I have a custom snmp sensor for bandwidth monitoring of a radio link. This is a delta sensor setup as SNMP Custom sensor. It has 60s interval. Unfortunately in the Live data readouts are not in the 60s intervals but in some random 29-35s range. Why? I think that causes results to oscilate as it is a synchronus link at 160 Mbps.

I'm positive it is set to 60. The same ip has 4 more snmp sensors. More of them are broken in a same way 3 at 10 seconds interval (the update 5 to 6 seconds each) 1 at 60 s (updates at 25-30s)
I'm using latest relaese 8.1.2.1809 is that a bug?

Hello,
which exact version of PRTG are you running? With PRTG 8, the Probe Scheduler tries to "shift" scannings of all sensors of one device a little bit around, in order to achieve less load on the target itself. So that the sensors don't scan all at the same time. 29-35s is quite a difference, please check if the sensor is really set to 60s, with a 30s interval these differences might happen.
Best Regards.
