datadog-service-helper

The purpose of this tool is to easy datadog service monitoring in a docker environment where services change port and host all the time.

The daemon will run on each server you have (e.g. through Nomad) and tail the local consul agents service catalog, and write DataDog agent configuration files, based on the catalog state.

Usage

If a consul service has a tag called dd-<service_type> the tool will ensure it will be monitored by the local DataDog agent.

Nomad example:

service {
    name = "datadog-service-helper"
    port = "http"
    tags = ["dd-go-expvar"]
}
