Alert Definition Symptoms Recommendations
DRS-enabled cluster has unexpected
high CPU workload.
Symptoms include all of the
following:
n
DRS enabled
n
DRS fully automated
n
Cluster CPU workload above DT
n
Cluster CPU workload at
warning/immediate/critical level
1 Check the applications running on
the virtual machines in the cluster
to determine whether high CPU
workload is an expected behavior.
2 Add more hosts to the cluster to
increase CPU capacity.
3 Use vSphere vMotion to migrate
some virtual machines to a
dierent cluster if possible.
DRS-enabled cluster has memory
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 memory contention at
warning/immediate/critical level
n
> 0 descendant virtual machines
have [ Virtual machine memory
workload at
warning /immediate/critical
level ]
n
<= 50% of descendant virtual
machines have [Virtual machine
memory workload at warning/
immediate/critical level ]
Use vSphere vMotion to migrate some
virtual machines to a dierent cluster
if possible.
DRS-enabled cluster has memory
contention caused by more than half of
the virtual machines.
Symptoms include all of the
following:
n
DRS enabled
n
DRS fully automated
n
Cluster memory contention at
warning/immediate/critical level
n
Cluster memory workload at
warning/immediate/critical level
n
> 50% of descendant virtual
machines have [ Virtual machine
memory demand at warning/
immediate/critical level ]
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 memory capacity.
DRS-enabled cluster has memory
contention caused by overpopulation
of virtual machines.
Symptoms include all of the
following:
n
DRS enabled
n
DRS fully automated
n
Cluster memory contention at
warning/immediate/critical level
n
Cluster memory workload at
warning/immediate/critical level
n
== 0 descendant virtual machines
have [ Virtual machine memory
demand at
warning /immediate/critical
level ]
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 memory capacity.
