Query Explanation

The rule computes the JVM heap usage percentage for each Elasticsearch instance by dividing elasticsearch_jvm_memory_used_bytes{area="heap"} by elasticsearch_jvm_memory_max_bytes{area="heap"} and multiplying by 100. The alert triggers on any instance where this calculated value exceeds 80 %, indicating a potential heap‑memory pressure situation.
