Verify that the Azure Event Grid subscription is still active and properly configured. Sometimes subscriptions can be inadvertently modified or disabled. Take a look at the logs of your Azure Storage Account to ensure that events are being generated as expected. If there are no events being logged, the issue might be with the Storage Account rather than the Data Factory. I found this old thread, hope it helps. https://stackoverflow.com/questions/76384111/the-data-factory-event-triggers-arent-always-running
Data Factory: Storage Events missing suddenlty

Hello, For months our Data Factory was running fine. Now (without any change/release/etc.) it is not handling any storage account events anymore. Disabling the trigger and re-enabling did not work. According to the 'Resource health' of Data Factory, everything is healthy? Do you have any experience with this issue? Any clous? Many thanks!!!! Lou
