We are facing issue with Elasticsearch Java client but we are not getting any error in Elasticsearch data/master node log. I have updated logger level from INFO to DEBUG but I don’t think it will help. Do you have any suggestions to capture Java client failure details in Elasticsearch log?
PUT /_cluster/settings
{
"persistent": {
"logger.org.elasticsearch.discovery": "DEBUG"
}
}
>Solution :
By definition, the Java client runs on the client side and by modifying the log level of the ES server, you’re only influencing how the ES server-side logs are generated.
If you want to investigate client-side logs, you need to act directly on your client Java application where you can configure the logging settings easily.
