Hi All,

Is there any api to print elastic search node heap percentage along with cluster name?

You can find all the information you need here: Nodes stats API | Elasticsearch Guide [8.11] | Elastic

If you want to execute this API from terminal you can use this snippet to get only the information you need:

curl -XGET "http://localhost:9200/_nodes/stats" | jq '.nodes | {hostname:.name, OSMemoryUsage:(.os.mem.used_in_bytes/.os.mem.total_in_bytes)} '

curl -XGET "http://localhost:9200/_nodes/stats" | jq '.nodes | {hostname:.name, heapPercent:.jvm.mem.heap_used_percent}'
