Munin plugins collection

Introduction

This is my collection of munin plugins that I use to monitor production servers. This servers include the following services: - Nginx - Multiple virtual hosts - Rails applications - Static web sites - Git repositories

Requirements

awk
ps -oe support

Install

This guide will allow you to install the plugins on ubuntu 10.04 LTS. However, It may work on other debian / ubuntu distribution

In order to install this scripts you need to enable the plugins on each munin-node.

# Set up nginx plugins
cp nginx_* /usr/share/munin/plugins
for file in `ls /usr/share/munin/plugins/nginx_*`
  do
  ln -s $file /etc/munin/plugins
done

# Set up users plugins
cp byuser_* /usr/share/munin/plugins
for file in `ls /usr/share/munin/plugins/byuser_*`
  do
  ln -s $file /etc/munin/plugins
done

Now you need to set up the plugins by setting the users you want to monitor. Edit the file /etc/munin/plugin-conf.d/munin-node

[byuser_cpu]
env.USERS "user_app1 user_app2"

[byuser_mem]
env.USERS "user_app1 user_app2"

Now you need to restart munin-node

service munin-node restart

Later check on your munin server.

Supported plugins

We recommend the following plugins:

postgres_*

To install this plugins run:

# Set up postgres_* plugins
for file in `ls /usr/share/munin/plugins/postgres_*`
  do
  ln -s $file /etc/munin/plugins
done
