I want to graph the number of threads in a process, have found the ThreadID coloumn and set the Unique Count aggregation which is what I want to see over time. I have this field alone to the right of the blue bar, but no graph is shown (yes I have selected the legend colour).
How is this possible ?
Right click on the Thread ID column name, and choose Open View Editor. In the opened window, scroll the list down until you see the Thread ID entry. Under the Aggregation column, select Count.
Now it should display a graph of the amount of threads.
Notice that you should correctly set the first column in the left-most part of the table, to either Process, or Thread Start Module, according to your need.
