Log files capture ranging from to that can cause . Each log is managed by an , which determines the type of events written to the log file. The available log files vary, depending on the that are configured in the .

The following log files are commonly used on Pega Platform systems:

The log contains warnings, errors, and information messages about internal operations. This log is also called the console log or system log and is used for debugging the application.
The log contains performance-related alerts triggered when an operation exceeds the specified performance threshold.
The log contains alerts (identified by the prefix SECU) that suggest improper configuration of Internet Application Composer facilities, or overt attempts to bypass system security features on the Pega Platform node through URL tampering.
The log contains entries generated by the Business Intelligence Exchange (BIX) during extract operations.
The log contains performance data saved from services.
The log contains information about the setup and run-time behavior of the cluster.

Note: Pega Platform manages logs based on . For example, to log performance data for services, you add configuration file for the node.

You access log files from the in Dev Studio. The Log utilities section includes a list of log file . Clicking Log files displays a list of the log file appenders that are . Downloading a log file requires for the application server that hosts Pega Platform. You can also view log files using an external log viewer, such as .

A system administrator can in to control which logging events are displayed in the PEGA log by creating a . Events are recorded only for the .

When debugging an activity, you can use the with the logging level set to to add an event to the PEGA log regardless of settings in the . To reduce log entries and improve performance in production systems, remove InfoForced steps or convert them to comments when you finish debugging the activity.

Pega gathers the following data for PDC:
: Identifies the type of alert and the metadata captured in an interaction.
: Describes the parameters from the current parameter page, including important contextual information about the functions that run in the monitored application. All remaining parameters are filtered out and excluded.
: Details the database query, excluding business data values.
: Contains some contextual data that is a subset of the fields sent for alerts.
: Includes statistics for average response time and unique user count. PDC uses these statistics to identify overall performance and performance trends for monitored applications.
: Includes database index information. PDC uses database index information to generate recommendations to improve query performance.
