We have tested some IP SLA Sensors. But given following scenario:
We setup a sensor that sends a UDP echo 10x/second to a destination. PRTG gets his values after 10sec (earliest you can configure PRTG to do). So for each read, there should be 100 values that need to be examined. So if 2 of these 100 packets failed (time out) and the 98 others were successful, what is PRTG displaying for this one read? The sensor is not down, because some packets did arrive, the sensor shouldnt be up either, because some packets did not. What is the behaviour of PRTG in such a case?
I have read the manual at: https://www.paessler.com/manuals/prtg/cisco_ip_sla_sensor and it didnt answer my question. It just says: "Packet Loss values are summarized"
