Docker Flow Monitor: Automatically Reconfigure Prometheus

Docker Flow Monitor

The goal of the Docker Flow Monitor project is to provide an easy way to reconfigure Prometheus every time a new service is deployed, or when a service is updated. It does not try to "reinvent the wheel", but to leverage the existing leaders and combine them through an easy to use integration. It uses Prometheus as a metrics storage and query engine and adds custom logic that allows on-demand reconfiguration.

Please visit the tutorial for a brief introduction or Configuring Docker Flow Monitor and Usage sections for more details.

Please join the #df-monitor Slack channel in DevOps20 if you have any questions, suggestions, or problems.
