I was just looking around in graphite for job queue length and push/pop metrics in order to create a grafana dashboard & alerts for them (especially for Restbase update jobs, but can create a global one too):

• length, push, pop rates (global, by job type + wiki)
• push to pop latency (global, by job type + wiki)

a) is this information already available (which keys?), and if not,
b) would it be hard to add this?
