Performance Monitoring

Performance Monitoring

Monitoring the performance of a communication system is part of a proactive strategy that catches problems before they affect service. The MGX 8260 Media Gateway provides performance information for DS1/E1 and DS3 lines.

Monitoring DS1 Performance

You can view current or historical statistics that the system collects on DS1 performance. Current statistics are performance statistics collected over the last fifteen minutes.

Viewing Current T1 Statistics

To view current statistics for a single T1 line, enter the lsds1curst command, specifying the slot and line number, delimited by a period, of the line. The system displays current statistics:

======================================================================= DS1 Line Current Statistics (lsds1curst) ======================================================================= DS1 Slot.Line : 13.1 Path Errored Seconds : 0 Path Severely Errored Seconds : 0 Path Severely Errored Framing Seconds : 0 Path UnAvailable Seconds : 606 Path Control Slip Seconds : 0 Path Code Violations : 0 Path SEF or AIS : 0 Path Bursty Errored Seconds : 0 Line Errored Seconds : 0 Line Severely Errored Seconds : 0 Line Code Violations : 0

To view current statistics for all T1 lines, enter the lsds1cursts command.

The system displays the current statistics summary:

======================================================================= DS1 Current Statistics for all Lines (lsds1cursts) ======================================================================= Slot.Line Error Secs SeverSecs FrameSecs UnAvailSecs ========= =========== ========= ========= =========== 13.1 0 0 0 473 13.2 0 0 0 473 13.3 0 0 0 473 13.4 0 0 0 472 13.5 0 0 0 472

Viewing Total T1 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 T1 line, enter the lsds1totst command, specifying the slot and line number, delimited by a period, of the line. The system displays current statistics:

======================================================================= DS1 Line Total Statistics (lsds1totst) ======================================================================= DS1 Slot.Line : 13.1 Path Errored Seconds : 2 Path Severely Errored Seconds : 0 Path Severely Errored Framing Seconds : 0 Path UnAvailable Seconds : 11162 Path Control Slip Seconds : 2 Path Code Violations : 0 Path SEF or AIS : 0 Path Bursty Errored Seconds : 0 Line Errored Seconds : 11 Line Severely Errored Seconds : 11 Line Code Violations : 0

To view 24-hour statistics for all lines, enter the lsds1totsts command.

The system displays the 24-hour statistics summary:

Viewing Interval T1 Statistics

Interval statistics are collected by each DS1 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.

To list interval statistics for a T1 line, enter the lsds1intst command, specifying the slot and line number, delimited by a period, of the line and the number (1-96) of the interval of interest. The system displays the interval statistics:

To view interval statistics for a single line, enter the lsslineist command, specifying the slot and line number, delimited by a period, and the desired interval. The system displays the interval statistics:

======================================================================= Sonet Line Interval Statistics (lsslineist) ======================================================================= Sonet Line Slot.Line : 9.1 Interval : 1 Errored Seconds : 0 Severely Errored Seconds : 0 Coding Voilations : 0 UnAvailable Seconds : 900

To view interval statistics for all lines, enter the lsslineists command. The system displays interval statistics for all lines:

======================================================================= Sonet Line Interval Statistics for all Lines (lsslineists) ======================================================================= Slot.Line Interval ErrSecs SeverSecs CVSecs UASecs ========= ========= ========= ========= ========= ========= 9.1 1 0 0 0 900 9.1 2 0 0 0 900 9.1 3 0 0 0 900 9.1 4 0 0 0 900 9.1 5 0 0 0 900 9.1 6 0 0 0 900 9.1 7 0 0 0 900 9.1 8 0 0 0 900 9.1 9 0 0 0 900 9.1 10 0 0 0 900 9.1 11 0 0 0 900 9.1 12 0 0 0 900 9.1 13 0 0 0 900 9.1 14 0 0 0 900 9.1 15 0 0 0 900 9.1 16 0 0 0 900 9.1 17 0 0 0 900 9.1 18 0 0 0 900 9.1 19 0 0 0 900 9.1 20 0 0 0 900

