Metrics

Metrics

Traefik provides metrics in the OpenTelemetry format as well as the following vendor specific backends:

Datadog
InfluxDB2
Prometheus
StatsD

Traefik Proxy has an official Grafana dashboard for both on-premises and Kubernetes deployments.

Open Telemetry

Default protocol

The OpenTelemetry exporter will export metrics to the collector using HTTP by default to https://localhost:4318/v1/metrics.

Configuration Example

To enable the OpenTelemetry metrics:

File (YAML)

metrics:
  otlp: {}

File (TOML)

[metrics]
  [metrics.otlp]

CLI

--metrics.otlp=true

Helm Chart Values

# values.yaml
metrics:
  # Disable Prometheus (enabled by default)
  prometheus: null
  # Enable providing OTel metrics
  otlp:
    enabled: true
    http:
      enabled: true

Helm Chart Configuration

Traefik can be configured to provide metrics in the OpenTelemetry format using the Helm Chart values. To know more about the Helm Chart options, refer to the Helm Chart (Find options metrics.otlp).

Vendors

Datadog

Configuration Example

To enable the Datadog:

File (YAML)

metrics:
  datadog: {}

File (TOML)

[metrics]
  [metrics.datadog]

CLI

--metrics.datadog=true

Configuration Options

Field	Description	Default	Required
`metrics.addInternals`	Enables metrics for internal resources (e.g.: `ping@internal`).	false	No

`address`

Address instructs exporter to send metrics to datadog-agent at this address.

This address can be a Unix Domain Socket (UDS) in the following format: unix:///path/to/datadog.socket. When the prefix is set to unix, the socket type will be automatically determined. To explicitly define the socket type and avoid automatic detection, you can use the prefixes unixgram for SOCK_DGRAM (datagram sockets) and unixstream for SOCK_STREAM (stream sockets), respectively.

`metrics.prometheus.headerLabels`	Defines extra labels extracted from request headers for the `requests_total` metrics. More information here.		Yes

headerLabels

Defines the extra labels for the requests_total metrics, and for each of them, the request header containing the value for this label. If the header is not present in the request it will be added nonetheless with an empty value. The label must be a valid label name for Prometheus metrics, otherwise, the Prometheus metrics provider will fail to serve any Traefik-related metric.

How to provide the Host header value

The Host header is never present in the Header map of a request, as per go documentation says:

// For incoming requests, the Host header is promoted to the
// Request.Host field and removed from the Header map.

As a workaround, to obtain the Host of a request as a label, use instead the X-Forwarded-Host header.

Configuration Example

Here is an example of the entryPoint requests_total metric with an additional “useragent” label.

When configuring the label in Static Configuration:

Configuration

# static_configuration.yaml
metrics:
  prometheus:
    headerLabels:
      useragent: User-Agent

Request

curl -H "User-Agent: foobar" http://localhost

Metric

traefik_entrypoint_requests_total\{code="200",entrypoint="web",method="GET",protocol="http",useragent="foobar"\} 1

File (YAML)

metrics:
  statsD:
    address: localhost:8125

File (TOML)

[metrics]
  [metrics.statsD]
    address: localhost:8125

CLI

--metrics.statsd=true

Configuration Options

Field	Description	Default	Required
`metrics.addInternals`	Enables metrics for internal resources (e.g.: `ping@internals`).	false	No
`metrics.statsD.addEntryPointsLabels`	Enable metrics on entry points.	true	No
