What is this?

A simple hacky script + tool to download chunks from ingesters and dump their content.

How to use it

1. Edit pkg/ingester/client/ingester.proto and change the import "github.com/grafana/mimir/pkg/mimirpb/mimir.proto" statement to import "pkg/mimirpb/mimir.proto"
2. Edit download-chunks-from-ingesters-query.json with the label matchers and time range to query.
3. Edit download-chunks-from-ingesters.sh with the configuration about the Kubernetes namespace and Mimir tenant to query.
4. Run bash ./download-chunks-from-ingesters.sh from this directory to download the chunks.
5. Once you've got the dump (1 file per ingester), run go run . chunks-dump/* to print the dump content of 1+ files.