Monitoring SONET Path Statistics

Viewing Path Current Statistics

Current statistics are performance statistics collected over the last fifteen minutes. To view current statistics for a single line, enter the lsspathcst command, specifying the slot and OC-3 line number delimited by a period. The system displays current statistics for the specified line:

======================================================================= Sonet Path Current Statistics (lsspathcst) ======================================================================= Sonet Path Slot.Line : 9.1 Path Current Status : c Errored Seconds : 0 Severely Errored Seconds : 0 Coding Voilations : 0 UnAvailable Seconds : 866

To view current statistics for all lines, enter the lsspathcsts command. The system displays the current statistics for all lines:

======================================================================= Sonet Path Current Statistics for all Lines (lsspathcsts) ======================================================================= Slot.Line Error Secs SeverSecs CodingVoilations UnAvailSecs ========= =========== ========= ============= =========== 9.1 0 0 0 896 9.2 0 0 0 477

Clearing Path Current Statistics

To clear statistics, enter the clrspathcst 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 current line statistics for slot 9 line 1:

clrspathcst 9.1 2

Viewing Path 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 lsspathtst command, specifying the slot and line number delimited by a period. The system displays the total statistics for the specified line:

======================================================================= Sonet Path Total Statistics (lsspathtst) ======================================================================= Sonet Path Slot.Line : 9.1 Errored Seconds : 0 Severely Errored Seconds : 0 Coding Voilations : 0 UnAvailable Seconds : 87293

To view total statistics for all lines, enter the lsspathtsts command. The system displays total statistics for all lines:

======================================================================= Sonet Path Total Statistics for all Lines (lsspathtsts) ======================================================================= Slot.Line Error Secs SeverSecs CodingVoilations UnAvailSecs ========= =========== ========= ============= =========== 9.1 0 0 0 87293 9.2 0 0 0 63892

Clearing Path Total Statistics

To clear statistics, enter the clrspathtst 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:

clrspathtst 9.1 2

Viewing Path 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.

To view interval statistics for a single line, enter the lsspathist command, specifying the slot and line number, delimited by a period, and the desired interval. The system displays the interval statistics:

======================================================================= Sonet Path Interval Statistics (lsspathist) ======================================================================= Sonet Path Slot.Line : 9.1 Interval : 1 Errored Seconds : 0 Severely Errored Seconds : 0 Coding Voilations : 0 UnAvailable Seconds : 900

To view interval statistics for all lines, enter the lsspathists command. The system displays interval statistics for all lines:

======================================================================= Sonet Path Interval Statistics for all Lines (lsspathists) ======================================================================= Slot.Line Interval ErrSecs SeverSecs CVSecs UASecs ========= ========= ========= ========= ========= ========= 9.1 1 0 0 0 900 9.1 2 0 0 0 900 9.1 3 0 0 0 900 9.1 4 0 0 0 900 9.1 5 0 0 0 900 9.1 6 0 0 0 900 9.1 7 0 0 0 900 9.1 8 0 0 0 900 9.1 9 0 0 0 900 9.1 10 0 0 0 900 9.1 11 0 0 0 900 9.1 12 0 0 0 900 9.1 13 0 0 0 900 9.1 14 0 0 0 900 9.1 15 0 0 0 900 9.1 16 0 0 0 900 9.1 17 0 0 0 900 9.1 18 0 0 0 900 9.1 19 0 0 0 900 9.1 20 0 0 0 900

Monitoring SONET Alarm Statistics

To view real-time statistics for a single line, enter the lssonetstat command, specifying the slot and line number, delimited by a period. The system displays the following alarm statistics:

======================================================================= Sonet Line statistics (lssonetstat) ======================================================================= Sonet Line : 9.1 Loss of Signal : 472938 Loss of Frame : 0 Line AIS : 472938 Line RDI : 0 Path LOP : 0 Path AIS : 472938 Path RDI : 0 Path SLM : 0 Alarm State : 15 Performance Alarm State : c0c03c
