where are elasticsearch logs stored

So I have this elastic search installation, in insert data with logstash, visualize them with kibana.

Everything in the conf file is commented, so it's using the default folders which are relative to the elastic search folder.

1/ I store data with logstash
2/ I look at them with kibana
3/ I close the instance of elastic seach, kibana and logstash
4/ I DELETE their folders
5/ I re-extract everything and reconfigure them
6/ I go into kibana and the data are still there

How is this possible?

This command will however delete the data : curl -XDELETE 'http://127.0.0.1:9200/_all'

Thanks.

  • Did you try to access Kibana from an incognito window in Chrome for example? It might be the browser's cache that is retrieved when you search for the data.
  • That's what I'm saying, I have a data folder, however kibana still display the data even after deletion of this data folder
  • On what system are you? Linux or Windows? And how did you delete the ES folder?
  • I go to the "project' folder which contains the "elasticsearch-1.7.2" folder, right clic and erase it (and yes, I stopped the elastic search instance before
  • you are right, but my problem was in fact because we were several people on the network running the same conf and our data were shared. 3 years later, I know :p
  • Yes, but the data are still present event after deletion of elastic search root directory
  • You are probably running into a cache at that point. The delete command you are sending using CURL would be the proper way to handle this.
  • This is just about curiosity, where is this cache? since I erased everything. Does it store something in appdata?
