Monitoring policies control how Cisco EPN Manager monitors your network by controlling the following:
What is monitored—The network and device attributes Cisco EPN Manager monitors.
How often it is monitored—The rate at which parameters are polled.
When to indicate a problem—Acceptable values for the polled attributes.
How to indicate a problem—Whether Cisco EPN Manager should generate an alarm if a threshold is surpassed, and what the alarm severity should be.
Monitoring policies are important because apart from controlling what is monitored, they determine what data can be displayed in reports, dashboards, and other areas of Cisco EPN Manager . Monitoring policies do not make any changes on devices.
Only device health monitoring (that is, the Device Health monitoring policy) is enabled by default. Interface Health monitoring is not enabled by default to protect system performance in large deployments. Note that the Device Health monitoring policy does not apply to the Cisco NCS 2000 and Cisco ONS families of devices. To monitor those device types, use the optical monitoring policies listed in Monitoring Policies Reference.
These steps summarize how you can configure a monitoring policy.
Use a monitoring policy type as a template for your monitoring policy, and give the policy a name that is meaningful to you. Policy types are packaged with Cisco EPN Manager and make it easy for you to start monitoring different technologies and services, such as Quality of Service, Optical SFP, and TDM/SONET. A complete list is provided in Monitoring Policies Reference.
Adjust your policy's polling frequencies or disable polling altogether for specific parameters.
Specify the threshold crossing alarms (TCAs) you want Cisco EPN Manager to generate if a parameter's threshold is surpassed. Some TCAs are configured by default; you can adjust or disable them, and configure new TCAs.
Specify the devices you want your policy to monitor. Devices are filtered depending on the policy type.
To view and administer monitoring policies, choose

Description |
Automonitoring |
Lists the policies that are enabled by default in Cisco EPN Manager . Only the Device Health monitoring policy is enabled by default. You can adjust the settings for this policy. |
My Policies |
The policy you create is listed here. When you choose a policy from My Policies, you can view the policy's details. |
The Device Health monitoring policy is enabled by default. It checks managed devices for CPU utilization, memory pool utilization, environment temperature, and device availability. This policy also specifies thresholds for utilization and temperature which, if surpassed, trigger alarms that are displayed in the GUI client.
To view the current settings for this policy, choose Automonitoring from the list on the left. You can also adjust the polling frequency and threshold for the different parameters. To adjust a polling frequency or threshold, use the drop-down lists that are provided in the GUI client.
, then selectYou might also want to create a device health monitoring policy that monitors specific devices—for example, devices of a certain type or in a certain geographical location. For instructions on how to do this, see Adjust What Is Being Monitored.
Interfaces are not monitored by default. This protects system performance for networks with large numbers of interfaces. Use this procedure to set up basic interface monitoring.
To set up and enable interface monitoring:
Step 1 | Choose My Policies from the list on the left. , then select |
Step 2 | Click
Add to create a new policy.
|
Step 3 | Choose
Interface Health for generic interface monitoring.
If you are monitoring optical devices, choose
Optical 15 Mins or another optical policy (see
Monitoring Policies Reference).
When you select a policy, Cisco EPN Manager populates the window with the policy settings. |
Step 4 | Enter a meaningful name and description. |
Step 5 | From the
Device
Selection drop-down list, select the devices (or device groups) you
want to monitor.
Cisco EPN Manager
only lists devices applicable to that policy.
If you want to use the default settings for polling and thresholds, proceed to step 8. |
Step 6 | To adjust how
often the interface is polled, select a value from the
Polling
Frequency drop-down list. Some policies allow you to set polling
frequencies for different parameters, while other policies have only one
polling frequency that is applied to all parameters.
For example, the following shows a policy that will monitor Cisco ASR 9000 interfaces. It uses the Interface Health policy type, where a all parameters are polled using the same interval. Alternatively, the following shows a policy that will monitor Cisco NCS 2000 interfaces. It uses the Optical 15 mins policy type, where each interface type has its own polling interval. You can edit the interval by double-clicking it. |
Step 7 | If the policy supports TCA customization, you can adjust the thresholds. See Change Thresholds and Alarm Behavior for a Monitoring Policy. |
Step 8 | Click: |
Cisco EPN Manager provides a variety of dashboards for monitoring your devices and network. The following are some examples of what dashboards can provide:
For information on dashboards, see Set Up and Use the Dashboards.
This topic explains how to get the following information:
Which policies are activated, their status, and their history.
The specific parameters that Cisco EPN Manager is polling, the frequency at which they are polled, and their threshold crossing alarm (TCA) settings.
Who created the policy and which policy type they used as its basis.
To find out what a policy polls, when the policy last ran, and whether the policy is currently active, choose My Policies. Cisco EPN Manager lists the monitoring policies you created or have access to, with the following information.
, then choose

To check a monitoring policy's past data collection:
You can customize how often monitoring information is gathered (polling interval). Not all policies have all of these settings; for example, a policy may only collect statistics, so it would not have any thresholds or alarms associated with it.
You can customize how often monitoring information is gathered (polling interval). Not all policies have all of these settings; for example, a policy may only collect statistics, so it would not have any thresholds or alarms associated with it.
You can customize the threshold value that indicates a problem and whether Cisco EPN Manager should generate an informational event or an alarm (of an severity) when a problem is detected. Not all policies have all of these settings; for example, a policy may only collect statistics, so it would not have any thresholds or alarms associated with it.
When you run a performance test, Cisco EPN Manager connects to the network devices in real time to retrieve the information. Reports, on the other hand, use historical data that is saved in the database. See these topics for more information, depending upon the type of test you want to run:
Cisco EPN Manager also supports performance tests on OTS optical links. For more information, see Run a Performance Test on a Link (OTS Link).
Cisco EPN Manager provides a variety of reports to help you monitor your network's performance. The following are some examples:
Environmental temperature, CPU and memory utilization
Interface errors and discards
For Carrier Ethernet devices—IPSLA Ethernet OAM, PWE3, QoS, and other CE reports
For Optical devices—Ethernet, OTN, SDH/SONET, and other optical reports
When you run a performance report, retrieves historical data that has been saved in the database. Reports can only display data that Cisco EPN Manager has been configured to collect—in other words, data that is collected and monitored using monitoring policies. (No monitoring policies have to be enabled for event and alarm-related reports; that data is collected automatically.) For information on which monitoring policies must be enabled for the different reports, see Reports Available.
