Alert Definition Symptom Recommendations
Virtual machine has high CPU co-stop
due to snapshots.
Symptoms include all of the
following:
n
Virtual machine CPU co-stop is
at warning/immediate/critical
level
n
Virtual machine has at least one
snapshot
To reduce the high co-stop (%CSTP)
values and increase virtual machine
performance, consolidate any
snapshots into the main virtual disk. In
the vSphere Client, select the VM, right
click, and select Snapshot, and then
Consolidate. After consolidation, the
%CSTP value is reduced or eliminated
and VM performance is improved. If
performance is not improved enough,
continue researching other potential
VM performance issues. See VMware
KB: hp://kb.vmware.com/kb/2000058
Virtual machine has chronic high
memory workload leading to memory
stress.
Symptoms include all of the
following:
n
Virtual machine memory stress at
warning/immediate/critical level
n
Recommended virtual machine
memory size > 0
Add more memory for the VM.
Virtual machine is projected to run out
of disk space.
Symptoms include all of the
following:
n
Virtual machine disk space time
remaining low (<= 60 days)
n
! Guest le system space usage
above DT
n
! Guest le system overall disk
space usage reaching warning
limit (85%)
n
Guest partition disk space usage
1 Check the application
conguration to determine
whether the virtual machine disk
capacity will be sucient.
2 Add a new hard disk to the virtual
machine and congured the guest
le system partition to use the
disk.
