Native InfluxDB exporter

KrakenD can expose very detailed metrics to provide a monitoring dashboard. One of the richest monitoring solutions at the metrics level is the combination of krakend-metrics with the native krakend-influx exporter. The two components let you send detailed metrics to InfluxDB and draw them later on our preconfigured Grafana dashboard can feed from here and provide you a useful.

Notice that there are two different implementations of InfluxDB in KrakenD:

• Native InfluxDB exporter (this page)
• OpenCensus InfluxDB exporter

InfluxDB configuration

Pushing data to InfluxDB requires adding two different configuration pieces:

• Enabling the extended metrics (collecting the information)
• Enabling InfluxDB (pushing the data)

You can accomplish it with the following snippet.

{
    "version": 3,
    "extra_config": {
      "telemetry/influx":{
          "address":"http://192.168.99.9:8086",
          "ttl":"25s",
          "buffer_size":0,
          "db": "krakend",
          "username": "your-influxdb-user",
          "password": "your-influxdb-password"
      },
      "telemetry/metrics": {
        "collection_time": "30s",
        "listen_address": "127.0.0.1:8090"
      }
    }
}

• address (string): The complete url of the influxdb including the port if different from defaults in http/https
• ttl (duration): Valid time units are: ns (nanoseconds), us or µs (microseconds), ms (milliseconds), s (seconds), m (minutes - don’t!), h (hours - don’t!)
• buffer_size (integer): Use 0 to send events immediately or set the number of points that should be sent together.
• db (string): Name of the database, defaults to krakend.
• username and password are optional and used to authenticate against InfluxDB.

Now you are ready to publish a Grafana dashboard.
