I've installed filebeat in a server, collecting all the logs from all the containers i have. With filebeat i indicate to which elasticsearch and kibana hosts he must send them (both, elasticsearch and kibana are running as a service in another server). So now all the logs appear in kibana. My question is, all those logs that appear there, are stored somewhere? In elasticsearch or in kibana?
Thank you in advance
All the data is stored inside Elasticsearch.
Kibana is a visualization engine on top of Elasticsearch. Kibana itself also stores its configuration data inside an internal Elasticsearch index called .kibana
.
Whatever you can see from Kibana always comes from Elasticsearch.
You can learn more about Elasticsearch here and Kibana here.
