To find out which agent has not sent logs

[hadi_farzipour]

I have 1000 agents sending their logs to my ELK stack like following lines every 10 seconds

{
  "_index": "my_logs",
  "@timestamp": "2022-08-31T08:11:21.622Z",
  "agent_name":"agent_1",
  "size" : 15
}

I know a way to list my all agents has successfully sent their logs, how ever I need to visualize which agents haven't sent their logs yet.
, is there any way to visualize which agents have not sent their logs on Kibana.
I currently use Kibana 7.6.1 and Elasticsearch 7.6.1

Elasticsearch 7.6 is EOL and no longer supported. Please upgrade ASAP.
