• Job queue - Note, the api can still return an estimate (emphasis on estimate, its known to be wildly inaccurate in some cases). Currently it shows enwikipedia has about 30000 jobs. Bawolff (talk) 15:36, 31 January 2013 (UTC)

  Sure, but it's not possible to see trends (unless one is very careful and notes down the numbers, of course). Ganglia was made public five minutes ago, here's the graph again.[1] :-) --Nemo 20:53, 31 January 2013 (UTC)

  Thanks Nemo. Welcome back, Ganglia!

  1. The Ganglia data would be a little more useful if it showed the maximum and minimum values for each aggregated period, instead of only the value for an arbitrary point in time in each hour/day/week/month.
  2. It would be more helpful for a log to show also the timestamp of the oldest job as well as the number of entries over time. Better still, a breakdown for each type of job – something like:

     SELECT job_cmd, COUNT(*), MIN(job_timestamp) FROM job GROUP BY job_cmd;
     

     I don't think the job tables are replicated to the toolserver, so Ganglia would probably be the easiest way to make this information available.

  got to say its really nice to see ganglia back.Bawolff (talk) 23:38, 31 January 2013 (UTC)

  Richardguk, I agree with you but we don't even have a ganglia graph for all wikis (gerrit:37441)... Maybe you could propose some patch to ganglia, or to gdash [2] (where we have [3])? --Nemo 10:07, 1 February 2013 (UTC)
