Custom SD
Custom SD is available via the file_sd adapter, which can be used to access SD mechanisms that are not
included in official Prometheus releases. The sd adapter outputs a file that can be passed via your prometheus.yml
as a file_sd file. This will allow you to pass your targets to Prometheus for scraping without having
to use a static config.
Example
This directory (documentation/examples/custom-sd) contains an example custom service discovery implementation
as well as a file_sd adapter usage. adapter-usage contains the Discoverer implementation for a basic Consul
service discovery mechanism. It simply queries Consul for all it's known services (except Consul itself),
and sends them along with all the other service data as labels as a TargetGroup.
The adapter directory contains the adapter code you will want to important and pass your Discoverer
implementation to.
Usage
To use file_sd adapter you must implement a Discoverer. In adapter-usage/main.go replace the example
SD config and create an instance of your SD implementation to pass to the Adapter's NewAdapter. See the
Note: comments for the structs and Run function.
