There are four ways to monitor Tetra Data Pipeline file processing:

• The File Processing page
• The Pipelines page
• The Search Workflow API
• Email notifications

To configure a pipeline, see Set Up and Edit Pipelines.

Monitor and Manage Pipelines by Using the File Processing Page

To monitor pipeline processing, files, workflows, and logs on the File Processing page, do the following:

1. Sign in to the TDP.
2. In the left navigation menu, choose Pipelines. Then, choose File Processing. The File Processing page appears.
3. To find a specific pipeline, do the following:

• To search for a specific pipeline, type the information in the upper left search box. Select 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 select the refresh button next to it to view the latest status.
• Browse the pipelines on the left side of the page and select the one you want to see.

📘

NOTE

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.

3. 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, or Failed) use the filters at the top of the page. You can also choose to simply browse, using the scrollbar as necessary.
4. You can select files by clicking on them one at a time or by selecting several or all of them. 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

There are two tabs in the right panel: Pipeline and Workflow:

• In the Pipeline tab, you can click a link that will take you to a page where you can edit your pipeline, scan for unprocessed files, create a bulk pipeline process job, cancel pending workflow, and view high-level trigger, protocol, and step details.
• In the Workflow tab, 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.

• COMPLETION %—shows how much of the job has been processed.
• STARTED—shows the date and time the job started processing.
• COMPLETED—shows the date and time the job completed.
• PIPELINE—shows the name of the pipeline the job was for.
• INFO—opens a Bulk Processing Job Details dialog that shows the job’s details, including all of the files affected by the operation.

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.

📘

NOTE

Pipeline reprocessing operates on the latest version of an existing file only. No previously deleted files are reprocessed as part of a pipeline reprocessing job.

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

📘

NOTE:

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, do the following:

1. On the File Processing page, select the pipeline that you want to cancel pending workflows for.
2. Select the right pane's Pipeline tab.
3. Choose Cancel All Pending Workflows.

Viewing Trigger, Protocol, and Step Details

In the Pipeline tab on the File Processing page, you can view pipelines' Trigger, Protocol, and Steps 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 Tab to View Workflows, Workflow Histories, Logs, File Properties, and to Manage Files

The Workflow tab provides details on files and workflows. It also allows you to view, download, add attributes (metadata, labels, and tags), and reprocess them.

Upload New File Versions

📘

NOTE

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, do the following:

1. On the File Details page, in the FILE ACTIONS section, select the Upload New Version button. A dialog appears.
2. (Optional) To add labels to the file, select the plus icon in the LABELS row. For more information, see Attributes.

Troubleshooting

A python-exec Pipeline Returns an invalid non-printable character U+00A Error

To resolve invalid non-printable character U+00A errors, check the Python code in your python-exec pipeline configuration for non-printable characters, such as white spaces, carriage returns, tabs, and line breaks. Then, remove the non-printable characters and redeploy the pipeline.
