I just started working with PerfTop built-in dashboards but I’m surprised nodes are not identified by their hostnames but by an id. Where do these ids come from? And how can I match them to my known hostnames? Thanks.
Hi, the node ID is from elasticsearch. You can get it by querying “id” with the “_cat/nodes” API (https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-nodes.html).
