I have an environment where I want to create dynamic queries based on the Polling Engine used for the node. . I would want to separate out nodes based on an IP address as well as the polling engine because there could be multiple devices with the same IP address. For example, I have the Main Polling Engine and two Additional Polling Engines. There are 3 different 192.168.1.100 IPs across the three polling engines. Instead of having custom properties for each of the devices, I would like to use an already defined parameter like which polling engine discovered the device or polls the device.
