# Troubleshoot workflows

# Troubleshoot workflows {#ariaid-title1}

Troubleshooting tools for workflows enable administrators to isolate execution paths,
compare contexts, and track incomplete activities.  
Important:  
As of the Zurich release, new customers no longer receive the legacy workflows created and published by ServiceNow, Inc.. All legacy workflow functionality has been replaced by Workflow Studio content. Only customers who upgraded from prior versions retain the ability to use and edit existing legacy workflows. While all customers retain the ability to create legacy workflows, you are strongly encouraged to instead use Workflow Studio to create process automation content. Only Workflow Studio will receive new features and enhancements.

The workflow timeline provides a visual representation of the workflow, including transitions
and the elapsed time for each activity. A troubleshooting tool for highlighting execution paths
helps users perform forensics on a workflow. The highlighting feature can group multiple
execution paths in various colors and can isolate [rollback](https://www.servicenow.com/docs/Qky4wKvqADvrEcX5M7sA6A "Approval and rollback activities generate and manage approvals.") processing. Use the workflow highlighter to isolate incomplete tasks and
approvals. You can also enable a workflow performance timing feature to troubleshoot slow
workflows.

## Execution path troubleshooting in timelines {#ariaid-title2}

Use the controls in a workflow timeline to isolate specific execution paths or compare
multiple execution paths over time.

Timelines show how the activities in the workflow progressed in relation to one another over
time. Isolate execution paths and follow transition lines between subflows and the main flow.
Processing times provide a view of the workflow that you cannot get from the workflow diagram.
Tooltips give precise information about each activity, such as duration.

## Execution history table {#ariaid-title3}

Highlight execution paths and rollbacks to locate activities that may have been left
in an unresolved state.

### About this task

Rollbacks, cancels, and deletions during the execution of a workflow can prevent some
activities from fully completing. Use highlighting in the execution history table to
determine which activities in the workflow were left in an unresolved state.

### Procedure

1. Run the workflow.
2. Navigate to WorkflowAll Contexts.
3. Select a context to troubleshoot.
4. In the Workflow Context form, select the Workflow Activity History related list.
5. Right-click an activity and select Workflow DebugToggle Execution Path Highlighting from the context menu.  
   All activities in that execution path are highlighted in a color selected by
   the platform. The debug path shows all activities that completed
   successfully during the workflow.  
6. Right-click a rollback activity and select Workflow DebugToggle Rollback Highlighting from the context menu.  
   The platform highlights the rollback path (restarted activities) in a
   different color. Each color represents a group of activities that were part
   of the same rollback execution. The highlighting includes the activity that
   initiated the rollback. If you right-click an activity that was not part of
   a rollback, no rows are highlighted.  
   Note:  
   The rollback activity itself appears in both execution path and rollback highlighting.  
7. To remove highlighting, right-click in the list and select an option to clear execution path or rollback highlighting.  
   You can clear individual rollback paths or all rollback highlighting.
