Yes, I was going to do that after I add some links in it. > When it says "Events" on that page does it include all events (including view > events) or only some events (like only edit events)? Only events stored by the activity stream. It doesn't include view events, it used to store only create/update/delete document events, but since 2.6 it also stores comment/attachment/annotation events. > However the issue is that we can't really translate the number of events with > the wiki farm's load, can we? No, that's not a very good indicator of the wiki maintainance. Some wikis could have plenty of view, although little edits. But it's a starting point in determining which wikis should be parked. Still, a wiki with no activity wouldn't be such a problem for the farm, since it doesn't consume a lot of resources. On the contrary, most active wikis should be moved to their own server. > Thanks > -Vincent > >>> Note that we plan to add a new machine for myxwiki soon, and configure >>> a load balancer in front of the 2 machines. >> >> Maybe the current machine could be reinstalled from scratch, since the >> mysql socket problem isn't solved yet. >> >> Reminder, the problem I'm talking about is that in most myxwiki restart >> logs, mysql processlist shows open connection that are in a NULL state >> (they're done executing the query and sending the response), while java >> lists several threads blocked on reading data from mysql, data that >> won't ever come since mysql considers it did all its work. >> >>> Jerome. >>> >>> On Fri, Jan 28, 2011 at 10:36 AM, Vincent Massol<[email protected]> >>> wrote: >>>> Hi devs, >>>> >>>> We're accepting new wikis on myxwiki.org as requests come in but we >>>> already have 110 wikis created on it. >>>> >>>> When do we know we shouldn't accept new wiki creation on that JVM because >>>> it's degrading performances too much? >>>> Do we have tool to monitor wiki activity and publish on a page which wikis >>>> are using the most resources? >>>> Do we have tools to display response time stats and see how they evolve >>>> over time? >>>> >>>> Thanks >>>> -Vincent -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
