+ <summary>
+ Total duration of renderer tasks split per task queue type. Used to monitor
+ usage of each type of task queues. Reported each time when task is completed
+ and current accumulated duration is longer than 1ms.
+
+ This metric is susceptible to problematic outliers and should be analyzed
+ with custom scripts accounting for that instead for a dashboard.
