About the Log Files tool

Select the > System > Operations > Logs menu item to access the Log Files tool. Here you can view or download the current Pega log, Security log, Alert log or other logs on the server node you are accessing.

Types of logs

Which logs appear depend on the contents of the prlogging.xml file for this node. You may see the following:

PEGA — A text file containing warnings, errors, and information messages about internal operations
ALERT — Performance-related alerts triggered by prconfig settings (or implicit, default values.) A text file with fields separated by single asterisk character. User the PLA tool to parse and summarize this file into a Microsoft Excel spreadsheet. See Understanding Alerts.
ALERTSECURITY — Alerts (identified by the prefix SECU) that suggest improper configuration of Internet Application Composer facilities, or overt attempts to bypass system security features through URL tampering. See Understanding Alerts.
BIX — Log files created during extract operation rules by the optional Business Intelligence Exchange product.
SERVICES-PAL — A Comma-Separated-Values file with performance data saved from services. See Performance tool — Statistics for services in the SERVICES-PAL log.

Viewing the logs

Click a file name to view one of the logs. Typically the date portion of the file name indicates that this file contains only log

The initial display shows only lines of the log for your own Operator ID (for all your sessions on this node), in pages of 25 lines each. Click a number at the bottom of the display to see the corresponding page, or next to see the next group.

Options

Click the Options link to view or set log filtering criteria. Click Apply to review the log again with updated criteria, or Back to return to the initial window with no changes.

Field	Description

Application server authentication may be required. Access is controlled by the PegaDiagnosticUser role in the web.xml file for the DiagnosticData servlet. Consult the Installation Guide for more information and instructions.

Delayed disk contents

By default, to reduce the demand on system resources, the system first writes log output to a memory buffer that is 8 kilobytes in size. As a result, the contents on the disk log file may not yet contain output written minutes ago or even in some cases hours ago, depending on volume.
