Why each option
vSphere HA VM Monitoring uses an I/O stats interval to determine whether a VM is active; the default value is 120 seconds.
60 seconds is not the default I/O stats interval; it is shorter than the actual default and would cause more aggressive VM resets than intended.
90 seconds is not the documented default value for the I/O stats interval in vSphere HA VM Monitoring.
The default VM Monitoring I/O stats interval is 120 seconds, during which vSphere HA samples disk and network I/O activity. If no I/O is detected within this window and VMware Tools heartbeats are also absent, HA concludes the VM has failed and resets it.
180 seconds is longer than the actual default and corresponds more closely to a failure interval setting rather than the I/O stats sampling interval.
