OpManager fetches events from each ESX Host,
similar to SNMP traps. Currently we support important events, and this
list is updated every release. Apart from host events,
OpManager also monitors threshold for critical performance indicators
and raises alerts. The complete list of threshold violation alerts and supported events are shown below in
Table 1 and Table 2 respectively.
To change the pre-set threshold values for each
performance monitor, go to the snapshot page of the host or VM. For
the hosts, check for Inventory Details-> Monitors section. For VMs,
check
for Monitors-> VM Performance Monitors. All
the VM specific performance monitors are grouped under 'VM Performance
Monitors'.
