  +Every 5 seconds by default, Crunchy Prometheus will scrape the Crunchy Collect container
   for metrics.  These metrics will then be visualized by Crunchy Grafana.
   
   By default, Crunchy Prometheus detects which environment its running on (Docker, Kube or OCP)
   and applies a default configuration.  If this container is running on Kube or OCP,
   it will use the Kubernetes API to discover pods with the label *"crunchy-collect": "true"*.
