Alert Definition Symptoms Recommendations
Host in a non-DRS cluster has memory
contention due to overpopulation of
virtual machines.
Symptoms include all of the
following:
n
Host inside a cluster
n
[ ! DRS Enabled OR ! DRS fully
automated ]
n
Host memory workload at
warning/immediate/critical level
n
Host memory contention at
warning/immediate/critical level
n
Zero child virtual machines have
[ Virtual machine memory
workload at
warning /immediate/critical
level ]
1 Use vSphere vMotion to migrate
some virtual machines with high
memory workload to other hosts
that have available memory
capacity.
2 Upgrade the host or use a host that
has larger memory capacity.
Host is experiencing high number of
received packets dropped.
Symptoms include all of the
following:
n
Host network received packets
dropped
n
Host network received packets
dropped above DT
n
Host network data receive
workload at Warning level
n
Host network data receive
workload above DT
n
Host CPU demand at Critical
level
1 If the host has one CPU, upgrade
the host or use a host that has
larger CPU capacity.
2 Add an additional NIC to the host.
3 Reduce the amount of network
trac being generated by virtual
machines by moving some of them
to a host with lower network
trac.
Host is experiencing high number of
transmied packets dropped.
Symptoms include all of the
following:
n
Host network transmied
packets dropped
n
Host network transmied
packets dropped above DT
n
Host network data transmit
workload at Warning level
n
Host network data transmit
workload above DT
n
Host is dropping high percentage
of packets
1 Add an additional NIC to the host.
2 Reduce the amount of network
trac being generated by virtual
machines by moving some of them
to a host with lower network
trac.
ESXi host has detected a link status
'apping' on a physical NIC.
Physical NIC link state apping (fault
symptom).
ESXi disables the device to avoid the
link apping state. You might need to
replace the physical NIC. The alert will
be canceled when the NIC is repaired
and functioning. If you replace the
physical NIC, you might need to
manually cancel the alert.
ESXi host has detected a link status
down on a physical NIC.
Physical NIC link state down (fault
symptom).
ESXi disables the device to avoid the
link apping state. You might need to
replace the physical NIC. The alert will
be canceled when the NIC is repaired
and functioning. If you replace the
physical NIC, you might need to
manually cancel the alert.
