Viewing a log of the job event

During processing, the JPS writes the information about the event to a log file. You can view this file on the Log tab of the Job details page. The job log can be helpful in monitoring individual jobs as they occur and in troubleshooting failed jobs. In addition to the job-processing information, the log also includes information from the JPS itself, such as messages from the relevant processing server.

The log consists of separate messages for each step of the event, with the most recent messages appearing at the top. If the process is still running, the log will be updated automatically with any new messages that occur.

Messages are any of the following types:

Critical
Debug
Error
Info
Warning

You can filter the messages by type. That is, on the toolbar, you can select or clear the check box of each type to filter the display.

Each message has a date-and-time stamp of the event. You can also click Show button ) to view more information, such as:

Category: logging category
Thread: name of the thread that created the category
Stack Trace: stack trace from an exception caused by Java or Python (error)
File: name of the program (source file) that produced the message
Line: line number of the source file that generated the message
Level: logging level

The format of the log content is displayed according to the type selected in the Algorithm Display list on the toolbar. To change the display, click the list, and then select the format you want. You can select from the following:

JSON
Text
Python

You can also export the log to a Microsoft Excel spreadsheet or to a text file. To export to Excel, on the toolbar, click XLS, and then open or save the file. To export to a text file, click TXT. The log opens in your browser. You can then save the file from the browser.
