Troubleshooting

April 6, 2008 | mark | Scaling

It’s funny how when you’re troubleshooting a performance issue on your servers that suddenly made the load average spike to 14 (350% with four CPU cores) at 6:30am on a Sunday morning (yay!) all the stats look like garbage until you figure out what it is and then it’s so glaringly obvious that you spend the rest of the day kicking yourself for not seeing it immediately.

Note to self: Next time make coffee, drink coffee, and only then log on to munin to troubleshoot.

My name is Mark Maunder. I've been blogging since around 2003 when I started on Movable Type and ended up on WordPress which is what I use to publish today. With my wife Kerry, I'm the co-founder of Wordfence which protects over 5 million WordPress sites from hackers and is run by a talented team of 36 people. I'm an instrument rated pilot and I fly a Cessna 206 along with a 1964 Cessna 172 in the Pacific Northwest and Colorado. I'm originally from Cape Town, South Africa but live in the US these days. I code in a bunch of languages and am quite excited about our emerging AI overlords and how they're going to be putting us to work for them.
