We have some guides that can help you set up a guide in case you need to guide one quickly. The ELK stack is an open source platform used to describe a stack that comprises of three popular open-source projects: Elasticsearch, Logstash, and Kibana. In addition, without a queuing system it becomes almost impossible to upgrade the Elasticsearch cluster because there is no way to store data during critical cluster upgrades. This chart will install a daemonset that will start a fluent-bit pod on each node. Again, if we check the logs of the new Pod, we should see that it has successfully connected to the Elasticsearch instance and is now hosting the web UI on port 5601. Backfilling log messages that are held on disk creates a property of eventual consistency with your logs, which is far superior to large gaps in important information, such as audit data. After setting up a Kubernetes cluster in the cloud or local environment, you will need to check what is happening in the warehouse in an easy and flexible way.
