Remote storage bridge

This is a bridge that receives samples via Prometheus's remote write protocol and stores them in Graphite, InfluxDB, or OpenTSDB. It is meant as a replacement for the built-in specific remote storage implementations that have been removed from Prometheus.

For InfluxDB, this bridge also supports reading back data through Prometheus via Prometheus's remote read protocol.

Building

go build

Running

Graphite example:

./remote_storage_bridge -graphite-address=localhost:8080

OpenTSDB example:

./remote_storage_bridge -opentsdb-url=http://localhost:8081/

InfluxDB example:

./remote_storage_bridge -influxdb-url=http://localhost:8086/ -influxdb.database=prometheus -influxdb.retention-policy=autogen

To show all flags:

./remote_storage_bridge -h

Configuring Prometheus

To configure Prometheus to send samples to this bridge, add the following to your prometheus.yml:

# Remote write configuration (for Graphite, OpenTSDB, or InfluxDB).
remote_write:
  - url: "http://localhost:9201/write"

# Remote read configuration (for InfluxDB only at the moment).
remote_read:
  - url: "http://localhost:9201/read"
