PRTG sensor alarm based on value in some time range




My sensor count switch dropped packets. I would like to set alarm basen on dropped packets count in some time period. For example. If switch will drop 100 packets during one hour it is not error, but if 100 packets will drop in one minute it is error.

Is any way to realize this alarm?

Dear Sebastian,

depending on the sensor channel unit type, you can add a speed trigger in order to alert when a given bandwidth is reached. Please open this manual page and scroll to Add Speed Trigger.

Unfortunately I cannot add Speed Triger. Only State, Threshold and Change triggers are available.

It is Custom SNMP sensor.

Dear Sebastian,

in this case, you cannot alert on bandwidth. You could try to re-create the sensor and select the "Delta (Counter)" option. This yields a bandwidth unit.
