title: Prometheus in Kubernetes cluster using Istio
body: <p>We have an existing Kubernetes cluster running that is using Istio. I was planning on adding a new Prometheus pod and can find plenty of blogs on how to do it. However, I noticed Istio already has a Prometheus service running in the <strong>Istio-System</strong> namespace.</p>
  
  <p>My main goal is to get Grafana running with a few basic monitoring dashboards. Should I go ahead and use Istio's Prometheus service? What are the advantages/disadvantages of using Istio's Prometheus service over running my own?</p>
