Hello,

uptime means the uptime of course. For requests it's slightly different, because PRTG only accounts downtime between at least two consecutive failed scans. So if only one request fails, it's accounted as failed/bad request but does not effect uptime. If a scan fails, the sensor goes down. To be exact, with most sensors after a failed scan PRTG performs an immediate re-scan and if these both fail, the sensor goes into down state. But that gives no exact measurement for downtime, PRTG can't know how long the target is already down. So it takes at least one more scan following the scanning interval for PRTG to have a proper valid statement for downtime.

best regards.
