Need script for proactive expiration of certificate for multiple Vcenters

[itvccops]

Need script for proactive expiration of certificate for multiple Vcenters.  We have 200  vcenters in our  environment . We need a script that  must  check the pro active status of the certificate expiration

[LucD]

With PowerCLI 13.1 you can use the Get-VIMachineCertificate cmdlet.

Connect to the vCenter for which you want to check the expiration date, then do

Get-VIMachineCertificate -VCenterOnly | Select Entity,NotValidAfter

[itvccops]

We have  200  vcenters  in our  environment . we  need  to a run only one script that should tell  the expiration of all VCs

[LucD]

Then you use a loop through all vCenters.
How would you provide the credentials to connect to each of these vCenters?

[itvccops]

Script  should  automatically  needs  to  connect  all  the Vcenters

[LucD]

That can be done with pass-through authentication (SSO based) or with the use of a CLIXML file (Export-CliXMl)?

[itvccops]

we  need  more  information here to configure  in our  environment 

[LucD]

And I need more information to be able to help you.

What does not work?
Any error messages?
