Memory - Cisco Check
Memory - Cisco monitors memory pool utilization on any Cisco device using SNMP. The device must publish its memory usage in the CISCO-MEMORY-POOL-MIB.
Basic Check information
|Instances on a Device||1|
If the MEMPOOL_GLOBAL_SHARED pool information is queried using SNMP, it results in CPU hogs. It is evident that you might see packet drops/overruns at times of bursty/overloaded traffic when you use SNMP to poll memory statistics that require the ASA to query the information through huge chunks of memory that it is associated which results in SNMP related CPU hogs.
|Failed||Please check that the correct SNMP community string is configured in Network Discovery for the device|
