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 to 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, traps and syslogs. For more information, see Threshold Configuration.
•
TrendWatch
TrendWatch ensures that the capacity, performance or utilization of critical resource remains within the defined service level. It also helps in capacity planning.
You can configure TrendWatches through HUM by setting up rules for each MIB-variable or on thresholds for a specific time period. TrendWatches can be scheduled (Immediate, Once, Daily, Weekly, or Monthly) as a job and can be configured to send notifications through email, traps and syslogs. For more information, see TrendWatch Configuration.
•
Trap and Syslog support
CiscoWorks HUM supports sending of Traps and Syslogs to respective receiver groups. It also sends e-mail notifications when TrendWatch violations occur in HUM.
•
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.
•
User configurable Quick Reports
You can configure the frequency and the time to generate Quick Reports that supports report-wise scheduling. This will serve as a performance tuning parameter for you.
This feature allows you to enable or disable generating any Quick Report and also to change the frequency of report generation. By default, reports are generated every hour and all Quick reports are enable.
By default, the report generation time or schedule is spread over a period of time. If you try to configure the generation of all Quick Reports at the same time, you will be prompted to change the schedule time of the reports.
•
Overlay Graphs
CiscoWorks HUM allows you to compare the historical trending of two MIB variables in the same graph in Quick Reports.
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.
