Prometheus fake remote read storage

Remote read storage uses promtool series notation

Artifacts

• Binary releases
• Docker images

Demo

1. Clone repo and run. It starts docker compose with prometheus and fake remote-read util

   make demo
   

2. Open local prometheus (http://127.0.0.1:9090) and checkout test metric

Instalation

1. Prepare configuration (see example.config.json). Please read promtool series notation

   {
       "input_series": [
       {
           "interval": "1m",
           "series":   "test{job='backfiller_test'}",
           "values":   "0+1x100 99-1x99"
       },
       {
           "interval": "10m",
           "series":   "test{job='backfiller_test2'}",
           "values":   "0+5x100"
       }
       ]
   }
   

2. Run remote_read server

   ./prometheus-fake-remote-read --config ./your_config.json
   

3. Add remote_read address to your prometheus configuration and restart prometheus

   ...
   
   remote_read:
   - url: "http://vscode:9999/read"
   
   ...
   
   

4. For now you can query test metric. To update prometheus-fake-remote-read configuration you need to restart util. No need to restart prometheus.

Development

Run vscode with devcontainers. Prometheus and Grafana presents.
