Watching the Watcher: Advanced Integrated Monitoring with Prometheus Federation

The name Prometheus is no longer synonymous with "The Messenger of the Gods". It has far greater responsibility in today's cloud native application environments.

This session will cover configuring Prometheus in a production environment with a focus on federating Prometheus deployments together.

Federation is the term that describes using one instance of Prometheus to scrape metrics from another instance, and it's not often talked about. Teams deploying Prometheus may want to use federation for any number of reasons:
- Their existing Prometheus installation is projected to outgrow its current hardware
- To manage performance as the number of samples collected by Prometheus grows
- Integrate a Prometheus deployment from a different application

Each of these topics will be explained and an example of federation will be demonstrated using Linkerd which includes its own Prometheus.
