Re: monit stops shutdown

[Guillaume François]

When told to shutdown the OS should stop all services, including Monit, shouldn't it?

-> It depends of how it was package for CentOS. And operating system supervisor will only handle processes it managed and know how to manage.

If CentOS package maintainer did crap integration for Monit in CentOS, it won't stop itself. Best is to perform a test on a clean system only with Monit and see the behavior.

On your CentOS version, how is Monit managed (start/stop) by the operating system ? Do it use system.d script ? service scripts ? init script ?

In the past, when requiring OS shutdown, after some time (timeout reach), the operating systems were issuing a soft kill then a hard kill signal. This is not the case anymore as all processes should be managed by operation system supervisor like upstart or system.d

Note that should is not a MUST. It people do crap, they have to clean up their crap.

the processes that monit controls are fully controlled by monit, so the OS doesn't touch them

Hello,

Are you using Monit to restart the processes when they "fail" ? If shutdown process stop them but Monit start them back you'll go into a loop mostly. Il already encountered this kind of loop.

Anyway, it would be better to stop Monit as part of the shudown process no ?

Best Regards.

Hi

I have several virtual centos 6.8 x64 VM's with monit-5.14-1.el6.x86_64 installed. I am finding that I can tell a VM to shutdown (either from the hypervisor or commandline), the standard message is sent and then it doesn't shutdown. I've waited hours and no shutdown, If I stop monit however at that point the shutdown proceeds normally.

Has anyone seen this? would a more up-to-date version fix it?

(Oh and its not consistent, sometimes the system does shutdown)
