Logstash

The Logstash integration prints KrakenD application logs in JSON format (not access logs) to ingest them and process them later. If you want to log using the Logstash standard via stdout, you need to add the telemetry/logging integration as a dependency.

Configuration

The configuration you need to enable logstash is:

{
    "version": 3,
    "extra_config": {
        "telemetry/logging": {
            "level": "INFO",
            "prefix": "[KRAKEND]",
            "syslog": false,
            "stdout": true,
            "format": "logstash"
        }
    }
}

When the format of the logging format is logstash then the output of the application log (not the access log) is printed in JSON format, as follows:

{"@timestamp":"2022-06-15T15:37:02.619+00:00", "@version": 1, "level": "DEBUG", "message": "[SERVICE: Gin] Debug enabled", "module": "KRAKEND"}
{"@timestamp":"2022-06-15T15:37:02.619+00:00", "@version": 1, "level": "INFO", "message": "Starting the KrakenD instance", "module": "KRAKEND"}
{"@timestamp":"2022-06-15T15:37:02.619+00:00", "@version": 1, "level": "DEBUG", "message": "[ENDPOINT: /test] Building the proxy pipe", "module": "KRAKEND"}
{"@timestamp":"2022-06-15T15:37:02.619+00:00", "@version": 1, "level": "DEBUG", "message": "[BACKEND: /404] Building the backend pipe", "module": "KRAKEND"}

The application access log will still show in plain text. For example, you might see the application logs in JSON and the application logs in JSON. For example:

{"@timestamp":"2022-06-15T15:37:07.619+00:00", "@version": 1, "level": "DEBUG", "message": "[SERVICE: Telemetry] Registering usage stats for Cluster ID GH9V15Rf22Zp3F4HBtvF9NkGO9WL7HKp8h7St7l+qc0=", "module": "KRAKEND"}
[GIN] 2022/06/15 - 15:38:58 | 200 |       4.529µs |      172.17.0.1 | GET      "/test/access"

If you don’t want to parse the access log on Logstash, you can remove it from the stdout using disable_access_log (see how to remove requests from logs options).
