File existence alarm in Monit

I have been using monit for some time, but I want to signal if the file exists. This is the opposite of using the main documentation .

The document says here:

IF [DOES] NOT EXIST [[<X>] <Y> CYCLES] THEN action [ELSE IF SUCCEEDED [[<X>] <Y> CYCLES] THEN action]
action is a choice of "ALERT", "RESTART", "START", "STOP", "EXEC" or "UNMONITOR".

This gives me a recipe for "freak out if the file is missing." But I want to "worry if the file is there." And the choice of actions implies that actions "do nothing." I could put it on no-op, but it's really stupid for the standard case of "do nothing."

I suggested some basic cases:

IF EXISTS THEN alarm
IF EXIST THEN ALARM

So, is there a standard way to do this IF IT DOES EXIST?

renab, your check should end with "then alert" and not with "then alarm", at least in my version (5.2.5).

testfile with path /path/to/file
  if not exist then exec "/bin/bash -c 'echo dne > /dev/null'" else if succeeded then alert
