The workflow history page is an important tool to monitor an account and troubleshoot issues. When you first go to the page you will see an up-to-the-minute feed of workflows as they are queued up, in progress, completed, or have failed. You can then click into each execution to view a log of the workflow's execution, including any errors that may have arisen. Each column on the workflow history page is searchable, allowing you to dig into why a workflow failed or did not accomplish the desired outcome. You are also able to re-execute any workflows you'd like via the workflow history page.
