Packet data mining tasks

NAM Server ► Tools ► Packet data mining tasks opens the Smart packet capture screen.

Tip

This screen is part of Smart Packet Capture.

Use the Smart packet capture screen to list each Smart Packet Capture previously made, still in progress, or still scheduled to run. See Smart Packet Capture for an overview.

The Smart packet capture screen displays tasks from all users, not only the current user.

  • Type part of a task name in the box to list only the tasks that match what you typed.
  • Click Collapsed in any task row to display all trace files associated with that task. If nothing is listed, hover the mouse pointer over the status icon to review the status of reporting devices. Click Expanded to collapse the trace list for that task.

The following Smart packet capture example shows two separate tasks, each of which is expanded to show a single capture file:

Tasks

The task name, task description, the user who created the task, the task start time, and time remaining or task duration are all listed for each task. A progress bar shows task process for started or complete tasks.

Unlocked - Indicates that the capture files associated with the task are not password protected.
Locked - Indicates that all capture files associated with the task are password protected. You must supply a password before you can open them.
Task in progress - Indicates that the task is in progress.
Task interrupted - Indicates that the task was interrupted. Hover the pointer over this icon for more information.

Capture reload button - Opens to the report that was used to generate that row's task. From there, you can create a new capture task that will not overwrite the existing task's data. Compare to Capture edit button.

Capture edit button - Opens that row's task in the Edit task window, where you can change the capture parameters and run it again to overwrite the existing task's data. Compare to Capture reload button.

Capture stop button - Stops the task in that row.
You can stop an entire task, which stops all associated file captures, or you can stop a single file capture and leave the rest of the captures running.
If this button is not displayed, either the task has not begun (is scheduled for the future) or it has already finished.

Capture delete button - Deletes the task in that row.

  • If you delete a task, all associated trace files are deleted with it.
  • If you delete the last trace file associated with a task, the task is also deleted.
  • If this button is not available, that task is still running. You cannot delete an active task.

Possible task statuses:

  • Scheduled. Task will start: {time}
    The task has been created but not yet submitted to a device. Hover your mouse pointer over the information icon to see when the task is schedule to start.
  • Capturing traffic
    The task has been submitted to a device and traffic is being captured.
  • Downloading
    Trace files are being downloaded to a NAM Server. Current task progress is shown (overall and per device).
  • Completed
    The task is complete and the trace archive is available for analysis.

Files

There may be more than one file per task.

  • Click Collapsed in any task row to display all trace files associated with that task. For each file within a task, the file source (device type, address, and port number), capture status, and file size are all listed.
    If nothing is listed, hover the mouse pointer over the status icon to review the status of reporting devices.
  • Click Expanded to collapse the trace list for that task.

Capture stop button - Stops capturing the file in that row.

  • Does not stop the entire task. Any other file captures in progress in that task remain running.
  • If this button is not displayed, either the file capture has not begun (it is too soon to stop it) or it has already finished (it is too late to stop it). But you can delete a file.

Capture delete button - Deletes the file in that row.

  • Does not delete any other file captures in that task.
  • If you delete the last (only) trace file associated with a task, the task is also deleted.

Trace Trimmer button - Open the file in that row in Trace Trimmer.

Download button - Downloads the file in that row from the NAM Server.

  • If the task is password-protected, you need to enter the password at this point.
  • If this button is not displayed, either the capture is still running or there was an error in the capture.
