List host's modified advanced settings via ESXCLI

Just wanted to share a great tip by Ather Beg on how to display all of ESXi host’s advanced settings which are different than the default values via ESXCLI:

esxcli system settings advanced list -d

This will return a list of advanced settings similar to:

...

   Path: /Net/TcpipHeapSize
   Type: integer
   Int Value: 32
   Default Int Value: 0
   Min Value: 0
   Max Value: 32
   String Value: 
   Default String Value: 
   Valid Characters: 
   Description: Initial size of the tcpip module heap in megabytes. (REQUIRES REBOOT!)

   Path: /NFS/MaxVolumes
   Type: integer
   Int Value: 256
   Default Int Value: 8
   Min Value: 8
   Max Value: 256
   String Value: 
   Default String Value: 
   Valid Characters: 
   Description: Maximum number of mounted NFS volumes. TCP/IP heap must be increased accordingly (Requires reboot)

...

where Int Value / String Value (depending whether the parameter stores its value as integer or string) shows the current value for the parameter, while Default Int Value / Default String Value show its default value.
