Pre-Roll Ad Metrics Monitoring

I need a straightforward, reliable way to keep tabs on how my pre-roll video ads perform across YouTube, Facebook, Instagram and any other site where they might show up. The only numbers that matter to me right now are:

• View count (how many times the ad actually starts)
• Timestamp (the date and time they have been view)
• Watch time (how long viewers stay with it)
• Full or partial view
• A clear note of which site served each impression

If you can build or configure a solution that pulls those data points automatically—whether through the native APIs, a lightweight scraper, or a custom analytics layer—let’s talk. I’m happy with a dashboard, a scheduled report, or raw exports as long as the data are accurate and refreshed frequently enough for real-time decision-making.

Please outline the approach, the tools you plan to use, and a quick sample of the output I can expect so I know the format before we begin.
