Logstash and Filebeat not showing in stack monitoring

Hii Iam new to elk, I can't see logstash nodes and filebeat nodes in kibana stack monitoring . I can see both kibana's and elasticsearches node, could you please help me here to setup that by giving a proper doc or some suggestions

Nb:my Elasticsearch and kibana are ssl/tls enabled using certs from elasticsearch cert util

You haven't specified which LS do you have. In case of older versions <8.x, you can use collectors.

Newer version should use the Metricbeat or Elastic Agent.

My logstash version is 8.12.2, all elasticsearch kibana and logstash is in same server

I would go for MetricBeat, install, enable the logstash-xpack module... just follow the documentation.

EA is heavy, since you don't have everything, MB could be the best option.
