To Monitor a Server or a Server Group

The following procedure describes how to use the command line to enable the monitoring of hardware health and operating system health of a server or a server group. Hardware health and OS health monitoring are both enabled with this command, provided that the OS monitoring feature has been installed on the server or the server group. If the OS monitoring feature has not been installed on the server or server group, then only hardware health monitoring is enabled.
