What is HUM?

CiscoWorks HUM is a software application that allows the network administrator to monitor the health and utilization of devices connected to the network.

CiscoWorks HUM monitors the device for performance parameters such as CPU utilization, memory utilization, interface utilization, interface availability, device availability and so on. HUM does this by querying the device through Simple Network Management Protocol (SNMP).

Key Features of HUM

The key features of HUM are:

•Measures network performance by monitoring device components such as memory, CPU, interface ports for their Utilization and Availability levels.

•System-defined MIB templates for user convenience

CiscoWorks HUM provides System-defined MIB templates that allows network administrators to create Pollers easily. System-defined MIB templates provide most of the common network parameters that is needed to monitor a device connected to the network.

•User-defined MIB templates

CiscoWorks HUM allows network administrators to create custom or user-defined MIB templates by leveraging MIB variables from System-defined MIB templates or by grouping new MIB variables.

•Supports polling of additional SNMP data

CiscoWorks HUM allows network administrators to add any other Cisco MIB apart from the standard MIBs provided as part of the application to create pollers.

•Flexible polling frequencies

CiscoWorks HUM provides flexible polling frequencies or intervals ranging between 1 minute and 8 hours.

•Historical trending reports

CiscoWorks HUM offers comprehensive reporting on the data collected by polling the device. The polled information is displayed in the form of reports. These reports help the network administrator to analyze the utilization and availability of devices connected to the network. For more information, see Reports.

•Top-N/Bottom-N reporting

Provides Top-N/Bottom-N reporting on devices that have the highest/lowest utilization or availability values.

•Alerts and notifications

CiscoWorks HUM allows network administrators to set threshold values against the utilization and availability levels of device parameters such as memory, CPU, interface and so on. If threshold values are violated, HUM notifies the network administrator through e-mails. For more information, see Threshold Configuration.

•Triggers external commands or scripts on receiving threshold violation alerts

CiscoWorks HUM supports triggering of user specified external commands or scripts to take appropriate action against threshold violations. For more information, see Threshold Configuration.

•Scalability Limits

CiscoWorks HUM supports scalability of upto 1000 devices.

Table 1-1 describes the scalability of HUM in standalone and bundle environments.

–Standalone—HUM with CiscoWorks Common Services 3.2, LMS Portal 1.1 and CiscoWorks Assistant 1.1.

–Bundle—HUM with LAN Management Solutions (LMS) 3.1

Table 1-1 Scalability Limits

Devices	Environment Type	MIB Objects Polled
300 Devices	Standalone (300 HUM SKU)	30,000 MIB objects
	Bundle (300 HUM SKU + 1500 LMS SKU)	20,000 MIB objects
1000 Devices	Standalone (1000 HUM SKU)	100,000 MIB objects
	Bundle	Not Supported

For server requirements, see Installing and Getting Started with CiscoWorks LAN Management Solution 3.1

Note CiscoWorks HUM supports polling of only Cisco devices. If you add any other devices, HUM still allows these devices to be added to pollers. However, the application behavior may not be as expected.
