Hi Himanshu,
Welcome to Microsoft Q&A, Microsoft provides official docs that walk through both monitoring and debugging in Azure Data Factory. For monitoring, use the built-in monitoring pane in the ADF UI to track pipeline runs, trigger status, and activity-level metrics. For debugging, you can iteratively test pipelines using the "Debug" button in the authoring canvas, which lets you run pipelines without publishing. Also useful: integration runtime diagnostics, activity run error details, and retry policies.
Cheers,
Luis
