A small how to written to assist sys admins. It offers tools and high level advice to solve slow websites problems:
Oh boy it's been an intense 4 weeks. I was pulled in to assist with troubleshooting several major failures at work with loosely related systems. Including my own. All systems are public facing, hence the intensity.
This article attempts to capture a high level view of one of the problems and the methods and tools used (not how to use the tools, that's for another time) to try and solve it. I'm not putting all the details in. Some details are emphatically not appropriate, other details won't increase understanding of the methodology and process taken.
In the interest of helping other sysadmins, I've linked to the various tools used. Some are well known, others more obscure.
