Hi Sridevi,
As mentioned in the documentation, whenever a flow is triggered, whether by an automatic trigger or by manually starting it, this is considered a run.
Say you have a flow that is triggered by Recurrence and the Frequency is 1 minute, then every minute the flow will be triggered and every trigger will be considered as a run, though your after actions are all failed.
So whenever the flow is triggered, it will be considered as a run.
You may also take this part for a reference, “Why did I run out of runs when my flow only ran a few times?”, it says that “Certain flows may run more frequently than you expect. For example, you might create a flow that sends you a push notification whenever your manager sends you an email. That flow must run every time you get an email (from anyone) because the flow must check whether the email came from your manager. This action counts as a run”.
Best regards,
