Performance View gives information about the performance of the SpectroSERVER and can also gather information to have emailed out in a report after 24 hours.
The following link provides some basic info on Performance View. https://docops.ca.com/ca-spectrum/10-2-3/en/administrating/spectroserver-performance-administration/performance-optimization/getting-started-with-performance-view/
This should not degrade server performance. The reports are not setup to run regularly so you would need to start the "Data Collection" when you want to monitor it. Then once it is finished collecting the setting can have it email you the report. Below are the steps:
1) On the SpectroSERVER Spectrum Control Panel go to Control > SPECTRUM Performance
2) Go to the "Set user preferences" button on the top under Options/Help
3) Check off "Email Report When Complete" and enter the email you want it sent to then select OK
4) Go to the "Health Report" Tab and select "Start" under the "Data Collection" area.
When the collection period is done (24 hours) the report should be emailed to you.
