Chapter 14 Monitoring DWDM Properties
Viewing Performance Monitoring Configuration
Step 5 To close the G709 Info Properties window, click the upper right corner.
Viewing Performance Monitoring Configuration
Performance monitoring parameters are used to gather, store, set thresholds for, and report performance
data for early detection of problems. Thresholds are used to set error levels for each performance
monitoring parameter. During the accumulation cycle, if the current value of a performance monitoring
parameter reaches or exceeds its corresponding threshold value, a threshold crossing alert (TCA) can be
generated. The TCAs provide early detection of performance degradation.
Prime Network Vision enables you to view the configuration settings for performance monitoring.
Performance monitoring statistics are accumulated on a 15-minute basis, synchronized to the start of
each quarter-hour. They are also accumulated on a daily basis starting at midnight. Historical counts are
maintained for thirty-three 15-minute intervals and two daily intervals.
To view performance monitoring configuration settings:
Step 1 In Prime Network Vision, double-click the device on which DWDM is configured.
Step 2 In the inventory window, choose Physical Inventory > Chassis and navigate to the interface configured
for DWDM.
Step 3 In the content pane, select the performance monitoring configuration settings you want to view:
• To view the performance monitoring 15-minute configuration settings, click PM 15-min Settings.
• To view the performance monitoring 24-hour configuration settings, click PM 24-hour Settings.
The Client DWDM PM Settings Properties window is displayed as shown in Figure 14-4.
