I have 3 script monitors that run successfully on a large number of Unix boxes that check 1) too many su to root failures, 2) too many failed logins, and 3) LVM status (metastat). But - there are a few servers where one or more of these monitors is grayed out; i.e. in and "Unknown State".
From the "Assigned Application Monitors" screen, I test the monitor and it works fine - every time, on every node that is supposedly in an unknown state. The settings are identical to the other monitors in that there are no template over-rides.
Any insight and/or suggestions welcome.
