From https://github.com/blog/542-introducing-resque

We are constantly overloaded and rely very, very heavily on our queue. If it’s
backed up, we need to know why. We need to know if we can fix it. We need
workers to not get stuck and we need to know when they are stuck.

We need to see what the queue is doing. We need to see what jobs have failed.
We need stats: how long are workers living, how many jobs are they processing,
how many jobs have been processed total, how many errors have there been, are
errors being repeated, did a deploy introduce a new one?
