Part of the problem is that the measure of job queue length we really care about is "what was the last job executed?", not "how many jobs are in the queue?". If we added a job_timestamp column and put an index on it, we could replace (or supplement) the cruddy poor-quality estimate we have now with a probably more useful and certainly more accurate one.
Agree. Adding job queue lag to Special:Statistics would benefit both users and sysadmins.
I've been toying with some additions to the job queue so that we have some semblance about what is going on. Time stamp, actual stats of progress and if we want to get extra fancy, better view of what the job workers are doing.
Just simple things to help humans analyze what is going. And if were lucky .. maybe tell us why.
Now that I'm back, I'm hoping to have something ready for Brion and everyone to look at soon.
