Roadmap
The following is only a selection of some of the major features we plan to implement in the near future. To get a more complete overview of planned features and current work, see the issue trackers for the various repositories, for example, the Prometheus server.
Server-side metric metadata support
At this time, metric types and other metadata are only used in the client libraries and in the exposition format, but not persisted or utilized in the Prometheus server. We plan on making use of this metadata in the future. The first step is to aggregate this data in-memory in Prometheus and provide it via an experimental API endpoint.
Adopt OpenMetrics
The OpenMetrics working group is developing a new standard for metric exposition. We plan to support this format in our client libraries and Prometheus itself.
TLS and authentication in HTTP serving endpoints
TLS and authentication are currently being rolled out to the Prometheus, Alertmanager, and the official exporters. Adding this support will make it easier for people to deploy Prometheus components securely without requiring a reverse proxy to add those features externally.
