What's the best free web app for monitoring multiple websites?
May 12, 2009 7:25 AM   Subscribe

What's a good, easily installed open-source web app for monitoring multiple web servers? I used to be a network admin and most of the tools I used for that racket seem way overkill for what I want to do here. Basically I just want to get alerts if a site goes down, and track some analytics of server uptime so I can complain to ISPs with some evidence to back me up.

PHP would be nice, since that'll run anywhere, with I figure a cron job that polls the servers at regular intervals? Thanks

Xymon, formerly Hobbit (ahh, trademark issues....) Not trivial to install, but not hard for basic setups, and very good.

I can think of Munin, I only used it once, but it may be the thing you are looking for. It was relatively straightforward to set up.

From the Munin website:
Using Munin you can easily monitor the performance of your computers, networks, SANs, applications, weather measurements and whatever comes to mind. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity-wise on any resources.

Does it have to be something you run yourself? Perhaps http://aremysitesup.com/ will do what you need?

There's a paid membership, and I haven't used it, so I'm not sure what the differences are - but hopefully it will do what you need.

Mon will do your alerting for you.
Cacti will probably do all you need with graphs and whatnot.

I use SiteUptime. You can track a single website for free, 3 for $5/month and 6 for $10/month. Seemed pretty reasonable to me.

The benefits of outsourcing this are that

a) If your whole network goes down, so will your network monitoring software (so how will it reach out to you?)

b) If you have it on a separate network and that network goes down... you get the idea.

c) If the monitoring service can't connect, how do you know it's not something between the two networks?

I've had good success with the Alertra service, but if you don't need the above, then it may be overkill for you.

Last time I checked there's a 1 month trial.
