Setting up the ELK Stack, which includes Elasticsearch, Logstash, and Kibana, can be straightforward, but users often encounter common issues that are generally easy to resolve. The text outlines five prevalent problems and provides troubleshooting steps for each. If Kibana is unable to connect to Elasticsearch, it often requires verifying the server IP and host configuration in Kibana's settings. When Kibana cannot fetch mapping, the issue may lie in the index pattern or the data not being properly forwarded by Logstash. Logstash not running or failing to ship data frequently points to configuration errors, which can be checked using the configtest parameter and examining Logstash logs. If Elasticsearch is not running, checking the Elasticsearch logs can help identify issues such as incorrect host configurations or service startup problems. The article provides a comprehensive guide for newcomers to troubleshoot and resolve these basic setup issues effectively.
