CiscoBufferUtilization

Path: /model/vendors/cisco/cisco_buffer_utilization.mod

Monitors the free element buffers on Cicso routers to determine if their buffer availability is at acceptable levels. If buffer availability is less than five percent for three poll intervals, then NerveCenter sends a 6005 Inform to the platform.

Two additional alarms, CiscoBufferUtilization_LogToDB and CiscoBufferUtilization_LogToFile, are part of this model. When you enable these alarms, they perform a Log To Database or a Log to File alarm action, respectively, on each transition so that reports on buffer utilization can be produced.

Note    The LogToDB alarm, works on Windows NT only.

Trigger Generators

Below is a list of the objects that generate triggers:

• CiscoBuffersCheck (poll)

Events Sent to OpenView

The table below summarizes the events this behavior model sends to OpenView:

For complete information about events sent to OpenView, see the trapd.conf.txt file shipped with these behavior models residing in:

/model/vendors/cisco

For more information about integrating NerveCenter with OpenView, or the other NerveCenter-supported network manager platforms, refer to the book Integrating NerveCenter with a Network Management Platform.

Optional Customization

Below is a list of behavior model settings that you might want to customize to suit the requirements of your site.

Tip    It's a good practice to rename the behavior model objects that you modify. Whenever you import a model, NerveCenter will overwrite objects with the same name.

---

• Set timers for persistence
• Poll intervals
• Poll conditions for buffer utilization thresholds
• Change Inform to Inform Platform for Netcool, TME, Unicenter
• Log To File alarm action options
  (file pathname, log action variables, verbose or non-verbose output)
• Log To Database alarm action options
  (log identity number and log action variables)
