Description

Monitors the Cisco buffer statistics such as memory buffer hit rate, miss rate and utilization.

Prerequisites

SNMP should be enabled in end device and device should support CISCO-ENHANCED-MEMPOOL-MIB OIDs and SNMP credentials should be attached against the device in portal.

How to Apply: This template is All instance selection based. It will not ask user to select any instance (s) while assigning it to a device.

Metric Parameters

Metric Parameters
ParameterDescription
Frequency
  • Frequency is the interval in which you want to probe and collect metric data from the target device/resource
  • Frequency is defined in minutes (min).
    • Warning ThresholdIf the metric value satisfies the condition defined along with Warning Threshold value, then a notification is sent to the user.
    Critical ThresholdIf the metric value satisfies the condition defined along with Critical Threshold value, then a notification is sent to the user.
    AlertThe alert value can be set to either Yes or No. If it is Yes, then an alert message is sent to the user.
