Munin

Перед установкой Munin на server01 необходимо установить веб-сервер apache2. Стандартной конфигурации будет достаточно для запуска сервера munin. Для более детальной информации по настройке apache2, обратитесь к разделу HTTPD - Apache2 Web Server.

Для начала на server01 установим munin. Введите в терминале:

sudo apt-get install munin

Теперь на server02 установим пакет munin-node:

sudo apt-get install munin-node

На server01 отредактируйте файл /etc/munin/munin.conf добавив ip адрес server02:

## First our "normal" host.
[server02]
       address 172.18.100.101

Далее настроим пакет munin-node на server02. Отредактируйте файл /etc/munin/munin-node.conf для доступа server01:

allow ^172\.18\.100\.100$

Replace ^172\.18\.100\.100$ with IP address for your munin server.

Now restart munin-node on server02 for the changes to take effect:

sudo /etc/init.d/munin-node restart

Finally, in a browser go to http://server01/munin, and you should see links to nice graphs displaying information from the standard munin-plugins for disk, network, processes, and system.

Since this is a new install it may take some time for the graphs to display anything useful. Additional Plugins

The munin-plugins-extra package contains performance checks additional services such as DNS, DHCP, Samba, etc. To install the package, from a terminal enter:

sudo apt-get install munin-plugins-extra

Be sure to install the package on both the server and node machines. References
