Configuring the WSM using Device Manager

Statistics and history

BWM statistics are maintained so that WSM owners can bill for bandwidth usage. You can configure statistics for frequency and count. Statistics are kept in the individual Switch Processors (SP) and then collected every second by the Management Processor (MP). The MP then combines the statistics, as statistics for some classifications may be spread across multiple SPs. The MP maintains some global statistics, such as total octets and history.

History is maintained only for the contracts for which the history option is enabled on the Traffic Contracts tab. When the history buffer of 128K is ready to overflow, it can be e-mailed to a user for long-term storage. Device Manager can be configured to send the contents of the history buffer to the user.
