A host is a machine where managed databases and other services reside. To view all the hosts monitored by Oracle Enterprise Manager, select Hosts on the Targets tab of the Enterprise Manager Grid Control.
From the Hosts page, you can:
View whether a particular host is available and whether there are warning or critical alerts associated with that host.
View the default list of metrics for the hosts. Although there is a default list of metrics that display on the Host page, this list of metrics can be changed using the Customize Table Columns page accessed from Preferences.
View detailed information about each metric by clicking the number associated with the metric for that host.
View statistics applicable to each host by clicking the host name.
