I need to know what a group's average uptime was over the past month or year.
It should be a simple calculation but I can't seem to find out where it is or how to get PRTG to report it. I need to tally up a group's Uptime sensors and divide it by a particular time frame to come up with a percentage, such as "99.716% uptime for all sensors in the Texas Group over the past 45 days".
Short of adding up all the numbers myself in some giant excel spreadsheet, how can I get PRTG to report this number to me automatically?
I read from a post on this KB last year that another user was having a similiar problem, and the support staff said that PRTG isn't able to do this simple calculation. That must be a bug or a mistake?
Also: I hate the captcha system on this KB. I've already passed the registration, why the additional verification?
