Performance

The Performance window, Figure 4-5, provides graphical and numeric performance statistics for the selected SMT entity, including:

•Transmit Frames

•Receive Frames

•Frame Errors

•Lost Frames

•Ring Ops

Figure 4-5. Performance Window

Statistics are displayed in three ways:

•By count (i.e., the number detected of each for the selected interval).

•By rate (i.e., the number of each per second, as averaged over the selected interval).

•Graphically, as a percentage of each with respect to total network load processed by the selected interface during the last interval (e.g., a transmit frames rate of 75% during a delta interval indicates that of all frames processed by the selected interface, 75% were transmitted by that interface).

You can view performance for three different intervals:

•Absolute — Counts recorded since the selected module was last started.

•Cumulative — Counts recorded since the Performance window was opened.

•Delta — Counts recorded during a single polling interval that is set for SPECTRUM Element Manager (refer to the Installing and Using... guide for information on setting polling intervals).

To change the interval, click to select the desired radio button in the Count

Display panel in the top right hand corner of the window.
