There are some endpoints used in OpenShift/Kubernetes that stores
metrics
using the Prometheus protocol. These endpoint expose metrics in which
Prometheus (or something which understands the protocol) can then bring into
their system. We are looking at potentially being able to read from these
endpoint types, not being able to read from a Prometheus server itself.
Then it sounds more like we'd want to have some kind of plugin or component inside
Hawkular-Metrics itself so H-Metrics can just pull metrics in using the Prometheus
protocol (in addition to getting metrics pushed into it via its REST API). This could be
an optional component to Hawkular-Metrics for those that don't need or want it. But it
sounds like this is just another protocol to insert data into H-Metrics.
