 If you want to monitor more than one ZVM/vCenter you can add additional zvmexporter containers. 
 
-For each site you want to monitor you need to copy the following yaml lines
+For each site you want to monitor you need to have an exporter configured like the lines below. By default the docker-compose.yaml has two exporters for a production and DR site, but you can add more sites to achieve a single pain of glass for monitoring all the ZVM's that are reachable from your docker host.

-Next, modify the prometheus configuration and add additional scrape jobs for each new exporter. You will have 4 scrape jobs for each exporter.
-Notice the job names and target ports have been updated to reflect the 2nd exporter.
