</div>Indeed. Plus, for active monitoring, if you can write a script to do it, Nagios can monitor it. In essence, the monitoring side of Nagios is just calling scripts and processing the response code (OK, Warning, Critical, Unknown). So pretty well all you need to do is write a script (optionally taking some parameters), and have it spit out a one-line result - whatever goes inside is up to you and can be as simple or complex as you like/need/can cope with.<br>
<br>
Though I have to agree with an easrlier comment - it's a bit heavyweight, and has a fairly steep learning curve until you get your head round it.<br>
