Performance
The Concentrator Performance window, Figure 6-5 , provides graphical and numeric
performance statistics for the selected SMT entity, including transmit frames, receive
frames, frame errors, lost frames, and ring ops.
Figure 6-5. The Concentrator 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 HSIM-F6 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 the concentrator performance for three different intervals:
• Absolute — Counts recorded since the SmartSwitch module was last started.
• Cumulative — Counts recorded since the Concentrator Performance window was
opened.
• Delta — Counts recorded during a single polling interval (refer to the Element
Manager User’s Guide for information on setting the polling interval).
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.
