Monitoring php-fpm

[nokiomanz]

Hello everyone!

This morning I decided to install this Checkmk Exchange
But I am facing a few problem.

I am running a Ubuntu20.04 cmk server and I am under the version 2.0.0p4.
I added the check on the host I want to monitor under

/usr/lib/check_mk_agent/plugins/php_fpm_pools

I also added the config under

cat /etc/check_mk/php_fpm_pools.cfg
php_fpm = [
{“socket”: “/var/run/php/php7.3-fpm.sock”, “path”: “/status”}
]

Under ubuntu20.04 it seems that by default there is no python but there is python3 so I had to modify the start of the script to say

#!/usr/bin/env python3

Executing the file now gives me a

Traceback (most recent call last):
File “./php_fpm_pools”, line 140, in
execfile(config_file)
NameError: name ‘execfile’ is not defined

So I modified line 140 from

execfile(config_file)

to

exec(open(“/etc/check_mk/php_fpm_pools.cfg”).read())

I now get the desired output on the server be it from the script directly of from the check_mk_agent

<<<php_fpm_pools>>>
www dynamic start_time 1636382097
www dynamic start_since 7680
www dynamic accepted_conn 14413
www dynamic listen_queue 0
www dynamic max_listen_queue 0
www dynamic listen_queue_len 0
www dynamic idle_processes 149
www dynamic active_processes 1
www dynamic total_processes 150
www dynamic max_active_processes 200
www dynamic max_children_reached 1
www dynamic slow_requests 0

Now when I go to check_mk under wato and rescan the host. I don’t see anything php-fpm related appear. And this is where I am stuck. If someone had the chance to play with this.

Thanks in advance

It seems that after a few hours ( i went to do something else) the cmk server realized there was something new. It seems to work and I am able to add the check from WATO. I will look and see if it all now seems correct.

[nokiomanz]

It is working.
I added a new php-fpm server to the monitoring and it’s all good.
So I guess the only thing that remain is the fact that some modification were necessary to make it work under ubuntu20.04/python3.

Hope this is usefull to someone at some point.

Have a great day everyone.

The execfile problem is already fixed inside the github repo
But it would be good that you have a symlink in your system from python to python3 if only this one is installed.

Noted for the github repo part.
Hope I did not add too much noise!

And you are right about python. I am toying with the idea more and more to just have a python symlink since I am only using the default installed python3 under ubuntu.
