#monitoring

The gap between something that works and something you can be responsible for is not features. It is backups you have restored, deploys you can undo, logs that survive the crash, and alerts that reach a human.

If you use memcached to cache contents among different servers and apps, and you want to get statistics for what is happening inside the memcached-sever you can use one of the available interfaces for programming languages but there are simpler ways to do that.

Making Munin usable once you are monitoring more servers than you expected: a cleaner layout and the plugins worth adding.
