Free Server Monitoring Service or Software

Question

Looking for a free service, or software to monitor 2 websites, one is hosted on a linux machine, and the other a windows machine (though, shouldn't really matter).

Any suggestions?

Answer 1

A free external option: http://mon.itor.us/

Answer 2

Nagios is a pretty nice open source solution for system monitoring if you have a *nix server to put it on. The configuration takes a little time to learn, but pays off if you want something that's very flexible and full featured.

Answer 3

Lots of threads already on Stack Overflow about this, like this one:

http://stackoverflow.com/questions/276180/server-monitoring-and-alerting-software

You also have the necessary rep to take part in the Server Fault beta which would be a really good place for this question.

Edit: there's a thread currently on the first page of Server Fault that you may find useful: http://serverfault.com/questions/44/what-tool-do-you-use-to-monitor-your-servers

Answer 4

I use http://www.nagios.org/ for real time monitoring. I love it and it has saved my bum many many times.

I just tried the free version of splunk.com for historical monitoring. I can't really rate it yet since I've only used it for one day.

Answer 5

Munin is an alternative to nagios, simpler but easier to learn and set up.

Answer 6

Another good tool is monit. You can write scripts for it, almost in English grammar.

Answer 7

You didn't specify what kind of monitoring you want.

If you want just availability checks, these tools/services mentioned before are ok. If you want integrity checks too (be notified when your site changes), I will suggest the free service that I am working on, Sucuri NBIM (Network-based integrity monitor). Link:

*It also does monitoring of other resources, like whois changes, dns, etc.. **just a little biased :)

Thanks,
