Re: [monit] check file - if missing to do XX? possible?

[Martin Pala]

You are right ... the same situation was fixed for size test only.

I have fixed the same for the checksum test as well, you can get the 
fixed version from cvs: http://savannah.nongnu.org/cvs/?group=monit


Test case configuration:
--8<--
set daemon  5
set logfile /var/log/monit
set httpd port 2812
    use address localhost
    allow  localhost

check file test with path "/tmp/test"
  start program = "/bin/touch /tmp/test"
  if changed checksum then exec "/bin/true"
--8<--


1.) On start monit detects the file doesn't exist and calls the start 
program:
--8<--
Starting monit daemon with http interface at [localhost:2812]
Starting monit HTTP server at [localhost:2812]
monit HTTP server started
'unicorn' Monit started
'test' file doesn't exist
'test' trying to restart
Monitoring disabled -- service test
'test' start: /bin/touch
Monitoring enabled -- service test
'unicorn' Monit has not changed
'test' file existence check succeeded
'test' file exist
'test' is a regular file
--8<--

2.) when the checksum changes, the script is executed:

--8<--
'test' checksum was changed for /tmp/test
'test' exec: /bin/true
--8<--
