dm_cache_occupancy_ - Wildcard-plugin to dm-cache occupancy.
This plugin does not normally require configuration.
The plugin may need to run as root to determine dm-cache status. This is configured like this:
[dm_cache_*] user root
This is a wildcard plugin. To monitor a cached device-mapper volume, link volume to this file. For example,
ln -s /usr/share/munin/plugins/dm_cache_occupancy_ \ /etc/munin/plugins/dm_cache_occupancy_vg_1122____lv_home
will monitor vg_1122-lv_home.
Please note that ____ (4 underscores) is replaced by - (dash) symbol. This is workaround for http://munin-monitoring.org/ticket/1236
Cached volumes found in dmsetup status can be monitored.
