Troubleshooting Steps
N/A
Cause
There was a change to the `logback.xml` configuration file introduced in Dremio 20.0 and later versions, as described in the release notes: https://docs.dremio.com/software/release-notes/200-release/#breaking-change
Steps to Resolve
1. Download the new `logback.xml` from the Dremio repository: https://github.com/dremio/dremio-cloud-tools/blob/master/charts/dremio_v2/config/logback.xml
2. Rebuild your `ConfigMap` to include the new `logback.xml`. If you are using Helm with the Dremio charts, replace the old `logback.xml` with the new one in the `config` directory and upgrade the Dremio release.
**Note:** If you are running an older release of Dremio and use the v20.x version of the `logback.xml`, you may also experience problems with missing entries.
