Cluster Compute Resource Alert Definitions
The vCenter adapter provides alert denitions that generate alerts on the Cluster Compute Resource objects
in your environment.
Health/Symptom-Based
These alert denitions have the following impact and criticality information.

Alert Definition Symptoms Recommendations
DRS-enabled cluster has CPU
contention caused by less than half of
the virtual machines.
Symptoms include all of the
following:
n
DRS enabled
n
DRS fully automated
n
Cluster CPU contention at
warning/immediate/critical level
n
> 0 descendant virtual machines
have [ Virtual machine CPU
demand at warning/
immediate/critical level ]
n
<= 50% of descendant virtual
machines have [Virtual machine
CPU demand at warning/
immediate/critical level ]
Use vSphere vMotion to migrate some
virtual machines to a dierent cluster
if possible.

1 Use vSphere vMotion to migrate
some virtual machines to a
dierent cluster if possible.
2 Add more hosts to the cluster to
increase CPU capacity.
