Monitoring the Service Summary Details of E-Line Services for Optimal Debugging

 

You can view the Service Summary page of a particular service to display the consolidated and cumulative status of a service. The overall information pertaining to the service that you can obtain from the different widgets displayed on this page enables you to navigate to the appropriate device or service settings page and modify the configuration parameters appropriately. You can view the connection between the different endpoints and also examine the statistics on the packets and bytes traversing through the endpoints. Using the Service Summary page, you can also select the source device for which you want to view the transport metrics and the traffic statistics on the other pages displayed in Monitor mode for the specific service. This page enables you to obtain an effective graphical view in the form of tables of statistics and charts to view the health and performance of devices and services in your network, which enables you to analyze and troubleshoot the parameters that are causing traffic-handling errors.

Note

The values and statuses of the parameters displayed in the graphs and tables of different widgets are refreshed, based on the polling interval configured on the Monitoring tab of the Preferences page (accessible by clicking the down arrow beside the System button on the Connectivity Services Director banner and selecting Preferences).

To view the Service Summary page for E-Line services:

  1. Select Service View from the View Selector.

    The workspaces that are applicable to routing and tunneling services are displayed on the View pane.

  2. From the Junos Space user interface, click the Monitor icon in the Connectivity Services Director banner.

    The functionalities that you can configure in this mode are displayed on the task pane.

  3. From the Service View pane, on the left, click the plus sign (+) next to Network Services to expand the tree and display the different service types that you can configure.

    The Network Services tree is expanded and displayed on the View pane.

  4. Click the plus sign (+) beside Connectivity to view services based on protocols.
  5. Expand the E-Line Services tree to select an E-Line service.
  6. From the main display area, click the ServiceSummary tab. The Service Summary page is displayed.
Note

The Service Monitoring Summary page is displayed, if you do not select a particular service from the Service View pane and select the E-Line Services term in the Service View pane. The Summary page displays a consolidated view of all of the service instances for a particular service type. The customer associated with the service, type of service, service definition upon which the service order is based, the traffic rate in bits per second, and the traffic trend are displayed. Select the corresponding service from the Network Services > Connectivity tree on the View pane to navigate to the Service Summary page.

Service Status

This widget displays the cumulative, consolidated status of services, such as E-Line. The following fields are displayed in a tabular form in this widget:

  • Name—Name of the service.

  • Type—Protocol configured for the service, such as ELINE, E-LAN, or IP

  • Status—Whether the service is up or down.

  • PEs (Up/Down)—Number of provider edge devices that are in the up and down states

  • UNIs (Up/Down)—Number of user-to-network (ingress) interfaces that are in the up and down states

  • OSPF Neighbors—Number of OSPF neighbors

  • BGP Neighbors—Number of BGP neighbors

  • Local Switch—Whether the local switching mode to terminate multiple Layer 2 circuit pseudowires is configured.

  • Y1731 Status—Whether the connectivity fault management (CFM) profile is configured for the service and whether performance monitoring (PM) statistics collection, such as one-way delay measurement and variation, two-way delay measurement and variation, or loss measurement are configured.

Click Refresh at the top of the monitor to update and display the contents of the table.

The Service Status monitor is also applicable for an E-Line service with any one endpoint as an unmanaged device. For an E-Line service, with unmanaged devices, the overall service status, PEs up/down, UNIs up/down, that are based on polling of only managed devices are displayed.

Connections

This monitor shows the status of connections between peer devices. In the tabular view, the row represents the source device and the columns denote the neighboring and destination devices. A green up-arrow in the indicates that the adjoining device in the network path to the destination device is operationally up. A red down-arrow indicates that the device is down. For the device for which the connection status is displayed, a value of NA is displayed under its own corresponding column to denote that it is not applicable. Click Refresh at the top of the monitor to update and display the contents of the table.

One of the following values is displayed on the columns that denote the adjacent and destination devices or endpoints:

  • PR—Peer Device or Primary-Backup Pair. No Connection such as A/A or Z/Z.

  • PBK—Peer Backup. No Connection.

  • OL—No advertisement has been received for this virtual circuit from the neighbor. There is no outgoing label available for use by this virtual circuit.

  • NA—Not available.

Mouse over the cells in the table to display the description of the connection statuses, such as PR, PBK or NA.

With an E-Line service that contains an unmanaged endpoint, the Connections matrix represents the status from managed to unmanaged devices, based on the managed device polling. The connection status from unmanaged to managed is always displayed as NA.

Traffic Summary

This widget displays the total number of egress packets (packets that are sent out) or traffic passing through all the UNI or customer-edge (CE) interfaces associated with the particular service. This monitor is applicable for E-Line services. The date and time at which the page was last updated is shown. A line graph is displayed with time on the horizontal axis and the number of output packets on the vertical axis.

From the Time Interval drop-down box, select 1 Hour, 8 Hours, 1 Day, 1 Week, 1 Month, 3 Months, 6 Months, 1 Year, or Custom to specify the duration for which the data polled from devices needs to be displayed. If you select the Custom option, the Time range popup dialog box is displayed. Specify the date from the calendar, and select the Time From (Start time in the 24-hour time format of collection of data), and Time To (End time in the 24-hour time format of collection of data). Click OK to save the settings. Else, click Cancel to discard the configuration.

For an E-Line service with one endpoint as an unmanaged device, the Traffic Summary monitor represents the total egress traffic trend of only the managed devices. Unmanaged device traffic is not monitored.
