I hope later posts in this series explore Linux perf_events or flame graphs, which is the origin of the (unattributed) background image (http://www.brendangregg.com/FlameGraphs/cpuflamegraphs.html http://www.brendangregg.com/FlameGraphs/cpuflamegraphs.html). :)
- fsaintjacques 11y agoSince you are here, how do you handle CPU (or code) graphing on distributed systems? In his case, you do not control which nodes and/or when the query will be executed. Any tips?
- tobz 11y agoHeyo! Sorry about the attribution. I'm trying to find who controls the blog as we speak so I can have them add it. (I work at Localytics, but I'm not the author.) We've gingerly explored flame graphs to understand Vertica behavior under load, and we still have a lot that we want to try and use it for. I'm not sure if it will make an appearance in a further post, but we've definitely used your perf_event/ftrace-based tooling. :)
- ptothek2 11y ago@brendangregg It was my bad, and you're totally right. I should not have let that fall to the wayside here. We're adding it ASAP. I'm sorry about that.
