The current thread state graph is great and does a good job of showing the overall state of the threads in an application. A handy enhancement would be if the same type of information were available as text in a sortable table. The table would have nine columns: 1. Threads - contains the name of the thread, just like in the current thread state graph. 2. Running - Amount of time during the thread's life that it has been in Running state. 3. Running % - Amount of time during the thread's life that it has been in Running state, shown as a percentage of the total time that the thread has been alive. Columns 4-9 would be the same as columns 2 and 3, only for Sleeping, Wait, and Monitor. This would allow the user to click a column header and sort the table of threads, making it easy to quickly spot the threads that for example have spent a large percentage of their time in Monitor state. For large applications with many threads, this would be much easier than paging through the current thread state graph looking for bars that are primarily red in color. As far as fitting this into the existing UI, seems like it should just be another tab. The two current tabs are "Threads(Timeline)" and "Threads(Details)." Perhaps this new tab could be labeled "Threads(Percentages)" or "Threads(Time)." The little controls that allow zoom-in, zoom-out, and "scale to fit" of the timeline should be disabled or hidden completely when this new tab has focus. The drop-down for controlling which threads to display would still work, however.
Implemented as a table with columns containing both absolute and relative times for each thread state - I'm not sure if extra columns for percentage values are really useful. Let's evaluate users feedback and eventually add the percentage bars later. Implemented for 6.5 M2. changeset: 87583:767a33c9a90b date: Fri Jul 04 17:58:45 2008 +0200 summary: Implemented #100662: Tabular version of Thread State information

>I'm not sure if extra columns for percentage values are really useful. The use case I was thinking of was an application with a large number of threads (thousands of threads). If I want to see the threads that spent a large percentage of their time in a particular state, then I need the ability to sort on percentage. So for example, if thread A spent 45 seconds of its 2 hour life in Monitor mode and thread B spent 10 seconds of its 11 second life in Monitor mode when I click the Monitor column, thread A will always be listed *before* thread B (when sorted in descending order). But thread B (and similar threads: short life, but much of it in Monitor mode) is what I might need to see - because it spent a large percentage of its time in Monitor mode. In other words, since threads can live for such widely varying amounts of time, the ability to sort just by percentage could be convenient. >Let's evaluate users feedback Agreed. :-) >and eventually add the percentage bars later. I'm not sure I understand this: "percentage bars." Did you mean "percentage column"?
