Monitor Type: traefik (Source)
Accepts Endpoints: Yes
Multiple Instances Allowed: Yes
Traefik is an open-source HTTP reverse proxy and load balancer. Traefik exports Prometheus metrics that can be
scraped by the SignalFx Smart Agent. These metrics can be categorized into Traefik-related, entrypoint-related and
backend-related metrics. The Traefik-related metrics are prefixed by go_ and process_. The entrypoint-related
metrics are prefixed by traefik_entrypoint_ and the backend-related metrics prefixed by traefik_backend_.
The Traefik-related metrics are for monitoring Traefik itself. For instance, the go_memstats_sys_bytes metric can
be used to plot Traefik memory usage. The entrypoint-related and backend-related metrics are the number and duration
of requests measured at entrypoints and backends. These metrics are used to compute measurements such as the average
request duration.

Edit the Traefik configuration file, typically traefik.toml, to enable Traefik to expose prometheus metrics at an
endpoint. The endpoint is on path /metrics by default. When running the Traefik binary, the configuration file is
typically passed in as a command line argument. For example,
./traefik -c traefik.toml
However, when running the Traefik Docker image, the configuration file is mounted to volume
/etc/traefik/traefik.toml. For example,
docker run -d -p 8080:8080 -p 80:80 -v $PWD/traefik.toml:/etc/traefik/traefik.toml
If the Traefik configuration file is not available use the sample configuration file here to get started.
See here for complete Traefik docs.
SignalFx Smart Agent docs can be found here. Choose deployment specific configuration instruction here. The SignalFx Smart Agent must have network access to Traefik.
Below is an example configuration that enables the traefik monitor. For the given configuration below, the monitor
will scrape Prometheus metrics in the default path /metrics on port 8080, add dimension
metric_source=traefik to the metrics and export them to SignalFx.
monitors:
- type: traefik
discoveryRule: port == 8080
extraDimensions:
metric_source: traefik
To activate this monitor in the Smart Agent, add the following to your agent config:
monitors: # All monitor config goes under this key
- type: traefik
... # Additional config
For a list of monitor options that are common to all monitors, see Common Configuration.
| Config option | Required | Type | Description |
|---|---|---|---|
httpTimeout |
no | int64 |
HTTP timeout duration for both read and writes. This should be a duration string that is accepted by https://golang.org/pkg/time/#ParseDuration (default: 10s) |
username |
no | string |
Basic Auth username to use on each request, if any. |
password |
no | string |
Basic Auth password to use on each request, if any. |
useHTTPS |
no | bool |
If true, the agent will connect to the server using HTTPS instead of plain HTTP. (default: false) |
httpHeaders |
no | map of strings |
A map of HTTP header names to values. Comma separated multiple values for the same message-header is supported. |
skipVerify |
no | bool |
If useHTTPS is true and this option is also true, the exporter's TLS cert will not be verified. (default: false) |
caCertPath |
no | string |
Path to the CA cert that has signed the TLS cert, unnecessary if skipVerify is set to false. |
clientCertPath |
no | string |
Path to the client TLS cert to use for TLS required connections |
clientKeyPath |
no | string |
Path to the client TLS key to use for TLS required connections |
host |
yes | string |
Host of the exporter |
port |
yes | integer |
Port of the exporter |
useServiceAccount |
no | bool |
Use pod service account to authenticate. (default: false) |
metricPath |
no | string |
Path to the metrics endpoint on the exporter server, usually /metrics (the default). (default: /metrics) |
sendAllMetrics |
no | bool |
Send all the metrics that come out of the Prometheus exporter without any filtering. This option has no effect when using the prometheus exporter monitor directly since there is no built-in filtering, only when embedding it in other monitors. (default: false) |
These are the metrics available for this monitor. Metrics that are categorized as container/host (default) are in bold and italics in the list below.

To emit metrics that are not default, you can add those metrics in the
generic monitor-level extraMetrics config option. Metrics that are derived
from specific configuration options that do not appear in the above list of
metrics do not need to be added to extraMetrics.
To see a list of metrics that will be emitted you can run agent-status monitors after configuring this monitor in a running agent instance.
