Receiver #

The thanos receive command implements the Prometheus Remote Write API. It builds on top of existing Prometheus TSDB and retains their usefulness while extending their functionality with long-term-storage, horizontal scalability, and downsampling. It exposes the StoreAPI so that Thanos Queriers can query received metrics in real-time. The Thanos Sidecar is not sufficient for this, as the system would always lag the block length behind (typically 2 hours).

We recommend this component to users who can only push into a Thanos due to air-gapped, or egress only environments. Please note the various pros and cons of pushing metrics.

Thanos Receive supports multi-tenancy by using labels. See Multitenancy documentation here.

For more information please check out initial design proposal. For further information on tuning Prometheus Remote Write see remote write tuning document.

Example #

thanos receive \
    --tsdb.path        "/path/to/receive/data/dir" \
    --grpc-address 0.0.0.0:10907 \
    --http-address 0.0.0.0:10909 \
    --receive.replication-factor 1 \
    --label "receive_replica=\"0\"" \
    --receive.local-endpoint 127.0.0.1:10907 \
    --receive.hashrings-file ./data/hashring.json \
    --remote-write.address 0.0.0.0:10908 &
    --objstore.config-file  "bucket.yml"

type: GCS
config:
  bucket: example-bucket
