I am using the IMAP Round Trip sensor to monitor our outbound email sending. I have 2 sensors set up, one using GMail and one using AOL. Currently if either one is in error I get notified even if the other is working. AOL is flaky at times and is usually the one erroring out, but GMail is not 100% accurate either, hence using both sensors to monitor outbound.

I would like to set up a Sensor Factory sensor that monitors both IMAP sensors and only alerts me if both of them are in error. I have tried adding the downtime channels of each and checking if it's over 0 but I never get any data on my sensor.

Is there any way to have an alert trigger only if two sensors are in error?

hallo,

please take a look at the

Define Sensor Status—status() Function

section of

https://www.paessler.com/manuals/prtg9/sensor_factory_sensor.htm

status(2031) AND status(2044)

This will change the factory sensor to a Down status if both sensors, with IDs 2031 and 2044 , are Down . Otherwise the factory sensor will show an OK status.

Thank you. That looks to be a new feature as of PRTG 9. I just updated yesterday and it's there now.

Works perfectly for my situation.

Thank you.

I have a Sensor Factory of 8 Sensors. I want the Factory goes on warn if 2 sensors go down. And i want the Factory goes on error if 3 or more goes down. Any ideas?

Hi Capo,

This will work best with the new Busniess Process Sensor. You can add all eight sensors and define the percentage of failing sensors to either set the sensor into a warning, or into an error status.

This is also described in this article.

Best regards, Felix
