Interpreting Pipeline and Component Health State

Each pipeline and component within that pipeline returns a health status of HEALTHY, ERROR, "-", No Completed Executions, or No Health Information Available. A pipeline only has a health state after a pipeline component has completed its first execution or if component preconditions have failed. The health status for components aggregates into a pipeline health status in that error states are visible first when you view your pipeline execution details.

Pipeline Health States

HEALTHY

The aggregate health status of all components is HEALTHY. This means at least one component must have successfully completed. You can click on the HEALTHY status to see the most recent successfully completed pipeline component instance on the Execution Details page.

ERROR

At least one component in the pipeline has a health status of ERROR. You can click on the ERROR status to see the most recent failed pipeline component instance on the Execution Details page.

No Completed Executions or No Health Information Available.

No health status was reported for this pipeline.

Note

While components update their health status almost immediately, it may take up to five minutes for a pipeline health status to update.

Component Health States

A component (Activity or DataNode) has a health status of HEALTHY if it has completed a successful execution where it was marked with a status of FINISHED or MARK_FINISHED. You can click on the name of the component or the HEALTHY status to see the most recent successfully completed pipeline component instances on the Execution Details page.

ERROR
