  • Probe events and control objects views: Scales for duration and throughput columns are now configurable in the view settings dialog.
  • Probe events, control objects, current monitors and monitor history views: Multi-column filters with range editors for numeric values
  • Probe events view: Histograms for event durations and recorded throughputs are shown at the bottom. Events can be filtered by selecting an interval in the histograms.
  • Probe telemetries view: After selecting a time interval with the mouse, the events view will be shown with a corresponding time filter. This also works for probe telemetries that have been added to the VM telemetries.
  • Probe call tree and hot spots view: Added a "Show events" action that will set a corresponding call stack or hot spots filter and show the probe events view
  • The "Show events" action and the "Show in heap walker" actions in the control objects views of probes now support multiple selection of control objects
