In a vSphere High Availability cluster, what is the VM Monitoring I/O stats interval default value?
A.
60 seconds
B.
90 seconds
C.
120 seconds
D.
180 seconds
Explanation:
Occasionally, virtual machines or applications that are still functioning properly stop sending heartbeats. To avoid unnecessary resets, the VM Monitoring service also monitors a virtual machine’s I/O activity. If no heartbeats are received within the failure inter’al, the I/O stats interval (a cluster-level attribute) is checked. The
I/O stats interval determines if any disk or network activity has occurred for the virtual machine during the previous two minutes (120 seconds). If not, the virtual machine is reset. This default value (120 seconds) can be changed using the advanced attribute das.iostatsinterval.
