Metric Registrar CLI

Plugin for the CF CLI that allows users to register metric sources for collection.

Installing Plugin

cf install-plugin -r CF-Community "metric-registrar"

   --internal-port      Port for secure metrics endpoint scraping

Structured Log Format

Registering a structured log format will allow for structured logs of that format to be parsed into metrics and events and emitted to Loggregator.
