DLP- D458 Monitor PM Counts for a Selected Signal
• 1 hour
• 1 day
Step 4 Click Refresh. Performance monitoring information appears in the interval selected synchronized with
the time of day.
Step 5 View the Prev column to find PM counts for the latest selected interval.
Each monitored performance parameter has corresponding threshold values for the latest time period. If
the value of the counter exceeds the threshold value for a particular selected interval, a threshold crossing
alert (TCA) is raised. The number represents the counter value for each specific performance monitoring
parameter.
Step 6 View the Prev-n columns to find PM counts for the previous intervals.
If a complete count over the selected interval is not possible, the value appears with a yellow
background. For example, if you selected the 1-day interval, an incomplete or incorrect count can be
caused by monitoring for less than 24 hours after the counter started, changing node timing settings,
changing the time zone settings, replacing a card, resetting a card, or changing port states. When the
problem is corrected, the subsequent 1-day interval appears with a white background.
Step 7 Return to your originating procedure (NTP).
DLP-D458 Monitor PM Counts for a Selected Signal
Step 1 In node view, double-click the card where you want to view PM counts. The card view appears.
Step 2 Click the Performance tab.
Different port and signal-type drop-down lists appear depending on the card type and the circuit type.
The appropriate signal types (DS3i, E1, E3, STM-N line, and VC4) appear based on the selected card.
For example, the STM16 LH AS 1550 card lists the line and VC4 PM parameters as signal types, which
enables you to select both the line and the VC4 within the specified line.
Step 3 In the signal type drop-down lists, click one of the following options:
• Port: n (card port number)
• Line: n (STM line number)
• VC4: n (VC path number within the STM line)
Figure 21-10 shows the Line drop-down list in the Performance window for an STM-16 card.
Purpose This task uses signal-type selections to monitor near-end or far-end PM
counts for specific signals on a selected card and port.
