Hey Ben -
Used in a vacuum, this information might only be semi-useful - it's showing you how to watch & log resource utilization on a per-process basis. So what, right?
Well, if you have a history of memory utilization, you could mash it up against report requests and cross-reference by time. You'd be able to spot interesting patterns like the RAM being used by a vizQL process jumps way up when a user runs a specific report...and when that same report gets run by a couple different users during a small window of time, we see memory usage really spike, and then "out of memory" errors start hitting the Windows Log itself.
This type of question comes up quite a bit.The Tableau Server environment is unique to many of us and server performance tuning/monitoring is an ongoing topic of conversation. I often find myself trying to snake my way through the Forums, Whitepapers, Knowledgebase, etc to come up with some idea on how to resolve server performance issues.
Although there are third-party tools and some built-in Maintenance pages for Admins to help us monitor/troubleshoot, I think there is a market for a comprehensive, in-depth, nuts-and-bolts, technical course on server. I understand one is in the works and, personally, it can't come soon enough. We are struggling with monitoring and tuning our servers.
Well, speak o' the devil..... guess I should have checked first :-) http://tableausoftware.cvent.com/events/tableau-server-5-day-class-seattle-9-17-2012/event-summary-0f6cf5b3a09445a1be340370493f8173.aspx
Yeah, really excited about this class - Tableau actually put together a team for a week just to "brain dump" everything they thought should be in a course. There is a lot of collective wisdom summarized in this sucker!
Can't wait for this!
