Bare bones lab build

I'm coming back to Zenoss as admin and want to build a Community Edition from scratch on a minimally provisioned ESX 6.5 server with only 16 Gig of RAM total. The Zenoss Master ISO is installed with NOTHING else on the ESX and NOTHING added to the master. The Master ISO VM has 2 CPUs;  8 Gig RAM and 250 Gig Disk. 

I'm trying to understand at a basic level what is the minimal build I can create to better understand every nuance of the process. The instance is a lab instance that will only discovery a handful of desktops. 

Has anyone done this?  What would be the early steps to add to the Master? Obviously Docker, Control Center etc. 

Thanks,
-Rob

Robert,

With only 2x vCPUs, performance is going to be "iffy" during startup as dozens of services compete for processor time.  Once you're running, you may be able to free up some additional headroom by disabling unused collector services (i.e., if you're not sending traps and syslog messages, turn off zentrap and zensyslog).

If possible, I would recommend bumping up the hardware on the VM since you're currently pretty far from the minimums.  You might be able to "get away with it," but you may end up spending more of your time fighting the ship instead of captaining it.

Did you have any specific goals or things you were looking to learn?
