Grafana Phlare querier

In March 2023, Grafana Labs acquired Pyroscope, the company behind the eponymous open source continuous profiling project. As a result, the Pyroscope and Grafana Phlare projects will be merged under the new name Grafana Pyroscope. To learn more, read our recent blog post about the news.

The querier is a stateless component that evaluates queries expressions by fetching profiles series and labels on the read path.

The querier uses the ingester component only to query recently written data. The support of querying the long-term storage is planned for the next release.

Connecting to ingesters

You must configure the querier with the same -ingester.ring.* flags (or their respective YAML configuration parameters) that you use to configure the ingesters so that the querier can access the ingester hash ring and discover the addresses of the ingesters.
