Some notes from Joshua Thijssen’s talk, which focussed on the knowledge and methods needed to deal with problems in production in a measured way. I was at the back of the room, and some of this is outside my wheelhouse, but here’s the notes; just bear in mind I might have either misheard or misunderstood stuff and feel free to correct me in the comments.
Deal with the problem now. Don’t reboot. Don’t reboot your system every night on a Cron job to solve a slowdown! Listen to your problems, sort them out and save yourself some future pain.
If you’re rebooting every night to solve some system slowdown, but your visitors suddenly increase 200% then you’re now rebooting at night AND at lunchtime. Not good. Not sustainable.
