Pega log

C-2383 DORID Each node on a PRPC system produces various logs, including these two:

The Pega Log — also known as the console log or system log — contains messages created since the server was most recently started. The log file is usually named PegaRULES-YYYY-MMM-DD.log, where the date portion of the name indicates the date the application server was recently started (on the current node).
The Alert log contains only alerts and supports performance-related monitoring.

Viewing or downloading the Pega log

Select> System > Tools > Logs > Log Files BYRNB 2/25/10 to view or download the current Pega log from the server to your workstation. BUG-2457 date

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. SR-7761

Log messages

In an activity, use the Log-Message method to add a message to the Pega log.

Summarizing Pega logs

A standalone Web application, the PegaRULES Log Analyzer (PLA) can summarize console logs. See PDN articles Understanding the PegaRULES Log Analyzer and How to use the PegaRULES Log Analyzer.

Rolling the log

The prlogging.xml file contains settings that can cause the system to create a new Pega log daily or on a periodic basis, rather than only at startup. Consult the Administration and Security 5.3 publication for instructions. SR-1102 SR-7252 SR-7291 SR-1140

Renaming the log

If two or more PRPC servers are installed in a single application server instance, they write lines to a common Pega log file. If this is not desirable, you can change the name or path of the Pega log for a node by modifying the prlogging.xml file. In this example the log file name starts with PEGABLUE: SR-3264
