The Workflow Builder offers several useful options designed to support and facilitate both troubleshooting published Workflows and testing Draft versions before publishing. This topic explains how to work with these options:

​
Reviewing Workflow Runs

Workflow runs are logged by date and time and listed in the m3ter Console. You can view the runs performed for a m3sh Workflow or open individual Workflow runs and drill in to review run log details:

​
Viewing Workflow Runs

To view m3sh Workflow runs:
  1. Select m3sh:
M3sh Main Nav1
  • The Workflows page opens.
  1. Select the Name hotlink text of the Workflow you want to view runs for. The Workflow opens in Draft mode.
  2. Scroll down to the to the Latest workflow runs panel:
M3sh Automation270
  • Workflow runs are designated and tracked using the UTC date/time when the run started. The Latest workflow runs panel lists the ten most recent runs in descending order of start date/time, and for each run listed you can:
    • Read off the Start time, Trigger, and Status.
    • You can select the Start time hotlink text to open the details page for an individual run - see the following Reviewing Workflow Run Logs section.
    • Filter the list by Status, for example to show only ERROR runs:
M3sh Automation271
  1. Select View all. The Runs page for the Workflow opens:
M3sh Automation272a
Tip: Accessing Workflow runs? Depending on the Workflow set up, there can be other ways to access and review Workflow runs:
  • If a Workflow uses a Notification rule as its trigger, you’ll be able to open runs from the Notification rule details page.
  • If a Workflow is associated with another m3ter entity - such as a Bill or an Account - then you’ll be able to access runs from the entity details page - such as Bill details. The metadata card for an entity will also show hotlink texts you can use to open runs.

​
Reviewing Workflow Run Logs

You can quickly open an individual Workflow run and review detailed run logs on a step-by-step basis. This is useful when troubleshooting Workflow runs that have failed to complete and show an error. To review individual m3sh Workflow run logs:
  1. Select m3sh:
M3sh Main Nav1
  • The Workflows page opens.
  1. Select the Name hotlink text of the Workflow you want to review run logs for. The Workflow opens in Draft mode.
  2. Scroll down to the to the Latest workflow runs panel:
  • If the Workflow run you want to review run logs for is listed, select the Start time hotlink text of the run. The Workflow Runs page opens.
  • If the Workflow run you want to review run logs for is not listed, select View all. The Runs page opens listing all Workflow runs. Select the Start time hotlink text of the run you want to open and review. The Workflow Runs page opens:
M3sh Automation273a
  • The Start time and Status of the run are shown.
  • You can use the controls to zoom in/out or fit to view.
  • In this example, we’ve opened a Workflow run that is showing as in ERROR and a Message is provided to help debugging.
  1. If you want to inspect the log details for a specific step, select the details icon for the step. For example, for the Workflow Start:
M3sh Automation274a
  • The log details for the selected step that was performed in the Workflow run are loaded into the right-hand side of the Run log.
  • In this example, the JSON returned for the billing.balanceamount.updated Event that triggered the Workflow run is loaded.
  1. Similarly, you can review the log details for a functional step performed in the Workflow run:
M3sh Automation275a
  • In this case, the HTTP REQUEST performed by a m3ter API function is shown and you can expand the call to inspect the Request and Response JSON.
  1. To identify and resolve the error with this example run, if we check through the remaining Workflow steps, we find that the final Create AccountPlan m3ter API function is showing an error flag and are told that no logs are available:
M3sh Automation276a
  1. If we now open the Function details for this step, we see that it is configured to use oldAccountPlan for Request Path:
M3sh Automation277
  1. When we open the previous function the error is confirmed as a configuration mismatch, since this previous function has stored the Account to be created under newAccountPlan in the Workflow state:
M3sh Automation278a
  • In an attempt to resolve the error, in the Draft version we can edit the Create AccountPlan function and update it to use newAccountPlan for Request Path.
  • To test this fix and before publishing it to the Workflow, we can enable traffic-forwarding to the Draft version and check the next run - see the following section for details.

