Monitor Pipeline File Processing

Once pipelines are set up and enabled, they can process files when triggered. There are several ways that you can monitor pipeline processing:

  • View the TDP File Processing Page
  • Use the Workflow Search API
  • Email Notifications

If you'd like some basic information on pipelines before you start, see the Pipeline Overview page.

Use the TDP File Processing Page to Monitor the Pipeline

Pipeline processing can be easily monitored on the File Processing page. This page allows you to monitor pipeline processing, files, workflows, and logs. You can also view and download files and more.

Viewing Pipeline Processing Details and Files

  1. In the TDP, click the hamburger menu and select Pipelines, then File Processing.
  2. Pipelines are listed on the left side of the screen. To find the pipeline you want, do the following.
    • To search for a specific pipeline, type the information in the search box in the upper left corner. Click the drop-down menu to toggle between searching by name or by protocol.
    • Active and historical workflow counts are shown near the top of the window. The active workflow count shows all workflows that are pending or currently being processed. The historical workflow count represents workflows that have been completed or have failed. If workflows are active, you can click the refresh button next to it to view the latest status.
    • Browse the pipelines on the left side of the page and click on the one you want to see. Use the scrollbar if needed.



There might be an overlap between active and historical counts during reprocessing. A previously completed fileID will have a historical record and an active record while it is being reprocessed.


Select a Pipeline to View Processing Details

  1. If you'd like to see a specific file, files that have certain date stamps, or that are of a certain status (All, Pending, In Progress, Completed, Failed) use the filters at the top of the page. You can also choose to simply browse, using the scrollbar as necessary.
  2. You can select files by clicking on them one at a time or by selecting several or all of them. To select the files, click the check box next to the File field label.

File Field Label

For each file, the following information is shown:

  • File Name
  • The number of Output Files, if any are generated
  • File Status (Pending, In Progress, Completed, or Failed)
  • Timestamp of the File Status

The right side of the window has two panels: Pipeline and Workflow.

  • In the Pipeline Panel, you can click a link that will take you to a page where you can edit your pipeline, scan for unprocessed files, and view high-level trigger, protocol, and step details.
  • In the Workflow Panel, you can click links to open workflows, files, and a file workflow history. You can also use it to reprocess files, view workflow logs, manage files, and more.

Using the Pipeline Panel to Access Pipeline Editor, Scan Files, and View Details

The following topics explain how see the Edit Pipeline page, scan for unprocessed files, selected unprocessed files for processing, and view high-level trigger, protocol, and step details.


Pipeline Processing Pipeline Panel

Editing a Pipeline

You can go to the page that will allow you to edit the pipeline by clicking the Edit Pipeline button in the Pipeline Panel. Detailed documentation on how to edit pipelines appears in this topic.

Scanning Unprocessed Files

To scan for unprocessed files in the Pipeline Panel, click the Scan for Unprocessed Files button. The date of the last scan is updated.

Processing Unprocessed Files

To process files in the Pipeline Panel, complete the following steps.

  1. Click Select Processed Files. Files appear in a pop up window.

Selecting Files for Processing

  1. Click the checkboxes to the left of the files you want to process, then click Process Selected Files. Or, click Process All Unprocessed Files to process everything that has not yet been processed.

Note that Retrying and File and Reprocessing a file are very two different terms. For more information on both, see this topic.

Retrying and Reprocessing Files

Retry and Reprocess are two related, but different terms. By default, if there is an error or issue that prevents the processing of a file, the pipeline retries processing three more times before the pipeline fails. This is done automatically, but you can do it manually as well in the TDP Dashboard. Reprocess is starting the process again; it is as if you've re-uploaded the file.

Here is a table that compares both features and explains what happens if you edit the pipeline.

If you configure the pipeline to use another protocol.Still uses the old protocol.Will use the new protocol.
If you force overwrite the protocol (and the protocol version stays the same)Will use the force-written protocol.Will use the force-written protocol.
If the protocol refers to a wildcard version of a task-script e.g. 1.x and you upload a bumped minor version of the task-script.Will use the new task script version.Will use the new task script version.
If you force overwrite a task-script (and the script version stays the same).Will use the force-written script.Will use the force-written script.
If you update the pipeline config value directly in the pipeline design page.Still uses the old pipeline config value.Will use the new pipeline config value.
If you update a non-secret pipeline config value on Shared Settings page.Still uses the old pipeline config.Will use the new pipeline config.
If you update a secret pipeline config value on Shared Settings page.Will use the new secret value in most cases (see note below)Will use the new secret value.



If you update a secret pipeline config value on the Shared Settings page, the secret is resolved when you create a new task instance, and it can only get the latest secret from SSM Parameter Store. If the workflow still uses an existing task instance, it will use the old secret. On the other hand, if the workflow creates a new task instance, it will use the new secret. The reason for this is that secret only appears in SSM or task instance, and the software doesn't copy the secret value anywhere else, so when you retry the workflow, it can only get a secret reference, not the real value.

Canceling Pending Workflows

To cancel pending workflows, in the Pipeline screen, click the Cancel all pending workflows button

Viewing Trigger, Protocol, and Step Details

In the Pipeline Panel, view the Trigger, Protocol, and Step details.

  • The Trigger shows the criteria that must be met for the pipeline to process a file.
  • The Protocol shows the following:
    The namespace is a combination of which organization the file belongs to and who can use the file. Namespaces are discussed in detail in this topic.
    The slug is the unique name of the protocol. Slugs are discussed in detail in this topic.
    * The version shows the version number of the pipeline used.
  • The Steps show the name of each step that is part of the pipeline workflow.

Using the Workflow Panel to View Workflows, Workflow Histories, Logs, File Properties, and to Manage Files

The Workflow panel provides details on files and workflows. It also allows you to view, download, add attributes (metadata, labels, and tags), and reprocess them. This panel becomes visible when you select one or more files from the list in the center of the page. You can also view and download files from this panel.

Uploading New File Versions



When a new file version is uploaded, the TDP copies all file metadata from the previous file version, including workflow data. The system then uses this information to relate the new file version to the workflow that created the previous file version. This process results in the new file version being displayed on the File Details page and showing that the new, uploaded file version was produced by a workflow.

To upload a new file version, complete the following steps.

  1. Click "AddNew Version". The Upload a New File Version screen appears.
  2. If desired, add a label. Labels are explained in detail in this topic. To add a label, click the Add New Label link, then add the Label Name and Label Value. For more information on accepted values, see this topic.
