In Salesforce, is there a way to send notification when too many records are created on an object in a day?
There is no other criteria than the fact that the records are created. So, we are not checking for values in specific fields.
I have tried creating reports/dashboard. But have not found a way to create the alert based on the number of records reported.
Create a report on records created today / yesterday. After saving you'll have an option to subscribe to it / schedule it. On that screen you can add extra send criteria such as only if row count > X.
There used to be something about sending Chatter posts when gauge charts met criteria (think "sales team closed 2M in deals, woohoo!" but I can't find any documentation, you might have to experiment.
