This repository contains example configurations to support logging and metrics dashboards:

• Elastic + Logstash + Kibana (ELK) installation.
• Grafana

It also includes two Kibana dashboards, one for the Access Log activity and another for the Application Log activity.

These configurations are used in KrakenD Playground and you can test them directly.

By using the configurations included here, you will have KrakenD configured for ELK.

The logstash folder includes an example of a Logstash configuration. It parses and ingests KrakenD logs for KrakenD Enterprise and KrakenD Community Edition.

To use it, change the hostname of your Elasticsearch server and any custom ports you might use. Then, start Logstash with this configuration to properly ingest KrakenD logs.

To import the Kibana dashboard included in this repository, execute the following command once your Kibana is up and running. Replace localhost:5601 if needed:

curl -X POST "localhost:5601/api/saved_objects/_import" -H "kbn-xsrf: true" --form file=@kibana/dashboard.ndjson -H "kbn-xsrf: true"

On your krakend.json, ensure to include the telemetry/logging and telemetry/gelf components as shown below. Also, make sure the GELF address is correct.

{
  "$schema": "https://www.krakend.io/schema/v3.json",
  "version": 3,
  "extra_config": {
    "telemetry/logging": {
      "level": "DEBUG",
      "@comment": "Prefix should always be inside [] to keep the grok expression working"
      "prefix": "[KRAKEND]",
      "syslog": false,
      "stdout": true
    },
    "telemetry/gelf": {
      "address": "logstash:12201",
      "enable_tcp": false
    }
  }
}

The grafana folder includes Grafana dashboards that feed from Influx DB. Depending on your Influx version you will need to use a v1 or a v2 (Flux language) dashboard.

The dashboards are published on Grafana Cloud, and you can import them from there, but the source files are in this folder.

If you are using docker you can mount a volume using the content of this repo as follows:

  volumes:
  - "./grafana/datasources/all.yml:/etc/grafana/provisioning/datasources/all.yml"
  - "./grafana/dashboards/all.yml:/etc/grafana/provisioning/dashboards/all.yml"
  - "./grafana/krakend:/var/lib/grafana/dashboards/krakend"

In this repository, you have an example of the ingestion process and dashboard visualization, and you can improve it in many ways.

Try it out! If it doesn't help you, or you think you can add additional metrics or improvements, please open a pull request!

Thanks!
