This page address common issues when getting started and using Explore Logs.

Ensure Loki is properly configured

To use Explore Logs, you need to have Loki properly configured. You can find full instructions on how to do this when installing Explore Logs.

There are no services

If everything is presented as an unknown_service when you access Explore Logs, you can try the following fixes:

Ensure the Volume API is enabled by setting the volume_enabled configuration value in Loki. Enabled by default in Loki 3.1 and later.
Specify the label to use to identify services by setting the discover_service_name configuration value in Loki.

There are no detected levels

If you do not see detected_level values in Explore Logs, you can try the following fixes:

Ensure level detection is enabled by setting the discover_log_levels configuration value. Enabled by default in Loki 3.1 and later.

There are no labels

If you do not see any labels in Explore Logs, you can try the following fixes:

Ensure your collector is properly configured to attach them.

To learn more about Labels, refer to the Loki labels documentation.

There are no patterns

Patterns are ephemeral and will only be available for the previous three hours.

If you aren’t getting any patterns, you can try the following fixes:

Ensure pattern extraction is enabled by setting --pattern-ingester.enabled=true in your Loki config. Learn about other necessary config.
It is possible that no patterns were detected, although this is rare - please open an issue on GitHub or get in touch privately so we can see what’s going on.
