These days, the company I work for has a couple dozen customers,
and it's getting impossible to regulary check all their websites for 'still up, host didn't screw up', etc.

So I'm wondering, who of you is using any kind of software, or hosted service, to monitor her (or her customers)
websites for breakdown and possibly, changes.

What I'd be looking for feature wise is of course minimal setup costs as well as the abilitiy to check a special page that
would use whatever server side language to check the database.

Any ideas?
So long,

PS: I'm trying to find such things via google, but there are apperantly a whole beach of them...
PPS: Web based interface and installation on a server are of course requirements for any solution we'd have to take care of ourselves.

I'm not clear if you're talking about servers that you have root admin or shared in different locations or what but have a look at nagios in the meantime

We have a lot of this running.
From database & processor statuses/load which requires installs on root level to simpler curl to a webapi to retrieve answers/data to check. To monitor these we use nagios that lists all the watchpoints and alerts on different levels when there is a problem.

Basic checks can also be done by scheduled curl to the site and some simple regexp, to parse for something you know should be in the beginning or end of the source of the index page.

Even if that's very basic should at least tell you if the page is rendering at all.

For more intricate functionality you could set up a SMAPI for the site that you can curl to, it can be as simple as checking a count in the database and return 1 or 0 if it has imcremented as expected.
You get the idea.

i think they have software for those things. there's a daemon for logging system usage & an inclusive logger in each daemon. apache should have a log in /var, i think.

Once the days are old, you'll never go back.

I've used Nagios and Ganglia. Nagios is a real time monitoring system. You can tie it in with a text-messaging or call system, and get notified if something goes down. Ganglia is used for historical graphing, and is great to review if something does go down.

They do take a little bit to setup initially, but are well worth it. With Nagios, one of the things you'll want to look into is Nagvis - it will lay out all of the information in a clean, easy to understand way - you will know what is up and not up.
