Upstart configuration for rrdcachedΒΆ

This example sets up a dedicated rrdcached instance for munin.

If rrdcached stops, it is restarted.

A pre-start script ensures we have the needed directories

A post-start script adds permissions for the munin fastcgi process. This assumes that your fastcgi graph process is running as the user “www-data”, and that the file system is mounted with “acl”.
