## Common questions

### Which log collection agent should I use with Loki now?

Use Grafana Alloy for log collection. Alloy replaced Promtail because Promtail is considered feature complete, and future logs collection development is in Alloy.

### Will the Grafana Loki Helm chart move to a different repository?

Effective March 16, 2026, the Loki Helm chart will be forked to the grafana-community/helm-charts repository. The chart in the Loki repository will continue to be maintained only for GEL users.

### What Grafana version is needed for native Loki support?

Native support in Grafana requires Grafana v6.0.

### Do I have to store Loki log chunks in S3?

No. Loki stores compressed log chunks in object stores such as S3 or GCS, or locally on the filesystem.

### What configuration file must be placed before first start of the Unraid Loki Docker setup?

Before first start, place the local-config.yaml file in the Host Path 1 directory.
