Thread: The Best Free Monitoring SoftWare

On Windows.. ServersAlive? (http://www.woodstone.nu/)

We use up.time, but it;s not free

Nagios, in conjunction with cacti, which we've customised to use a shared auth db and mysql for config, with a php admin frontend. Works like a dream

Beware of Internetseer... if you signup they will spam you with all sorts of rubbish.

They're hardly reliable either. I have to say the best free remotely hosted monitor I've seen is easymonitor.com, they don't spam you, are completely free of charge and always spot outages over around 15 minutes. I prefer in-house monitoring though, 15 minutes isn't acceptable for us.

Cheers for the list guys. Have checked out the list, I still like the look of hybodus - time to convince the bosses it's worth $200

Other than that, Cacti with the THold plugin (search their forums) seems quite a good free solution.

Chris.

Having tested (and paid for) hybodus for around 10 days it does seem to produce a few false alarms, which I guess other monitoring software does too, but it may be worth trialling it first (especially if your servers are further away from the monitoring box).

I wrote a simple one a while ago, but I don't think it went into production. Was a while ago now.

Sometimes, web browsers and internet connections screw up, but that doesnt mean your site is down. Assuming the others have written their software in a similar way. You ever seen an image not load, but press F5 and its back?

Well depending on how these other programmes are coded, I guess they should report some sort of error.

If you have ever seen a webpage that doesnt show its page objects until the page has completed loading, this works in a similar way. You just have to loop through the html objects, images, etc until the status is loaded, then you know your site is up. If it doesn't, you can assume something is wrong.

I will try to find the source code for it, incase anyone wants to use it or adapt it.

Regards
Andy
