Monitoring of Zenoss (performance/health/status)

I want to proactive monitor performance, health and status of Zenoss. I identified 218 Zenoss specific metrics at the moment (related to official Zenoss Core 4.2.5):

• Zenoss Performance - 90 metrics
  standard metric logged by Zenoss (/opt/zenoss/perf/Daemons/*rrd)
• Zenoss logs - 44 metrics
  standard (error/warn/http 50x/...) log monitoring with counting of new log lines per minute
  
• Zenoss Processes - 54 metrics
  number of running processes for zen daemons, CPU and memory utilization per process
• Zenoss RabbitMQ - 21 metrics
  size and message rates of Zenoss queues, CPU and memory utilization
• Zenoss Ports - 9 metrics
  testingt of some known TCP/UDP Zenoss ports

Of course I monitor standard OS Linux and MySQL DB metrics and web check for Zenoss Web GUI. List of my metrics is available on https://github.com/jangaraj/Zabbix-Template-App-Zenoss

1. What do you (recommend to) monitor in Zenoss instance
2. Do you use some high level test scripts
3. Can you share some your good points please
4. Where is some documentation about Zenoss Performance Template metrics
5. Do you have some stress/performance test scripts for Zenoss

Devops Monitoring Expert advice: Dockerize/automate/monitor all the things.
