Interesting discovery of the evening: the third-party Apache module "mod_macro", packaged as libapache2-mod-macro for Debian. Awesome.

Munin Apache uptime plugin

At work, we have a customer who are having problems with their web server. So many problems, in fact, that I felt the need to write a Munin plugin to graph the uptime of Apache, so that I could tell when it had been restarted. The graphs are as boring as the code, which is entirely stolen from Munin's 'apache_volume' and 'uptime' plugins.
