OpManager Plus 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 Plus 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'.
