Grafana unable to recognize log level in 'logs volume' panel


When I “explore” my elasticsearch logs, I see the “logs volume” panel with graph. Although my logs (info, warning, error) are properly “colorized” in the bottom panel, the “logs volume” panel is unable interpret the log entries. All of them are displayed in “grey” color and the label says “unknown”.


I have configured the “level field name” field in the datasource settings, but with no luck.

My grafana version is 10.1.5

Any idea what am I doing wrong?

Thank you,

We got same problem.

The problem occurred when we upgrade Grafana from 9 to 10
