Errors, warnings, and other information generated as the job runs are stored in logs. You can specify how much information is in a log and whether the log is cleared each time through the Options section of this window. You can also enable safe mode and specify whether PDI should gather performance metrics. Logging and Performance Monitoring describes the logging methods available in PDI.
| Option | Description |
|---|---|
| Clear log before running | Indicates whether to clear all your logs before you run your job. If your log is large, you might need to clear it before the next execution to conserve space. |
| Log level | Specifies how much logging is performed and the amount of information captured:
Debug and Row Level logging levels contain information you may consider too sensitive to be shown. Consider the sensitivity of your data when selecting these logging levels. See the Administer Pentaho Data Integration and Analytics document for instructions on how best to use these logging methods. |
| Enable safe mode | Checks every row passed through your job and ensure all layouts are identical. If a row does not have the same layout as the first row, an error is generated and reported. |
| Start job at | Specifies an alternative starting entry for your job. All the current entries in your job are listed as options in the dropdown menu. |
| Gather performance metrics | Monitors the performance of your job execution through these metrics. Using Performance Graphs shows how to visually analyze these metrics. |
