Wordpress like many web applications relies on apache (or something else) to serve the HTTP pages and mysql to store the data. Your wordpress website is important to you, so you need an external monitoring system to let you know what’s going on.

Nagios is a great, enterprise class, open-source monitoring application; and what you need do is configure it to exactly represent how wordpress works; if you can get that right you can immediately get notified if any piece of the puzzle fails.

Recently I decided to re-organise my bookmarks toolbar, and added links to my nagios and cacti installations. I noticed that the favicons where missing.

For cacti, there’s a how to, but I found it a little over kill - I didn’t need step 2 , as my catci install is an rpm from dag, and I didn’t bother with step 4, as it worked without it, but hey ymmv!

Nagios was simpler, depending on how you installed nagios, will effect file permission , owners, directories etc. Again, I’ve got another dag rpm, so for me I logged in as root,

Been looking for something like this for a while…..

Nagios Checker | Firefox Add-ons | Mozilla Corporation
The statusbar indicator of the events from the network monitoring system Nagios. Information is parsed from Nagios web interface. In the extension settings dialog simply fill the start page URL of your Nagios web interface, eg. http://www.yourfirm.com/nagios/ and let the button to locate status script url.

I’ve received a patch from ed.davison, if you have commented out hosts in your config, you’ll get odd \”address - hostname\” results in the drop down list. Ed’s patch fixes that; thankx

At the moment you’d have to apply the patch your self from the below; but I have a official revision in the pipeline.

Recently I had a request from rex to modify my nagios ping tool (Official Nagios Exchange page); he wanted to use the tool with his nagios configuration.

Rex appeared to be using Nagios QL (Which I believe to be a nagios management tool) , now QL handles nagios config slightly differently . The Ping Tool reads the nagios hosts.cfg file, and turns it into a couple of arrays to use for ping & display, with QL they generate multiple hosts.cfg files, one for each hosts.

Perhaps a short way of saying it, Rex needed to read in multiple hosts.cfg files from a directory, and below is the hack to do it

Another day, another mini project.

My place of work pretty much demanded the need for our monitoring guys (i.e. people that stare at the nagios screen, waiting for red things) to have the ability to run traceroutes from nagios to the effected node - The twist in the story was that they wanted to do it from a browser !

So, I thought, that’d be an easy php script then , well to be honest it took a little longer than expected, mainly because I don’t really understand regular expressions (yet).

Nagios-ping-tool Is a package of small scripts :

.. or nagios is great, I use it a lot.

In my continuing quest to cure command line phobia I’ve written a small (& Basic) php script that can generate some sample configs. Simply type in the IP of what you want to monitor , tick a couple of boxes, and copy & paste what you get into the end of your config files - nice
