Identifying Monitoring Failure

If monitoring is enabled, as described in Enabling and Disabling Monitoring, and the status in the output of the show server or show group commands is unknown or unreachable, then the server or server group is not being reached successfully for monitoring. If the status remains unknown or unreachable for less than 30 minutes, it is possible that a transient network problem is occurring. However if the status remains unknown or unreachable for more than 10 minutes, it is possible that monitoring has failed. This could be the result of a failure in the monitoring feature. For more information, see Resolving Command Failures Related to OS Monitoring.

If monitoring traps are lost, a particular threshold status may not be refreshed for up to 30 hours, although the overall status should still be refreshed every 10 minutes.

A time stamp is provided in the monitoring data output. The relationship between this time stamp and the current time can also be used to judge if there is an error with the monitoring agent.
