@ecrupper I'm sure this is answered in the underlying server source code, but I'm curious: will this page only show workers that have checked in within the last x interval? I'm specifically asking since our workers table is quite "dirty" with old workers due to the amount of auto-scaling we do on a daily basis.

Yeah something like that is definitely my vision for this (slated for v0.23). Maybe leveraging the active column? Check in logic works too.

A few things I want to see most from this page: some sort of filtering on check-in logic / active status, ability to update routes, ability to click on running builds and be directed to that build's page
