From the manual;
CHECK PROGRAM <unique name> PATH <executable file> [TIMEOUT <number>
SECONDS]
<path> is the absolute path to the executable program or script. The
status test allows one to check the program's exit status. If the
program does not finish executing within <number> seconds, Monit
will terminate it. The default program timeout is 300 seconds (5
minutes). The output of the program is recorded and made available
in the User Interface and in alerts, by default up to 512 bytes. You
can change the output limit using the set limits statement).”
Two things to note here, you program must end with a call to exit and
it should exit 0 if all is okay and exit 1 if error. You then write the test as
follows:
check program checkUSB with path "/usr/local/sbin/checkUSB.sh"
if status != 0 then alert
Ps .The content test i primarily for testing file content.
