Articles
Edgar: Solving Mysteries Faster with Observability
We built Edgar to ease this burden, by empowering our users to troubleshoot distributed systems efficiently with the help of a summarized presentation of request tracing, logs, analysis, and metadata.
Kevin Lew, Maulik Pandey, Narayanan Arunachalam, Dustin Haffner, Andrei Ushakov, Seth Katz, Greg Burrell, Ram Vaithilingam, Mike Smith and Elizabeth Carretto — Netflix
- An article on 09/03/2020 that introduces “Edgar”, a self-service tool for troubleshooting Netflix’s distributed systems. At that time, the following answer was given to a “request for open source it”.
- Unfortunately, we don’t have any short-term plans to open source Edgar, but it’s on our radar as something to consider. A lot of Edgar is very Netflix-specific, and we’d have some work to do to make it abstract enough and consumable enough for open source. But maybe someday!
