Configuration

Configuration options · from collectd.conf(5)

See this section in the full configuration reference

The md plugin collects information from Linux Software-RAID devices (md).

All reported values are of the type md_disks. Reported type instances are active, failed (present but not operational), spare (hot stand-by) and missing (physically absent) disks.

Device Device

Select md devices based on device name. The device name is the basename of the device, i.e. the name of the block device without the leading /dev/. See IgnoreSelected for more details.

See /"IGNORELISTS" for details.

IgnoreSelected true|false
Invert device selection: If set to true, all md devices except those listed using Device are collected. If false (the default), only those listed are collected. If no configuration is given, the md plugin will collect data from all md devices.
