The system health thresholds are pre-defined. When the CPU and memory utilization crosses the pre-defined threshold values, SNMP events are generated.
For example, assuming the memory utilization threshold value for the process ‘netdevd’ is 1GB and the system health threshold is enabled, when the memory utilization for netdevd crosses 1GB, an SNMP trap can be generated.
These SNMP events help in troubleshooting. Collect this information and report it to Gigamon Technical Support. A Gigamon Technical Support personnel can use this information to resolve the CPU and memory utilization issues. Refer to Contact Technical Support on page 345.
Use the following command to enable the system health threshold for all the nodes in the cluster:
(config) # system-health threshold enable
You can also enable the system health threshold for a specified node. For example, if you want to enable the system health threshold for box ID 10, then use the following command:
config) # system-health box-id 10 threshold enable
Use the following command to disable the system health threshold:
(config) # no system-health threshold enable
