Lines 3-5: Defines the context for the Event's rule evaluation.
Line 4: The context specifies for all VM Host objects, so the Event Service iterates over all VM
Hosts. On each VM Host, the
composed of one or more VM Hosts.
Lines 7-12: Defines the Trigger rule to determine if this Event is to fire notifications or not. If the
trigger rule does not pass, then no Event notifications occur.
Line 8: Consider only VM Hosts that have at least one VM instance running.
Line 9: Check the running average of the VM Host's load average if it exceeds a threshold value. In
this case if the average is greater than 2.
Lines 12-14: Defines the Reset rule to determine if a previously triggered VM Host can be reset and
triggered again.
Line 13: Only reset if the running average of the VM Host's load average drops below a threshold.
So when a VM Host passes the trigger rule, the VM Host does not pass the trigger rule again until
the reset rule (load average drops below threshold) passes.
