Chapter 7 Performance Monitoring
Monitoring SONET Performance
Viewing Line Total Statistics
Total statistics are performance statistics collected since the previous midnight. So just before midnight
there are almost 24 hours of statistics available, at midnight the statistic counters are reset, and after
midnight the system starts accumulating new data. To view total statistics for a single line, enter the
lsslinetst command, specifying the slot and line number delimited by a period. The system displays the
total statistics for the specified line:
=======================================================================
Sonet Line Total Statistics (lsslinetst)
=======================================================================
Sonet Line Slot.Line : 9.1
Errored Seconds : 0
Severely Errored Seconds : 0
Coding Voilations : 0
UnAvailable Seconds : 8729
To view total statistics for all lines, enter the lsslinetsts command. The system displays total statistics
for all lines:
=======================================================================
Sonet Line Total Statistics for all Lines (lsslinetsts)
=======================================================================
Slot.Line Error Secs SeverSecs CodingVoilations UnAvailSecs
========= =========== ========= ============= ===========
9.1 0 0 0 87293
9.2 0 0 0 63892
Clearing Line Total Statistics
To clear statistics, enter the clrslinetst command, specifying the slot and line number, delimited by a
period, and the statistical counter to clear. Specify the counter as follows:
1—None
2—All
3—ES
4—SES
5—CV
6—UAS
For example, the following command clears all total section statistics for slot 9 line 1:
clrslinetst 9.1 2
Viewing Line Interval Statistics
Interval statistics are collected by each interface for the previous 24 hours of operation. The 24 hours
are broken into 96 15-minute intervals, where interval 1 is the most recent and 96 is the oldest. As time
progresses, the system drops the oldest interval and adds the latest one, creating a sliding 24-hour
window that moves with time.
