Resolving the "Elasticsearch is in Split-Brain Situation" Alert in Instana

Troubleshooting


Problem

When monitoring an Elasticsearch cluster, you may encounter the error message "Elasticsearch is in split-brain situation." This indicates a potential issue where two different parts of the cluster might be electing separate master nodes, resulting in a split-brain scenario. In Instana, this alert often turns out to be a false positive.

Symptom

The error message "Elasticsearch is in split-brain situation" appears in the Instana monitoring dashboard.
