DLP-G132 Refresh PM Counts at One-Day Intervals
Step 2 Click the Performance tab.
Step 3 If you want to change the PM interval to 15 minutes for a subtab, click the relevant subtab(s), located
along the left side of the Performance tab.
Note Performance subtabs vary, depending on the card viewed.
Step 4 If you want to change the PM interval to 15 minutes for a specific port, select the port from the Ports
drop-down list (where available).
Step 5 Go to any of the tabs, subtabs, or ports (found in the Ports drop-down list where available) for that card
where you want to set the PM count interval by clicking on the desired subtab and choosing the port from
the drop-down list.
Step 6 Click the 15 min radio button.
Step 7 Click Refresh. PM parameters appear in 15-minute intervals synchronized with the time of day.
Step 8 View the Curr column to find PM counts for the current 15-minute interval.
Each monitored performance parameter has corresponding threshold values for the current time period.
If the value of the counter exceeds the threshold value for a particular 15-minute interval, a threshold
crossing alert (TCA) is raised. The number represents the counter value for each specific PM parameter.
Step 9 View the Prev-n columns to find PM counts for the previous 15-minute intervals.
Note If a complete 15-minute interval count is not possible, the value appears with a yellow
background. An incomplete or incorrect count can be caused by monitoring for less than
15 minutes after the counter started, changing the node timing settings, changing the time zone
settings, replacing a card, resetting a card, or changing port service states. When the problem is
corrected, the subsequent 15-minute interval appears with a white background.
Step 10 Return to your originating procedure (NTP).
