Hi Jim,
You can do this from Spectrum Control Panel. Refer the below screenshot.
And to use the command line utility, navigate to $SPECROOT/PView directory and you have different files.
Use the below Syntax to run the report from command line.
./pviewrep vnm [-c collectTime] [-e addrList]
Here, vnm is the Spectrum server you would like to run the report on.
collectTime is the duration in hours to collect the data (min. 6 hours)
addrList is the list of email addresses to send the report to. If you use more than one email, use comma to separate each email ID.
After mentioned period, the report is saved as vnm[_#].htm. The file number will be increased in order to prevent overwriting the old reports.
Below is an example.
Hope this helps.
Cheers..
