This add-on provides two modular inputs to allow Splunk to ingest metrics from Prometheus (prometheus.io).
The first is via polling a Prometheus exporter, or the federation endpoint on a Prometheus server from Splunk. The second opens up a TCP port which can act as a remote write target for one or more Prometheus servers.
