Description
Monitors the hits, misses and failures for small, big, medium, large and huge buffers.
Prerequisites
SNMP should be enabled in end device and device should support OLD-CISCO-MEMORY-MIB OIDs and SNMP credentials should be attached against the device in portal.
Metric Parameters
Parameter | Description |
---|---|
Frequency | |
Warning Threshold | If the metric value satisfies the condition defined along with Warning Threshold value, then a notification is sent to the user. |
Critical Threshold | If the metric value satisfies the condition defined along with Critical Threshold value, then a notification is sent to the user. |
Alert | The alert value can be set to either Yes or No. If it is Yes, then an alert message is sent to the user. |
