Router# debug resource policy notification
 
Enabled notif. debugs on all owners

When a threshold is exceeded, you would see these messages:


*Mar  3 09:50:44.081: Owner: 'memory' initiated a notification:
*Mar  3 09:50:44.081: %SYS-4-RESMEMEXCEED: Resource user usrr1 has exceeded the Major memory threshold
Pool: Processor Used: 42932864 Threshold :42932860
*Mar  3 09:50:46.081: Notification from Owner: 'memory' is dispatched for User: 'usrr1' (ID: 0x10000B9)
*Mar  3 09:50:46.081: %SYS-4-RESMEMEXCEED: Resource user usrr1 has exceeded the Major memory threshold
Pool: Processor Used: 42932864 Threshold :42932860
Router# no debug resource policy notification
Disabled notif. debugs on all owners
Router# debug resource policy notification owner cpu
Enabled notif. debugs on owner 'cpu'
Router#

Configuration Examples for Embedded Resource Manager

Managing Resource Utilization by Defining Resource Policy Example

The following example shows how to configure a global resource policy with the policy name system-global-pc1:


configure terminal
resource policy 
policy system-global-pc1 global

The following example shows how to configure a per user global resource policy with the policy name per-user-global-pc1 and the resource type as iosprocess:


configure terminal
resource policy 
policy per-user-global-pc1 type iosprocess

The following example shows how to configure a user local resource policy with the policy name user-local-pc1 and the resource type as iosprocess:


configure terminal
resource policy 
policy user-local-pc1 type iosprocess

Setting Expected Operating Ranges for Resource Owners Example

The following example shows how to configure various thresholds for buffer, CPU, and memory ROs.

Configuring System Global Thresholding Policy for Buffer RO

The following example shows how to configure a global policy with the policy name as system-global-pc1 for public buffer with critical threshold values of 90 percent as rising at an interval of 12 seconds, 20 percent as falling at an interval of 10 seconds, major threshold values of 70 percent as rising at an interval of 12 seconds, 15 percent as falling at an interval of 10 seconds, and minor threshold values of 60 percent as rising at an interval of 12 seconds, 10 percent as falling at an interval of 10 seconds:


configure terminal

Setting a System Global Thresholding Policy for I O Memory Example

The following example shows the configuration of a global memory thresholding policy for I/O memory. In this example, the policy is given the name “system-global-io”, and the threshold for critical I/O memory usage is defined as being usage of over 90 percent of the globally available I/O memory pool for 12 consecutive seconds.

The critical falling threshold is also defined in this example (less than 20 percent of the globally available I/O memory pool for 10 seconds or more); however, only the critical rising level will affect when the automatic deallocation procedure is triggered.

Feature Information for Embedded Resource Manager

The following table provides release information about the feature or features described in this module. This table lists only the software release that introduced support for a given feature in a given software release train. Unless noted otherwise, subsequent releases of that software release train also support that feature.

Table 1. Feature Information for Embedded Resource Manager
Feature Name	Releases	Feature Information
Embedded Resource Manager	12.3(14)T 12.2(33)SRB 12.2(33)SB Cisco IOS XE Release 3.9S	The Embedded Resource Manager (ERM) feature allows you to monitor internal system resource utilization for finite resources such as the buffer, memory, and CPU. ERM monitors resource utilization from the perspective of various subsystems within the Cisco IOS software such as resource owners (ROs) and resource users (RUs). ERM allows you to configure threshold values for system resources, leading to better insight into system scalability and improved system availability.
Embedded Resource Manager MIB	15.0(1)M 12.2(33)SRB 12.2(33)SB Cisco IOS XE Release 3.9S	The ERM MIB feature introduces MIB support for the Embedded Resource Manager (ERM) feature. The ERM feature tracks resource usage information for every registered resource owner and resource user. ERM ensures efficient usage of available resources.The ERM MIB feature allows you to monitor the usage of resources by gathering resource usage information using MIB objects. The network manager can use the information collected by the ERM MIB objects to ensure the optimal use of the resources. The following command was introduced by this feature: snmp-server enable traps resource-policy.
Packet Memory Reclamation	12.4(6)T 12.2(33)SRE Cisco IOS XE Release 3.9S	The Packet Memory Reclamation functionality utilizes the ERM infrastructure to cleanup and reclaim leaked Cisco IOS packet memory using the Memory Leak Detector process (sometimes referred to as the “Garbage Detection” or “GD” process).

Glossary

CPUHOG --Each process is allocated a quantum of time, which is equivalent to 200 ms. If a process is running for more than 2 seconds, the process is hogging the CPU. This condition is called CPUHOG.

RM --resource usage monitors. Applications that wants to monitor resource utilization of resources by the resource users.

RO --resource owners. Provides resources to the resource users. For example, CPU, buffer, memory and so on.

RU --resource users. Applications or clients (like HTTP, SNMP, telnet, and so on) that use the resources and receive notifications to throttle when the current values exceed thresholds.
