ESXCLI returning {VMware.VimAutomation.ViCore.Impl.V1.EsxCli.EsxCliObjectImpl}

Hi Im trying to retrieve cache stats though powerCLI using Get-EsxCli, but its not returning all values.

Is this a known problem ?

PowerCLI version VMware-PowerCLI-6.5.0-4624819. ( 6.5.0.234 )
OS Windows 10
vCenter 6.5.0 Build 4602587

Do you get the missing data when you do this with the esxcli command in a SSH session to the ESXi node?

[SonnyToft]

Yes, SSH esxcli works perfect.

Did you expand the nested objects?

Try something like this (you might want to lower/increase the Depth value)

$esxcli.storage.vflash.cache.stats.get.Invoke(@{cachename = 'vfc-2609293434-ly-cg-20_2'; modulename = 'vfc'}) |

Format-Custom -Depth 3

That did the job. Thanks for the help.
