This is a plugin for Datadog that checks the status of Linux software RAID Multiple Device md(4) arrays and returns a variety of gauges.

The information is inelegantly parsed from /proc/mdstat and sent to datadog as various metrics.

• md_device.disk.total The total number of disks that are supposed to be active in the array.
• md_device.disk.active The number of disks that are active in the array. i.e. non-failed and non-spare. Disks that are considered recovering will be included in this count.
• md_device.disk.spare The number of spare disks in the array.
• md_device.disk.failed The number of failed disks in the array.
• md_device.disk.up The total number of fully functioning disks in the array. i.e. non-failed, non-spare and non-recovering.
• md_device.recovery.complete The percentage of recovery completed. Will return 100% for arrays that are not in recovery status.
• md_device.recovery.speed_bytes The speed of recovery. Will return 0 for arrays that are not in recovery status.
