Description

We need some sort of metrics that we can alert on when the aggregation job creator encounters errors fetching tasks. We had a submarine error here, which resulted in it spawning no async tasks and doing no work.

Research direction

Start by locating the aggregation job creator and the path where fetching tasks produces "Couldn't update tasks" errors. Review existing metrics and determine how to expose these failures so an alert can detect when no asynchronous tasks are spawned; done means the error condition is measurable and alertable.
