    Viewing Performance Monitoring Details of Optical IPLCs for Detecting and Diagnosing Faults

    To analyze and resolve any faults associated with optical integrated photonic line cards (IPLCs), it is essential to view the diagnostic data, warnings, and alarms for transport performance monitoring. The different types of parameters related to performance monitoring that are retrieved from the optical IPLCs enable you to ensure service availability and verify or monitor individual services and the service network performance.

    The performance monitoring capability in Connectivity Services Director displays information about the health of your network and changing conditions of your optical IPLCs. Use this diagnosis and detection mechanism to identify problems with the equipment, pinpoint security attacks, or to analyze trends and categories of errors. This feature includes fault-monitoring details in the dashboard, in monitoring pages, and on a dedicated page that displays alarms, events, and system log messages that are generated. Performance monitoring parameters can be viewed in both chart and statistical formats. These charts and statistical details provide essential and cohesive information about system conditions, any discrepancies and malfunctioning, and protocols or components that need to be examined and debugged for better efficiency and working capacity. You can assess the performance of your network, not only at a point in time, but also over a period of time. This feature enables you to determine trending and network-health parameters; for example, whether service-level agreements (SLAs) have been violated.

    To view the performance monitoring details of IPLC optics:

    1. From the Junos Space user interface, click the Build icon on the Connectivity Services Director banner.

      The workspaces that are applicable to Build mode are displayed on the Tasks pane.

    2. From the View selector, select Device View.

      The functionalities that you can configure in this view are displayed.

    3. From the Device View pane, click the plus sign (+) next to the My Network tree to expand the tree and select the PTX300 router for which you want to define the optical IPLC settings.

      The network tree is expanded and the selected device is highlighted.

    4. From the Tasks pane, select Device Management > View Physical Inventory.

      An image of the device is displayed on the right pane.

    5. In the image of the device, select an optical IPLC in the image of the device—for example, an optical integrated photonic line card (IPLC) installed in a PTX3000 router.

      The Component Info dialog box is displayed. At the lower part of the dialog box, the Equipment, Status/Config, Performance, and Line Connectivity tabs are displayed.
