Server Monitoring Software

[Xenoxide]

Hi guys,

We have a small cluster of machines at work that will be deployed soon, and I'm looking to get some opinions on what to use for server monitoring.

There's around 20 Linux machines total, and will need to see things like CPU/memory usage, disk usage, load average, network throughput, etc. We'll need to be able to generate graphs and reports, but also look at the metrics in real time. It would also be handy if there was an API we could use to built our own apps to display the data (ie. On a large screen in the office).

I've previously used GFI Server Monitor for some basic tasks, but I don't think it will fulfil most of my needs now. Does anyone have any recommendations?

Cheers.

Cheers for all the suggestions!

PRTG looks like my favourite option so far, but the open-source aspect of Zenoss is very alluring. I think I'll be giving PRTG, Nagios, and Zenoss a shot tomorrow.

Sorry to dig up an old thread, but I thought I'd update you guys on what we ended up using.

In the end I tried PRTG, Zenoss, and Nagios, and got on far better with PRTG than the others. Super simple installation and setup, and the UI is really intuitive. Does everything we need (And a stupid amount more!).

The only downside I saw is that it only runs on Windows based machines, but as we had a few spare licenses lying around, it wasn't a problem. PRTG itself wasn't expensive either considering we need less than 100 sensors at the moment.
