    • Dragging the mouse over the Traces scatterchart plot can sometimes hang Kiali due to concurrent requests to the backend. The fix prevents the concurrent requests.

      This is a backport of an important fix identified upstream.   In most cases it is not going to be noticed but depending on environmental factors the Traces scatterplot chart can generate too many concurrent requests to the backend.

            pbajjuri0204 That looks perfect to me.  Good response time and as you can see in the Waterfall view, the requests are serialized, not concurrent. Good testing.

            Hi jshaughn@redhat.com :

            Deployed the SM 2.3.1 and Kiali 1.54.4

            Navigated to Kiali UI --> Workload --> Trace

            Please, can you check this Validation?

            If, it is ok - will close this Jira

            To test this simply visit the Traces tab for a workload and, assuming there are a variety of trace points, just drag  the mouse across and ensure that the proper heatmap tooltips appear, and with reasonable response.  If desired, check the Network tab in the browser debugger and note that the waterfull shows mostly sequential, not concurrent backend requests for 'metrics'.
