Kubernetes collection - Separated Prometheus installation pros / cons

Hi,

I've followed this tutorial for setting up the  Kubernetes collector with helm (helm 2 in my case) in a sandbox environment and everything went OK, I was able to see the cluster and the dashboards in the SumoLogic UI. I had no previous Prometheus operator installed so I followed the main procedure (the one that assumes that there is no Prometheus in the cluster).

Now I have to deploy this solution to multiple environments (starting with Test) which already have prometheus installed and I'm not sure of the pros and cons of having a separated prometheus for Sumo or integrate it with the existing prometheus installation.

Any advice of the pros and cons of running multiple prometheus will be greatly appreciated.

Thank you!
