Node-RED connector Warnings and Notifications.



Hello, I am developing an application on Node-RED and I would like to use PRTG Network Monitor to handle the notification to the user. But I don't know how to tell PRTG to send the notification or change the sensor state to warning. In the Custom sensor web page explains that there are TAGs like Warning and NotifyChanged, but I don't know how to configure using the PRTG Node-RED Connector. Thanks!

Hello Ricardo, Yes, I successfully inject data from node-Red into a "IoT Push Data (Advanced) (HTTP)" sensor. It was a very happy moment. The key is that Node-RED is the main application for my project, only in Node-RED are stored the High and High-High Levels of the sensor. And it's not a nice practice to have to repeat this configuration in another system, like PRTG. So, the custom sensor JSON has the Tags to tell PRTG that:

  • the sensor is "<Warning>" (aka High Level)
  • to send a notification to the user with the tag "<NotifyChanged>"
  • the sensor has a problem "<Error>"

src: PRTG Manual: Custom Sensors

I have tested this TAGs from a browser (using xml, not json) and it worked as I needed, but this TAGs seems not implemented in the PRTG Node-RED connector. am I right? Would be possible to ask for this functionalitys to be added to the connector?

Warning and Notify TAGs:<prtg><result><channel>temperatura</channel><value>10</value><warning>1</warning><notifychanged></notifychanged></result><text>this%20is%20a%20warning%20message</text></prtg>

Error TAG<prtg><result><channel>temperatura</channel><value>20</value></result><error>1</error><text>this%20is%20a%20error%20message</text></prtg>

Reading now the Custom Sensor Manual, the TAGs "<LimitMaxWarning>" and "<LimitMaxError>" to tell to PRTG the High and High-High Level, would be handy too.

Thank You!!
