Configuring Evt Logging - Motorola BSR 2000 Configuration And Management Manual

Release 1.0 Configuring the System

Configuring EVT Logging

The EVT system is an enhancement to the BSR logging mechanism that provides the
ability to monitor internal system events. This allows for additional granularity in
monitoring system activity. As EVT monitored events occur, they can be logged in a
similar manner as the existing BSR logging mechanism although the configuration
procedure for EVT logging is different. The EVT system monitors events by counting
the number of times that an event occurred. The EVT system can also optionally
display console messages, SYSLOG messages, SNMP traps or log entries in
non-volatile memory to provide more detailed information. Event counters are always
enabled, regardless of whether the generated event displays an optional message. The
counters can be queried to determine if a particular event has occurred. The EVT
reporting mechanism provides information as to when the event occurred. EVT
reporting has default options based on the severity level of the event which can be
customized.
EVT counts are organized into named groups which can be displayed, reset, and
logged on a per-group basis. Each event within an EVT group is numbered from 1 to
255 and additionally identified with the group's EVT base number. EVTs can always
be observed by displaying the EVT count with the show evt command while system
log messages are only observed if the log message's severity level is configured for
logging in advance. Logging for each EVT can be controlled on an individual basis to
any combination of four logging destinations (logging buffer, console, SNMP traps,
and SYSLOG).
Display of an EVT group provides a "snapshot" of the group's function (e.g. the
number of packets forwarded or the number of errors observed). Multiple EVT groups
can also provide a longer-term "snapshot" of the activities and overall system health
of the BSR.
Caution: Enabling EVT message displays can cause system performance
and timing problems due to the volume of messages generated. To avoid
these potential "EVT floods", contact customer support before changing any
EVT default configuration.
Note: Contact customer support if EVT messages with a severity level of
"alert", "warning", or "error" are being generated.
