Query Explanation

The rule computes the free‑disk percentage for each Elasticsearch data volume as elasticsearch_filesystem_data_available_bytes / elasticsearch_filesystem_data_size_bytes * 100 and checks if it is < 10 %. The alert triggers when any node has less than 10 % free space, i.e., when disk usage is over 90 %.
