71
The monitoring of essential servers and services is an important part of system administration.
72
Most network services are monitored for performance, availability, or both. This section will cover
73
installation and configuration of <span class="application"><strong>Nagios</strong></span> for availability monitoring, and
74
<span class="application"><strong>Munin</strong></span> for performance monitoring.
77
The examples in this section will use two servers with hostnames <span class="emphasis"><em>server01</em></span> and
78
<span class="emphasis"><em>server02</em></span>. <span class="emphasis"><em>Server01</em></span> will be configured with
79
<span class="application"><strong>Nagios</strong></span> to monitor services on itself and <span class="emphasis"><em>server02</em></span>.
80
Server01 will also be setup with the <span class="application"><strong>munin</strong></span> package to gather information
81
from the network. Using the <span class="application"><strong>munin-node</strong></span> package, <span class="emphasis"><em>server02</em></span>
82
will be configured to send information to <span class="emphasis"><em>server01</em></span>.
85
Hopefully these simple examples will allow you to monitor additional servers and services on your network.
