Powercli to get "show system storage " output of all NSX Edges

Hi team ,

        i am looking for a script where i can run  "show system storage " command on NSX edges and get the output .  Please let me know if it is possible or not . I know Edges have Vmware tools installed so we can invoke the script . The reason i asked this question is we are using NSX 6.3.2 and Edges disk get full specially /var/log partition . i want to run Script  weekly  and get the output .

I am aware that we can get disk capacity and free disk space of a Virtual machine , but it does not help where a Linux Virtual machine have multiple partions on a particalur disk .

Is there any way i can get the partitions inside the Virtual Machine and get their usage .

Thanks for help. this is what i am looking for

Did you already try running that command through Invoke-VMScript?

Basically it's nothing more than

$vmName = 'VM-Name'

$code = @'

show system storage

'@


$cred = Get-Credential -Message "Provide credentials for VM $($vmName)"


Invoke-VMScript -VM $vmName -ScriptText $code -ScriptType Bash -GuestCredential $cred

Are the VMware Tools running in the VM?

Could it be that access to the VM's ESXi node is blocked?
This requires port 902

Hi Lucd,

    Yes it may be  but i dont have access to Firewall's , so cant verify .

. Coming back to my original request , can you help  me with any other way that i can get disk partitions of NSX edges and their % use.

NSX-edge-74-0> show system  storage

Filesystem      Size  Used Avail Use% Mounted on

/dev/root       444M  355M   65M  85% /

tmpfs           498M   80K  498M   1% /run

/dev/sda2        43M  924K   40M   3% /var/db

/dev/sda3        27M  413K   25M   2% /var/dumpfiles

/dev/sda4        32M  4.4M   26M  15% /var/log

For example : above shows  /dev/sd4 is 15% used .

Does this give you the required info?

It doesn't show the Use% directly, but the numbers to calculate are there
