Use this procedure to view performance monitoring parameters in Cisco Optical Site Manager. It helps you complete the required configuration, verification, or management action and confirm the result.

Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds, and report performance data for early problem detection. Users can retrieve current and historical PM counters for various controllers at several intervals.

Description

Auto Refresh for Performance Monitoring Data

Cisco IOS XR Release 26.1.1

You can now enable the auto-refresh option in the Performance tab to automatically update performance monitoring data. After you manually retrieve PM data once, auto refresh ensures future updates reflect the latest current and historical information.

You can set the auto-refresh interval to 15 seconds, 30 seconds, 1 minute, 3 minutes, or 5 minutes.

PM for optical parameters includes laser bias current, transmit and receive optical power, mean polarization mode dispersion, accumulated chromatic dispersion, and received optical signal-to-noise ratio (OSNR). These parameters facilitate troubleshooting operations and enhance the data collected directly from the equipment.

Auto Refresh automatically updates performance monitoring data after manual retrieval, ensuring that future updates reflect the latest current and historical information.

Before you begin
