Datadog APM agent

An agent that collects traces from various sources, normalizes and pre-processes them before sending the info to the Datadog backend.

Run on Linux

The Trace Agent is packaged with the standard Datadog Agent. Just run the Datadog Agent.

Run on OSX

The APM agent (aka Trace Agent) isn't part of the OSX Datadog Agent yet, it needs to be run manually on the side.

Have the OSX Datadog Agent.
Download the latest OSX Trace Agent release.
Run the Trace Agent using the Datadog Agent configuration.

./trace-agent-osx-X.Y.Z -ddconfig /opt/datadog-agent/etc/datadog.conf
The Trace Agent should now be running in foreground, with an initial output similar to:

2017-04-24 13:46:35 INFO (main.go:166) - using configuration from /opt/datadog-agent/etc/datadog.conf
2017-04-24 13:46:36 INFO (agent.go:200) - Failed to parse hostname from dd-agent config
2017-04-24 13:46:36 DEBUG (agent.go:288) - No aggregator configuration, using defaults
2017-04-24 13:46:36 INFO (main.go:220) - trace-agent running on host My-MacBook-Pro.local
2017-04-24 13:46:36 INFO (receiver.go:137) - listening for traces at http://localhost:8126

Development

Pre-requisites:

go 1.7+
rake

Hacking:

Import dependencies with rake restore. This task uses glide to import all dependencies listed in glide.yaml in the vendor directory with the right version.
Run rake build to build the trace-agent binary from current source
Or run rake install to install trace-agent to your $GOPATH

Testing

Lint with rake lint
Run the full CI suite locally with rake ci
Alternatively test individual packages like so go test ./agent
