Systemd configuration for rrdcached¶
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”.
