Analyzing the Signaling Trace Messages

Analyzing the Signaling Trace Messages

The signaling trace function enables you to analyze trace messages by viewing trace message list, viewing time sequence diagram and message explanations, filtering and comparing trace messages, and exporting subscriber trace messages.

Viewing the Signaling Tracing Message List

Besides the sequence diagram, you can view the trace message list in eSight to view the trace results of messages transmitted between NEs.

Prerequisites
  • One or more trace tasks that have collected messages exist on the eSight.
  • The time of each NE needs to be synchronized. Otherwise, signalings may be displayed in a wrong sequence.
  • You have the Management operations of Signaling Trace and Export operations of Signaling Trace rights.
Context

When the disk usage of the eSight reaches 90%, the earliest signaling trace messages stored on the eSight will be automatically deleted until the disk usage reduces to 85%. When this mechanism is used, users may not obtain the required historical signaling data.

Procedure
  1. Choose Resource > Collaboration > Network Element Device Management from the main menu.
  2. Choose Network Element Device Management > Unified Communications > Signaling Trace from the navigation tree on the left.
  3. In the task list, click the hyperlink of a task name.
  4. In the first drop-down list on the left of the page, select List.

    The eSight displays the parsed signaling data as a list, as shown in Figure 13-45.

    Figure 13-45 Signaling List
    NOTE:

    The signaling list page displays the latest 200 signaling messages in the signaling list. You can select the number of signaling messages to be displayed on one page from the drop-down list in the lower left corner.

Follow-up Procedure

You can perform routine maintenance operations on the trace result page, as listed in Table 13-66.

NOTE:

The Show NE local Time, Show Server local Time, and Realtime Refresh are not applicable to imported trace tasks.

Method

Adjusting the signaling sequencing mode

By default, the eSight displays the latest signaling in the signaling message list home page. Choose Latest signaling displayed first or Earliest signaling displayed first from the third drop-down list on the left area of the page to adjust the signaling sequencing mode.

  • Latest signaling displayed first: The latest signaling is displayed in the signaling message list home page.
  • Earliest signaling displayed first: The earliest signaling is displayed in the signaling message list home page.

Displaying NE local time

Select Show NE local Time. The Time in the trace result list is displayed by NE local time.

Displaying server local time

Select Show Server local Time. The time in the trace result list is displayed by time of the time zone where the eSight server is located, which is converted based on the time in the messages transmitted by NEs.

Displaying server local time

For the tasks in the Running state:

  • Select Realtime Refresh. Existing trace messages of the tasks can be viewed and new trace messages can be viewed in real time.
  • Clear Realtime Refresh. Only existing trace messages of the tasks can be viewed.

Filtering messages

You can set filter criteria as required to query trace messages that you focus on. Perform the following operations:

  1. Click Filter in the upper part of the page.
  2. Set the filter criteria.
    NOTE:

    The same trace result page supports the filtering memory function, that is, it memorizes the previous filter criteria. You can modify the filter criteria based on requirements. When you close the current trace result page and open it again, the page does not memorize the previous filter criteria.

  3. Click Confirm.

Saving the trace result

  • Non-anonymization saving: Choose Save HTML and TMF/PTMF File in Plaintext, Save HTML File in Plaintext, Save CAP File in Plaintext, or Save TMF or PTMF File in Plaintext from the Save results drop-down list in the upper part of the page to save the trace result in non-anonymization mode to the specified directory, which facilitates viewing.
  • Anonymization saving: Choose Save HTML and TMF/PTMF File Anonymously, Save HTML File Anonymously, Save CAP File Anonymously, or Save TMF and PTMF File Anonymously from the Saveresults drop-down list in the upper part of the page to save the trace result in anonymization mode to the specified directory, which facilitates viewing.
NOTE:
  • The files exported in anonymized mode include device IP addresses. If the files need to be transferred out of the customer network, you must obtain the permission from the customer first.
  • Decompress the package that contains HTML trace results. Then, click start.bat in the folder to view trace results offline.
  • Signaling data in HTML files trace results can be filtered when you are browsing it in offline mode. The detailed operations are as follows:
    1. Decompress the saved package. Then, click start.bat in the folder.
    2. Click Filter in the upper right corner of the page.
    3. Set the filter criteria.

      The same trace result page supports the filtering memory function, that is, it memorizes the previous filter criteria. You can modify the filter criteria based on requirements. When you close the current trace result page and open it again, the page does not memorize the previous filter criteria.

    4. Click Confirm.

Viewing the historical signaling

You can click the Historical Signaling drop-down list and select the number of historical signalings to be queried. A new page displays the historical signalings before the current signaling point.

You can also perform the previous operations on the new page.

  4. In the first drop-down list on the left of the page, select Sequence diagram.

    The eSight uses the sequence restoration algorithm to restore signaling based on the parsed signaling data and displays the restored signaling in a sequence diagram, as shown in Figure 13-46.

    Figure 13-46 Signaling sequence diagram
    NOTE:
    • The signaling sequence diagram is updated in real time every 10 seconds.
    • The signaling sequence diagram page displays the latest 200 signaling messages in the signaling list. You can select the number of signaling messages to be displayed on one page from the drop-down list in the lower left corner.
    • If interacting with traced NEs, the icons of the NEs that do not support signaling trace, NEs that the eSight does not manage, and third-party NEs are displayed as question marks in the sequence diagram. You can click Enter an NE name below these NE icons and add names for them in the displayed dialog box. After names are added to these NEs, the icons of the NEs in the sequence diagram changes to the customized icon , below which the added NE names are displayed.
    • If the same name is set for the NEs whose icons are displayed as question marks (?) in the sequence diagram, the NE icons are combined to one customized NE icon after the sequence diagram page is opened next time or is manually refreshed. Below the customized NE icon, the NE name and multiple IP addresses are displayed.
