Two years ago someone told me "I wish I could understand what Tokio is actually doing."
This really stuck with me and earlier this year I had both an idea and the time to try to make it happen. I think with dial9 that is finally possible. dial9 is a system to pull in a huge amount of events, very efficiently and analyze them later. Tokio is just one source of those events, but its a very important one.
Once we had Tokio, I realized we could also pull in lots of other sources as well; Linux kernel events, application events, tracing etc. etc.
Folks have already had good luck using dial9 to find tricky issues in prod.
