EARLY FIELD TRIAL Chapter 3 50 Sniffer Adaptive Application Analyzer traffic seen during the time selection when Top N is set to All. See Working with the Top N Feature on page 95 for details on how this counter works when Top N is enabled. NOTE: The Selected value does not appear when the Summary, Errors, or Destination tab is active in the Statistics panel. a a W b c b Figure 3-3. Graph Panel Updating Graph Panel Statistics The Console reads and reports the time values in the Graph Panel when a stream is opened and, by default, whenever the graph selection changes. You can change the default behavior using the Refresh statistics whenever graph selection changes option in Quick Select > Options > General; refer to Setting General Tab Options on page 243 for details. On actively capturing streams, the Console does not automatically update the Available End time – your most recent capture time. You can update the stream to the most current data by clicking either the Current Time or the Active Monitor button . See Monitoring for Updates – Active Monitor Mode on page 54 for more on updating stream data in the Graph window. NOTE: One-second selections – the smallest supported selection – results in identical Start and End times. For instance, a one-second time selection setup at Noon displays a Start and End time of 12:00:00.

EARLY FIELD TRIAL Using the Time Selector Working with the Quick Select Window The Time Selector (a) appears in the form of a shaded bar which travels parallel along the Graph panel’s horizontal scroll bar. Two gray handles appear on either side of the Time Selector, which you drag to set the Start and End times. Figure 3-4. Time Selector (Full View and Close-up) When you initially open a stream, the time selector appears over the last one minute of the stream data (though you’ll need to wait for the first 15 seconds of monitoring to pass before statistics/packets are available): Make adjustments by dragging one (or both) of the time selector handles to the desired location. Drag the entire Time Selector by grabbing the gray connecting bar. Watch the selection’s Start and End times change when you shift the selector’s position. When moving the time selector, the handles automatically snap to the closest 15 second time increment, unless you manually override this default. See Adjusting the Time Selection on page 52. NOTE: The snapping time increment changes depending on the Graph Panel zoom level. a User’s Guide 51
