RE: monit watchdog timer restart

[Peter Holdaway]

I have tried this and the stop action does not affect the process.

monit.log says...

[ Feb 24 14:32:18] start: (AppManager) /opt/lxs/bin/lxs.sh
[ Feb 24 14:34:37] Event: timestamp test failed for
/var/lxs/run/AppManager.monit


monit status says...

Process 'AppManager'                running
File 'AppManager_monit'             not monitored


Is this a bug?

Regards,

  Peter
