How to delete all log data from ElasticSearch using curl?

Question

I want to delete all log data from elasticsearch node. I installed ElasticSearch on ubuntu on a Vmware workstation and nothing else. but size of vmware is growing every day. I don't know if reason of this size growing is because of elasticsearch log operation or not? if yes how can i delete all logs?

Answer 1

First make sure the issue is with the log files.

du -sch /var/log/elasticsearch

The above command would be a good place to start with. Next , make sure the logs are in control. /etc/elasticsearch/elasticsearch.yml file has the config for logging.

 file:
    type: rollingFile
    file: ${path.logs}/${cluster.name}.log
    maxFileSize: 200000
    maxBackupIndex: 10
    layout:
      type: pattern
      conversionPattern: "[%d{ISO8601}][%-5p][%-25c] %m%n"

The above configuration with maxFileSize and maxBackupIndex should keep a check on this folder size. Decrease the file size if you cant afford it.

If you want to disable logging , change this line in logging.yml

rootLogger: ${es.logger.level}, console, file

to

rootLogger: ${es.logger.level}, console
