Workflow Logs
The Data Integration Service generates log events when you run a workflow. Log events include information about workflow errors, task progress, and the setting of workflow variables. Log events also include the analyses of the links that the Data Integration Service evaluates in a sequence flow.
If a workflow instance includes a Mapping task, the Data Integration Service generates a separate log file for the mapping. The mapping log file includes any errors encountered during the mapping run and load summary and transformation statistics.
You can view the workflow and mapping logs from the Monitor tab.
When you recover an interrupted workflow instance, the Data Integration Service appends log events to the current workflow log. When the recovered workflow instance includes a Mapping task that is restarted, the Data Integration Service creates a mapping log.
If the workflow runs on a grid, the recovery of the workflow instance might run on a different node than the original workflow instance run. If the recovery runs on a different node and the log directory is not in a shared location, the Data Integration Service creates a log file with the same name on the current node.
Workflow Log Information
The information in the workflow log file represents the sequence of events that occur when the workflow runs.
The Data Integration Service writes information to the workflow log when the following types of event occur:
- •The Data Integration Service starts to run a task or another object in the workflow.
- •A task or another object in the workflow is in progress.
- •The Data Integration Service finishes running a task or another object in the workflow.
- •The Data Integration Service sets or updates a workflow variable.
- •The Data Integration Service evaluates the links in a sequence flow and identifies the correct path for the workflow process.
- •The workflow encounters a workflow error.