​
Enabling Traffic-Forwarding

You can enable traffic-forwarding to the Draft version of a Workflow. This will temporarily switch traffic so that the Draft version of the Workflow will be triggered and run instead of the Published version allowing you to test any Draft updates. The traffic-forwarding option is very useful when you’ve deployed a Published Workflow to production and:
  • You’re in the process of updating a Draft version of the Workflow to add more functionality for a planned new version of the Workflow. As you do this, you can test your updates incrementally and before publishing.
  • An error has occurred when the Workflow runs. After investigation, you’ve identified a possible cause for the run error and performed a fix in the Draft version. Before you publish the Draft, you can test the fix.
To enable traffic-forwarding for m3sh Workflow runs:
  1. Select m3sh:
M3sh Main Nav1
  • The Workflows page opens.
  1. Select the Name hotlink text of the Workflow you want to enable traffic-forwarding for. The Workflow opens in Draft mode and the default setting of Traffic: Published version is shown:
M3sh Automation280a
  • In this example, we’ve opened a Workflow that showed a run error for the currently Published version. In the previous Reviewing Workflow Run Logs section, this error was investigated and identified as a mistaken Request Path setting in the final m3ter API Create AccountPlan function. An attempted fix has been made to the final function in the Draft version:
M3sh Automation282
  • The Request Path update in the Draft has been saved but not yet pushed through to the Published version:
M3sh Automation283
  • We can now enable traffic-forwarding and test the attempted fix in the Draft version
  1. On the drop-down menu select Enable traffic-forwarding:
M3sh Automation284
  • A confirmation dialog shows:
M3sh Automation285
  1. Select Enable traffic-forwarding to confirm the traffic switch. The Workflow’s traffic flag updates:
M3sh Automation253
  • When the Workflow is next triggered, it will run for the Draft version.
  1. You can wait until the relevant Event Notification or Incoming Webhook next triggers the Workflow and then check the Latest workflows runs to see if the Draft Workflow has completed successfully:
M3sh Automation287
  • For the current example, we can see that an Event Notification has triggered the latest run for the Draft version and the run has completed without error. When we open the run to check logs the error showing for the final function is now fixed:
M3sh Automation288a
  1. Return to the Workflow Draft and Publish draft. When you do this, traffic will be automatically switched back to Traffic: Published version default.
Important! When you publish a Workflow Draft version, the Draft is permanently deleted. If you’ve been using the traffic-forwarding feature to perform test runs of a Workflow using the Draft version before publishing, this means any Draft runs will no longer be available.

​
Replaying Workflow Runs

You can replay a Workflow run using the same Event Notification or Incoming Webhook trigger responsible for the original run. Replay runs are clearly identified and this capability is especially useful when testing new Workflow designs or troubleshooting failures in existing Workflows without having to re-trigger runs from external systems. To replay m3sh Workflow runs:
  1. Select m3sh:
M3sh Main Nav1
  • The Workflows page opens.
  1. Select the Name hotlink text of the Workflow you want to view replay runs for. The Workflow opens in Draft mode.
  2. To open the Workflow run you want to replay, on the Latest workflow runs panel either:
  • Locate the run and open it.
  • Select View all to open the Runs page for the Workflow, locate the run, and open it:
M3sh Automation289a
  • In this example of an Event Notification Workflow, we’ve opened a run that is in error. By reviewing the run logs and the error message provided, we’ve identified an error with the Request Path defined for an Create AccountPlan function used for the final step of the Workflow.
  1. In an attempt to fix this error, we can open the Draft and update the Create AccountPlan function to change the Request path setting and then Publish draft. The Published version of the Workflow now has what we believe to be the required fix:
M3sh Automation290
  1. We can now go back to the original Workflow run page and select Replay run. A confirmation dialog opens:
M3sh Automation291
  1. Select Replay run to confirm. The run is replayed using the original run’s trigger payload and a message shows to confirm success.
  2. If we return to the Workflow’s Latest workflows runs panel, we can see the run which is clearly marked as a REPLAYED run:
M3sh Automation292
  1. If we now open the replayed run, we can see that our fix worked and the Workflow run completed without error:
M3sh Automation293a
  • Note that a link is provided to View original run if you need to perform further comparison for checking and debugging.
