You can monitor statistics and view log events for a Spark engine mapping job in the Monitor tab of the Administrator tool. You can also monitor mapping jobs for the Spark engine in the YARN web user interface.
The following image shows the Monitor tab in the Administrator tool:
The Monitor tab has the following views:
Summary Statistics
Use the
Summary Statistics
view to view graphical summaries of object states and distribution across the Data Integration Services. You can also view graphs of the memory and CPU that the Data Integration Services used to run the objects.
Execution Statistics
Use the
Execution Statistics
view to monitor properties, run-time statistics, and run-time reports. In the Navigator, you can expand a Data Integration Service to monitor
Ad Hoc Jobs
or expand an application to monitor deployed mapping jobs or workflows
When you select
Ad Hoc Jobs
, deployed mapping jobs, or workflows from an application in the Navigator of the
Execution Statistics
view, a list of jobs appears in the contents panel. The contents panel displays jobs that are in the queued, running, completed, failed, aborted, and cancelled state. The Data Integration Service submits jobs in the queued state to the cluster when enough resources are available.
The contents panel groups related jobs based on the job type. You can expand a job type to view the related jobs under it.
Access the following views in the
Execution Statistics
view:
Properties
The
Properties
view shows the general properties about the selected job such as name, job type, user who started the job, and start time of the job.
Spark Execution Plan
When you view the Spark execution plan for a mapping, the Data Integration Service translates the mapping to a Scala program and an optional set of commands. The execution plan shows the commands and the Scala program code.

Source. The name of the mapping source file.
Target name. The name of the target file.
Rows. The number of rows read for source and target.
