NAME

dm_cache_occupancy_ - Wildcard-plugin to dm-cache occupancy.

CONFIGURATION

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.
