Traefik
StackState Self-hosted v4.5.x
This page describes StackState v4.5.x. The StackState 4.5 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.5 version range to upgrade to a more recent release.
The StackState Agent V2 Traefik integration provides the following functionality:
- Reporting Traefik frontends and backends as topology elements.
- Reporting all network connections between services, including network traffic telemetry.
The StackState Traefik integration is included in the Agent V2 StackPack. Currently this integration supports tracing of Traefik requests using the Datadog tracing backend supported by Traefik.
Configure your Traefik instance to report Datadog tracing data to the StackState Agent. Your Traefik.toml configuration file must include the following parameters:
# Tracing definition
[tracing]
# Use the Datadog backend to send the Datadog Tracing format to StackState Agent
backend = "datadog"
# Component name used for your Traefik instance in StackState
serviceName = "traefik"
# Span name limit allows for name truncation in case of very long Frontend/Backend names
# This can prevent certain tracing providers to drop traces that exceed their length limits
spanNameLimit = 100
[tracing.datadog]
# StackState Agent Host Port instructs reporter to send spans to the StackState Agent at this address
localAgentHostPort = "agentHost:8126"
# Applies a shared tag in a form of source:traefik to all the spans of the trace
globalTag = "source:traefik"
When using Traefik in conjunction with one of our language specific trace clients, eg. StackState Java Trace Client - Java APM it is important to note that you should use the
backend name of your Traefik service as the service-name for the trace client to allow automatic merging of the service components within StackState.Eg. for the following
Traefik.toml:...
[frontends]
[frontends.stackstate-demo-frontend]
backend = "stackstate-demo-backend"
[frontends.stackstate-demo-frontend.routes.test_1]
rule = "Host:test.stackstate-demo-backend.localhost"
[backends]
[[backends.stackstate-demo-backend]]
# ...
[[backends.stackstate-demo-backend].servers.server1]
url = "..."
...
...
you should pass the following jvm argument when starting your java application:
-Dsts.service.name=stackstate-demo-backendor for a similar docker-compose configuration:
stackstate-demo-app:
image: stackstate-demo-app:latest
pid: "host" # use pid:"host" to ensure pid's match with processes reported by the StackState process agent
ports:
- '8081-8091:8081'
depends_on:
- another_app
- stackstate-agent
labels:
- "traefik.frontend.rule=Host:stackstate-demo-app.docker.localhost"
- "traefik.backend=stackstate-demo-app"
environment:
MAVEN_OPTS: |
-Dsts.service.name=stackstate-demo-app
-Dsts.agent.host=${DOCKER_HOST_IP}
-Dsts.agent.port=8126
-javaagent:/sts-java-agent.jar
To verify whether the StackState Trace Agent has received traces, set the logging level to debug and check the
trace-agent.log:stackstate.yaml
log_level: debug
In Docker or Kubernetes, set the following environment variable for the StackState Agent
STS_LOG_LEVEL: "DEBUG"
