You also should do this when monitoring a host via frontman - in such situation, the host checks you specify would be performed by the frontman.
To specify the checks for a host, locate it on the Hosts page and select the Edit button for it. This way you can access the Settings page for the host, where you can view, add, and modify the host checks.
The checks you specified are displayed in the Settings page. You can also view the check results in the Latest data page for the host.
