Unable to get monit service check to timout (v4.5)

[Waggott, Graeme]

Hi there

 

I am a recent user of monit and am finding it very useful for application monitoring with a view to use it with some bespoke applications and heartbeat.  I started with version 4.4 on RedHat Linux ES3.0. 

 

Using version 4.4 I had everything running fine with services creating their own pid files via bespoke service scripts.  When I forced an application to fail by removing it's required configuration file, after 2 restarts in 3 cycles the monitoring timed out as expected.  Unfortunately I couldn't get the restart count to reset on unmonitor and so it was in constant timeout.  Hence moving to version 4.5 for the suggested bugfix in the release note.

 

I am using exactly the same monitrc file and applications as I used before but this time I cannot get a service to timeout upon forcing a failure. Has anything changed within monit?  The monitrc looks pretty much like this

 

********

set daemon  20           # Poll at 20 second intervals
set logfile syslog facility log_daemon # Set syslog logging
set init
set httpd port 2812
    use address localhost
    allow localhost

 

check process monkey with pidfile /var/run/monkey.pid
        start program = "/etc/init.d/monkey start"
        stop program = "/etc/init.d/monkey stop"
        if 2 restarts within 3 cycles then timeout

*********

 

I was thinking that it may be something to do with the pidfile.  The init script of monkey simply echo's the pid created upon startup to the /var/run/monkey.pid file although monkey does start in the background with an &.  Not sure what effect this is having upon the pid.  Although it did work in the previous release of monit. 

 

Please find some output below.  This same output is repeated forever without the monitoring timing out

 

Any advice would be appreciated

 

Cheers
