To prevent this from happening we’ve implemented Error Throttling. From our docs:
With error events, it is common to have a flurry of repeated events with the same description. In some cases it may be helpful to log all of them, but most times you don’t want them eating through your daily event limit. By enabling Error Throttling, we’ll track duplicates of events tagged with “error” for a sliding 15-second window. Duplicate events won’t be logged. We’ll just record the number of duplicates on the original event.
You can turn this on in the advanced setting section. Please try it out and let us know how it works for you. It’s possible we will expand this feature to work with different kinds of events, but this seems to solve most of the issues our customers have requested.
