Traefik

Collect Traefik Metrics information

Installation and Configuration¶

Prerequisites¶

• Install DataKit

Traefik Configuration¶

Metrics¶

Traefik supports exposing Metrics via the Prometheus protocol by default. Add the following configuration to the Traefik configuration file:

[entryPoints]
  [entryPoints.metrics]
    address = ":9100"

[metrics]
  [metrics.prometheus]
    entryPoint = "metrics"
    buckets = [0.1, 0.3, 1.2, 5.0]

Traces¶

Traefik supports reporting trace information through the Zipkin protocol. Add the following configuration to the Traefik configuration file:

[tracing]
  serviceName= "traefik-service"
  [tracing.zipkin]
    httpEndpoint = "http://<datakit-ip>:9529/api/v2/spans"
    sameSpan = true
    id128Bit = true
    sampleRate = 1.0

Logs¶

Enable logging functionality by adding the following configuration to the Traefik configuration file, adjust level as needed:

[log]
  level = "DEBUG"
  format = "json"
  filePath = "/var/log/traefik.log"

DataKit Configuration¶

Metrics¶

To collect Traefik Metrics, navigate to the conf.d/prom directory under the DataKit installation directory and execute the following command:

cp prom.conf.sample traefik.conf

Adjust the content of traefik.conf, primarily adjusting urls, as follows:

[[inputs.prom]]
  ## Exporter URLs.
  urls = ["http://127.0.0.1:9100/metrics"]
  measurement_name = "Traefik"

Other configurations can be adjusted as needed, parameter adjustment description:

• urls: The prometheus Metrics address; here, fill in the Metrics URL exposed by the corresponding component.
• source: Collector alias, it is recommended to make distinctions.
• interval: Collection interval.

Traces¶

The DataKit collector collects Traefik trace data. Navigate to the conf.d/zipkin directory under the DataKit installation directory and execute the following command:

cp zipkin.conf.sample zipkin.conf

No adjustments are required for the content.

Logs¶

To collect Traefik logs, navigate to the conf.d/log directory under the DataKit installation directory and execute the following command:

cp log.conf.sample traefik.conf

Adjust the logfiles content in traefik.conf as follows:

[[inputs.logging]]
  ## Required
  ## File names or a pattern to tail.
  logfiles = [
    "/var/log/traefik.log",
  ]

Restart DataKit¶

After making adjustments, restart DataKit.
