It's All Good

About

It's All Good is a simple service monitor framework to make it easy to monitor various services on a server.

At its core it's a light framework for checking various aspects of a server and deciding if things are operating within defined parameters or not. So far it has "out of the box" support for:

• CPU Load - As simple as it sounds. Check that your CPU load doesn't exceed a threshold you define.
• Disk Usage - Sets off an alarm when your server is running low on disk space.
• SMTP Ping - This makes a connection to your SMTP server to check that it's online and operational.
• MySQL Check - Checks to see if it can make a successful connection to a MySQL server.
• HTTP(s) Check - This can connect to a HTTP or HTTPS server and check that it connected successfully as well as check that for a condition on the page. This is handy to make sure a web app is up and running or that your SSL cert isn't expired.

Since it's just a framework, adding other checks are relatively easy. There's lots more I want to include (memory, disk IO, process monitor for example). It's designed to monitor the host, not a series of servers (though technically doable). This isn't Nagios, it's a way to get a quick glance at your key services on a host.

On its own it doesn't send any notifications. It's designed to be combined with the keyword monitoring feature of services like Pingdom, Monitis, Host-Tracker, SiteUptime, or Howsthe.com among others. This way you not only check services, but the server itself. If anything fails, you will be notified by your monitoring provider.

It's All Good also has a UI for an admin to view which can give you the status and a basic rundown of its polling data. It's also designed to so that it's pretty easy to read on mobile devices like the iPhone, making it a great dashboard for on the go.

Lastly it's designed to be pretty light and quick, so unless you are monitoring a ton of things on your server, it shouldn't have any real overhead.

So far I've only implemented real support for the checks for Linux. I suspect most will work on BSD, and Darwin (though not all). Windows still needs some help. Patches are welcome. I'd also like to support things like IP whitelist/blacklists (automated via RSS fetches), and lots of modules to extend what it can keep track of.
