Elasticsearch version from Kibana-CodePudding

I have access to Kibana version 7.3

From this GUI is there a way I can confirm which elasticsearch version it is on? I cannot assume that both components are running the same version.

See question above.

CodePudding user response：

you can simply run GET / from the dev-tools of kibana and it will show you the Elasticsearch cluster details. This is same as hitting the Elasticsearch from browser when you know the Elasticsearch host and port number, response will look like

{
"name": "Elasticsearch-cluster",
"cluster_name": "es_8.1.3",
"cluster_uuid": "-Z7M-1jiRqiRcy_0HnlBUA",
"version": {
"number": "8.1.3",
"build_flavor": "default",
"build_type": "tar",
"build_hash": "39afaa3c0fe7db4869a161985e240bd7182d7a07",
"build_date": "2022-04-19T08:13:25.444693396Z",

You can use the following API to get all nodes versions

GET _cat/nodes?v&h=ip,name,version,name,jdk

the output will be like the following picture
