Azure logic app costs for EVALUATION of ftp (when a file is added or modified)?

Question

I am using a logic app to monitor the FTP folder whenever a new file is created or modified.

I see the evaluation block as evaluated 319 times in 24 hours and fired 1 time in the last 24 hours

I wanted to know whether the azure logic app costs for the number of evaluated times? or only for fired time execution?

Answer 1

As far as I know, Evaluation shows all the trigger attempts that your logic app has made, including success, failure, and skip. Whether or not billing needs to be determined according to the operation result.

When a file is added or modified(properties only) trigger is a Polling trigger，even if the trigger is not triggered, the polling operation of the trigger will still be billed.

For more details, you can refer to Pricing model for Azure Logic Apps

Therefore, only the cost of the trigger in the polling operation (skip state) and the cost of trigger and all actions after the logic app instance runs successfully are charged.
