munin_plugins 4.2

Requirements

• Python >= 2.7

• psutil for Python

• Monit

• Munin-node

• Nginx

Install Egg

As usual, egg is installable using setuptools or pip, choice what you like. It is better and strongly suggested to use a virtualenv.

Install

The fast way to install, is using generate.py. To use, simply call generate script in bin directory.

# <virtualenv_path>/bin/generate

It will test the environment and configure cache folders. For every sensor, it will ask a confirm. Every sensor creates in /etc/munin/plugin-conf.d a single configuration. If you want to check/change, that is the place.

Restart munin-node, munin-async (if you use that) and enjoy.

Configure

Usually a manual configuration is not required, but in some case you have to modify some path or else. All munin plugins ask by they self during installation what they need, and they write in /etc/munin/plugin-conf.d. Keep attention if you reinstall using generate script because all setup will be overwriten.

For apache and nginx, you have to configure log file format using combined2:

Apache: LogFormat “%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i" [[%D]]” combined2

Nginx: log_format combined2 ‘$remote_addr - $remote_user [$time_local] ‘

‘”$request” $status $body_bytes_sent ‘ ‘”$http_referer” “$http_user_agent” [[$request_time]]’;

After combined2 definition, you have to change your virtualhost configuration using this format instead of usual “combined”.

Known Problems

1 - Keep attection if you use SELinux or other kind of Security access framework, because you have to configure all rights correctly. Usually, my choice is to put down, because the call of monit get error about access denied.
