Metricbeat, with its 7.2 release, has expanded its capabilities to report metrics on Linux software RAID, providing detailed insights into RAID devices created with mdadm. These devices offer various metric interfaces, including ioctl, /proc/mdstat, and the /sys/block/mdX sysfs interface, with Metricbeat utilizing the latter for data collection. To begin monitoring, users need to enable the RAID metricset in Metricbeat's system module configuration and ensure proper setup if running within Docker. Once configured, Metricbeat categorizes disk states into active, total, spare, and failed, and reports these to Elasticsearch, allowing users to identify issues like failed disks using Kibana's Discover app. This integration offers a straightforward approach to monitoring Linux software RAIDs using the Elastic Stack, with support available through a free trial or community forums.
