Application Insights: Allow for alerts based on filters
Currently alerts can only be applied per Metric (see screenshot).
It would be extremely helpful to trigger alerts based on filtered telemetry. E.g. Exception of type IOException, since often times third party libraries cause Exceptions that are just 'noise'.
So like with any logging: the challenge is finding the signal within the noise.
A very simple solution would be to add 'favourites' to the metrics drop down.
So you'd see in metrics drop down additional options like 'Favourite: IOExceptions' and 'Favourite: Slow Homepage load in Chrome'.
