VMware posters were always very popular. Those free posters could usually found at HOL during VMworlds or you could download your copy as a PDF and print. If you?re learning PowerShell then you will love this new PowerCLI 5.8 R1 poster which has new and updated commands.

Another example using PowerCLI is using ESXTOP:
# View the fields available for vCPU counter:
(Get-EsxTop ?Counter ?CounterName VCPU).Fields
# View the entries of a specific topology:
(Get-EsxTop ?TopologyInfo ?Topology SchedGroup).Entries | FT
# Retrieve the counter values for ?VCPU? and ?SchedGroup" counters:
Get-EsxTop ?CounterName VCPU | FT * -AutoSize
Get-EsxTop ?CounterName SchedGroup | FT * -AutoSize
I usually struggle to remember those commands and the exact syntax. This visual help is certainly very useful for every VMware admin out there. Get your copy!
