elasticsearchHow can I troubleshoot an Elasticsearch cluster with a yellow status?
- First, determine which nodes in the cluster are in a yellow status. This can be done by running the following command:
GET /_cluster/healthThe output of the command will show the status of each node in the cluster.
- If the yellow status is due to a single node, then investigate the node to determine the cause of the issue. This can be done by running the following command to get the node stats:
GET /_nodes/<node_id>/stats- If the yellow status is due to multiple nodes, then check the cluster settings to make sure they are correct. This can be done by running the following command:
GET /_cluster/settings- Check the cluster logs for errors or warnings that may be related to the yellow status. This can be done by running the following command:
GET /_cluster/logs- Check the cluster state to see if there are any shards that are in an unassigned state. This can be done by running the following command:
GET /_cluster/state-
Check the network settings of the nodes in the cluster to make sure they are configured correctly.
