Effective troubleshooting with Grafana Loki - query basics

Loki doesn't index your logs, and that is a very different approach than popular full-text search engines like Elasticsearch or Solr

That sounds like a huge constraint. How can you do powerful searches if you don't index the log lines?

After this video, you now know how to use Loki's "filter" capability for forensic troubleshooting. Happy searching!

Thanks for making this video. I was wondering about the log labels shown at 1:39 such as filename, pod and pod_template_hash. Don't they pose a cardinality problem for Loki?

And what performance should I expect, I I want to fetch all logs with some specific `traceId` ?
I guess in such case Loki will need to parse all 10s of gigabytes of my logs, and will be definitely slow
