My PRTG server's internet connection tends to be unstable and when it goes offline for a few minutes this triggers plenty of sensor alerts. Is it possible to configure notification triggers as follows:
if Sensor1 (HTTP, google.com) has the Status OK and Sensor2 hast Status DOWN > send Alert Notification for Sensor2
...so Alert Notifications will not trigger if the PRTG-Server is offline.
Thanks in advance!

Hello,
Thank you for the KB-Post.
I'm afraid there isn't a single button to solve this. It's a bit more complicated.
Dependencies can help in such situations. It is not possible, to set two dependencies on an object. So a switch for example, has its own dependency from its own Ping Sensor, and then has to have a 2nd dependency coming from a router. This is not possible. In order to achieve this, another object as level between has to be introduced.
The important thing is to make the sensors and devices dependent on the "main Ping Sensor". You can also work with sub-groups/cascading groups here, to make entire groups depending on a Ping Sensor (of the Router). So here, create a group with all servers, etc. that are actually "behind" this router, and then make this sub-group dependent on the Ping-Sensor of the router. And then keep the device-dependencies on the "switch-device" and its own Ping-Sensor will be the master object for this device and then pause all sensors on the switch, if only the swtich is down.
It may also help, to look into the Notification Summarization Settings, which summarize several notifications, if they occur within a certain time limit.
