Use this Knowledge Script to monitor host uptime in days. Host uptime is the time elapsed since the last system startup. This script raises an event when a host is rebooted, and it collects data for host uptime.
NOTE:
When a host goes into maintenance mode all VirtualCenter_Host* Knowledge Scripts, except for the VirtualCenter_HostConnected Knowledge Script, suppress events and data.
In rare situations, queries to the ESX or ESXi host might fail with timeouts because the ESX or ESXi host stops responding. This issue affects all VirtualCenter_Host* Knowledge Scripts. You can work around this issue by restarting the management service on the ESX or ESXi host.
vSphere ESX or ESXi host
By default, this script runs every 5 minutes.
