Category Archives: Lessons learned. March 4, 2012. This really goes hand in hand with my last post, Monitoring. One thing I don’t get is why in production, most logging is shut off in my favorite PHP framework, Symfony. To me, logging is necessary to determine the state … Continue reading →. March 4, 2012.

http://zefram.net/2011/12/24/why-virtualization-is-cool

A series of lessons learned. Builds and Deployments →. Why Virtualization is cool. December 24, 2011. When developing some application or website, I cannot stress how much it helps to use virtualization. It may seem like an overcomplication, but having an exact (or nearly exact) replica of the production environment helps immensely. If I had been using a virtualization of Debian 6, I would have seen that I was developing on a version of MongoDB that was not available in my target environment. Also, you c...

March 4, 2012. What happens to your application when you’re not watching? How many people are signing up? How many are posting? Did the latest code release slow anything down? What was going on when the server crashed? These are all things that server monitoring can help you cope with. When you want to make sure that all services are working, Nagios can monitor your services and alert you when you need it. You can even add thresholds for custom metrics (there should always.
