Log Anomaly Doesn't Work?

ES/Kibana 9.1.3
I get this error:

Hello @erikg

As per the link :

Choose indices By default, Machine Learning analyzes log messages in all log indices configured for the log sources setting. You can choose to only analyze a subset of the index names. Every selected index name must match at least one index with log entries. You can also choose to only include a certain subset of datasets. Note that the dataset filter applies to all selected indices.

So in your case there is no pattern found for above 3 in the cluster.

I tried testing with sample logs & pattern is updated :

Thanks!!
