    Understanding Customer Monitoring Tasks in the cCPE Selfcare Portal

    The Monitoring task group enables you to monitor network statistics, and audit and view graphical data on a per-customer basis. Figure 1 shows an example of the service provider Monitoring view.

    Figure 1: cCPE Selfcare Application Service Provider Monitoring View

    From the Monitoring task group you can perform the following tasks:

    • Perform functional audits
    • Monitor the status of your cCPE customers
    • View historical data
    • Monitor active devices

    Functional Audit Overview

    The Functional Audit task enables you to verify the connectivity between different cCPE customer sites. A functional audit verifies that a site is reachable by sending a series of pings from the source site’s access links to the destination site’s access links. You can select multiple sites for both the source and destination sites. The destination site does not send any pings. A site cannot ping itself, and the functional audit cannot be used if a customer has only one site.

    Figure 2 shows an example of a functional audit.

    Figure 2: Functional Audit Example

    Functional Audit Example

    You perform a functional audit by first selecting the customer and then selecting the source and destination sites between which you want to test the connectivity. The job for the functional audit is placed in the Junos Space Network Management Platform Jobs queue. When the audit completes, the results display:

    • Source access links that were tested
    • Destination access links that were tested
    • Connection status (up or down)
    • Percentage of packets dropped
    • Round trip time measured in milliseconds (ms)
    • Start time the audit was scheduled

    If the connection status is down, or if one of the access links is configured incorrectly, the percent dropped will be 100 and the round trip time displays N/A. The system keeps a record of the 10 most recently scheduled audits. After performing 10 audits, the system drops information for the oldest audit after a new audit is performed. When you schedule a functional audit it is added to the Jobs queue. If the job fails, a failure message is displayed. Contact your cCPE service provider if you encounter an error.

    Error messages differ depending on whether you are running the cCPE Selfcare application on the Junos Space Network Management Platform or whether you have integrated the Selfcare application APIs with your OSS. Error messages are described in Table 1 and Table 2.

    Table 1: Job Failure Messages When Running the cCPE Selfcare Application on the Junos Space Network Management Platform

    Error Message

    Meaning

    Error when attempting to gather information of provided sites

    System was unable to gather and verify the site information for the selected source and destination sites.

    No links given to ping

    Destination site has no access links.

    The origin site has no access links

    Source site has no access links.

    Job failure on pinging access link {access-link name}

    Ping was attempted, but an error occurred that stopped the job from succeeding. This error can occur if the Junos Space Network Management Platform does not receive a response from the device or because the system was unable to add the result to the database.

    Job failure on pinging access links and updating job progress

    System tried to update the progress of the job, but failed.

    Job failure on setting up job

    System tried to get the customer and source site information from the database but failed, or the system was unable to reach the job manager. This error occurs prior to any pings being attempted.

    Table 2 describes the job failure messages if you integrate your OSS using the Selfcare portal APIs.

    Table 2: Job Failure Messages when Running the cCPE Selfcare Application on an OSS

    Error Message

    Meaning

    Error when attempting to gather information of provided sites

    System tried to check the provided sites, or when the system tried to retrieve a list of sites from the database, an error occurred. This error can occur if the sites you provided do not belong to the customer, or you did not provide an ID for every site.

    No links given to ping

    Destination site has no access links.

    The origin site has not access links

    Source site has no access links.

    Job failure on pinging access link (access-link name)

    Ping was attempted, but an error occurred that stopped the job from succeeding. This error can occur if the OSS does not receive a response from the device or because the system was unable to add the result to the database.

    Job failure deleting old audits

    System tried to delete the older audits, but failed. In this case the new audits are added to the database, but the older audits remain.

    Job failure on pinging access links and updating job progress

    System tried to update the progress of the job, but failed.

    Job failure on setting up job

    System tried to get the customer and source site information from the database but failed, or the system was unable to reach the job manager. This error occurs prior to any pings being attempted.

    Status Monitoring Overview

    The Status Monitoring task enables you to select a cCPE customer and a site and display traffic information for all access links associated with the site. The counters displayed are retrieved directly for the devices managed by the Junos Space Network Management Platform and associated with the selected customer and site.

    Figure 3 shows an example view of the Status Monitoring page.

    Historical Data Overview

    This Historical Data task enables you to select a cCPE customer and a site and generate various charts that show the customer data on the access link associated with the site. You can choose which graphical format you want to use to display this data based on the MIB selection and time interval for the graphed data. Charts are retrieved from OpenNMS in the Junos Space Network Management Platform.

    Figure 4 shows an example view of the Historical Data page.

    Active Devices Monitoring Overview

    The Active Devices Monitoring task enables you to select a cCPE customer and a site and view the MAC and IP addresses of client devices that are active in the network connected by the access link. This information is stored in the Address Resolution Protocol (ARP) tables of the device and retrieved through the Junos Space Network Management Platform.

    Figure 5 shows an example of the view Active Devices Monitoring page.

    Figure 5: Active Devices Monitoring Page

    Active Devices Monitoring Page

    The results of the Active Devices Monitoring task display three columns:

    • Name of the access link
    • IP address
    • MAC address

    In the example shown in Figure 5, the access link called Primary is connected to a network with multiple client devices, each device has a unique IP address and MAC address. If there are no active clients using the access link, there may be no information in the device’s ARP table, and the results will display “No data found”. If the application encounters an error, or is unable to reach the client device, the results will display “Problems accessing router configuration”.
