How can I troubleshoot issues in the Elastic Stack?

I'm having trouble with my Elastic Stack setup. What are some common issues?

Common issues include Elasticsearch not starting, Kibana not connecting, and Logstash configuration errors. What specific problem are you facing?

Elasticsearch is not starting. What should I check first?

First, check the Elasticsearch logs for any error messages. You can find them in the logs directory, usually located at /var/log/elasticsearch.

I found an error about insufficient memory. How can I fix that?

You can increase the heap size in the jvm.options file. Make sure to allocate enough memory based on your system's resources.

Thanks! What if Kibana still can't connect after fixing Elasticsearch?

Ensure that Kibana is configured to connect to the correct Elasticsearch URL in the kibana.yml file. Also, check for network issues.
