Preconfigured Grafana dashboard

The Grafana dashboard for KrakenD offers valuable information to understand the performance of your services and detect anomalies in the service.

The dashboard is extensive and offers you metrics like:

  • Requests from users to KrakenD
  • Requests from KrakenD to your backends
  • Response times
  • Memory usage and details
  • Endpoints and status codes
  • Heatmaps
  • Open connections
  • Throughput
  • Distributions, timers, garbage collection and a long etcetera

Configure Grafana

Add the following configuration to your krakend.json at the root level:

{
  "version": 2,
  "extra_config": {
    "github_com/letgoapp/krakend-influx":{
        "address":"http://192.168.99.9:8086",
        "ttl":"25s",
        "buffer_size":0
    },
    "github_com/devopsfaith/krakend-metrics": {
      "collection_time": "30s",
      "listen_address": "127.0.0.1:8090"
    }
  }
}

For more details of this configuration see the InfluxDb exporter

Then, import our Grafana dashboard for Krakend.

  -e INFLUXDB_USER=letgo -e INFLUXDB_USER_PASSWORD=pas5w0rd \ 
  -e INFLUXDB_ADMIN_USER=admin -e INFLUXDB_ADMIN_PASSWORD=supersecretpassword \ 
  -it --name=influx \ 
  influxdb 
  1. Open the CLI:
