Re: Config working on CentOS 5 stopped working on CentOS 6

[Stas Oskin]

Hi,

The monit log shows only the general start-up information.

There is no messages about the processes going offline, it's like monit does not use the pid file to find the process anymore.

When I use HTTP port probing though it works just fine. Any idea what could it be?

Regards.

Hi,

please can you provide more details about the problem? (error messages and/or monit log).

Note that monit 5.9 includes fix for program execution for CentOS6/RHEL6, we recommend upgrade to latest monit version (5.15), you can get it here: https://mmonit.com/monit/#download. You can build rpm directly from the source code release: rpmbuild -tb monit-5.15.tar.gz. I think RHEL uses custom configuration file, official monit looks for /etc/monitrc, so you may need to rename the configuration file or create a link after upgrade.

Regards,
Martin
