# prometheus-query-proxy

This works as a reverse proxy in front of multiple Prometheus.

## Installation

```

go get github.com/ryotarai/prometheus-query-proxy

```

## Configuration

```yaml

datasources:

- url: "http://localhost:9090"

  resolution: '15s' # a.k.a. scrape interval

  retention: '360h' # optional

- url: "http://localhost:9091"

  resolution: '1m' # a.k.a. scrape interval

  retention: '1440h' # optional

```

## Endpoints

### `/api/v1/query_range`

A datasource is picked up based on:

```

(Time of now) - (Datasource retention) <= ("start" query param)

  AND (Datasource resolution) <= ("step" query param)

```

If there are multiple datasources, this selects a datasource whose resolution is the shortest.

### `/api/v1/query`

A datasource is picked up based on:

```

(Time of now) - (Datasource retention) <= ("time" query param)

```

If there are multiple datasources, this selects a datasource whose resolution is the shortest.

### `/api/v1/label/KEY/values`

This requests to all datasources and merge them into one response.
