Loki-stack retention_period not working

Grafana Loki
1

Hello,

I am using Kubernetes Helm to deploy the Loki-stack. I expected that this setup would delete chunks every 24 hours, but it doesn’t seem to be working as expected. What could be the issue? Thank you.

Try disabling table manager. See Log retention | Grafana Loki documentation
