Alert for datasource instance datapoints based on Instance Description. Currently we cannot create an alert for datasource instance based on Instance description.

Thanks for replying to this topic. I just like to mention that the instance description is custom updated post its discovery and i need create an alert based on that description. Now i use a different data source then the discovered instances will default description which is null in my case. Because of this i believe i will not be able to use this solution. Please clarify. I think using groovy to create a complex datapoint should work.. but i need to learn how to do that.
