Answer 1

Hi Ritehere,
I know this is simple but am beginner in Powershell Script so I was looking for logic to go through however the output you provided is not what i am looking for and your script is too complicated, as under timestamp i wanted display value and correspoding
to display value the OID name and then name value correspoding to that OID. May be u got it wrong.
Thanks anyways.
