Remote storage adapter

This is a write adapter 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 binary is also a read adapter that supports reading back data through Prometheus via Prometheus's remote read protocol.

Building

go build

Running

Graphite example:

./remote_storage_adapter --graphite-address=localhost:8080

OpenTSDB example:

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

InfluxDB example:

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

To show all flags:

./remote_storage_adapter -h

Configuring Prometheus

To configure Prometheus to send samples to this binary, 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"
