I like that the flow logs can be monitored from anywhere in the world, but it would be nice to have better control over the amount of data being stored vs sent. We use this for our streaming application so we are able to monitor the traffic between our client and server. It also helps us identify potential hiccups with the traffic which saves us time. I like that it can be set up to monitor many different streams, including from multiple applications running in various environments (e.g., Production & DEV). It's easy for me as an admin to change what is being monitored at any given time by simply editing one line of configuration text. Nothing so far - just working great! We have been able to use this product with our production application without having to create custom logs or write code ourselves anymore.
