+# Istio virtualservice for Collectd, CAdvisor, Node Exporter
+
+The following values has to be updated depending on the Cluster's installation in values.yaml
+
+1. allowedhosts - hostname or FQDN for collection service (used by Prometheus to discover scraping target)
+2. gateways - Name of the Istio gateway to which this virtualservice will be connected to
+3. destinationhost - collection service name
+4. port - port of the collection service
+
+# Installation
+1. helm install collectd-istio-connectivity -n edge1
+2. helm install cadvisor-istio-connectivity -n edge1
+3. helm install node-exporter-istio-connectivity -n edge1
+
+NOTE - The namespace (edge1) is used an example. This has to be changed to be namespace where collectd is deployed.

+2. gateways - Name of the Istio gateway to which this virtualservice will be connected to
+3. destinationhost - m3coordinator service name
+4. port - port of the m3coordinator service
+
+# Installation
+1. helm install m3db-istio-connectivity -n training
