C-2383 DORID Each node on a Process Commander system produces two logs:

• 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 FilesBYRNB 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 PRKB-25406 Understanding the PegaRULES Log Analyzer and PRKB-25392 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 Process Commander 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

<param name="FileNamePattern"
      value="C:\LOGS\PEGABLUE-'yyyy-MMM-dd'.log" />
