![]() Navigate to the log4j2.xml file, which is located in the server/pentaho-server/tomcat/webapps/pentaho/WEB-INF/classes directory.Īdd or uncomment the following log4j appender anywhere inside the node and modify the appender's ConversionPattern to add or remove the MDC tracking properties you want to use. The log4j Mapped Diagnostic Context (MDC) tracking-related properties you want to use in the Tracking access to sensitive data usingįollow these steps to enable and configure.To meet your needs, you can configure the file size, date, time, and file compression for session_data_access.log in the log4j2.xml file. Once you configure your selected properties, Pentaho generate a daily rolling log file with the name that includes the SQL, MDX, and parameter values. The local server IP (actual Pentaho BA Server behind load balancer). So each thread can access to the values of its MDC within the thread life-cycle. Every client request will be handled by a different thread. The server name access by the user (possibly a load balancer). There is a better solution to this issue in the Logback: Mapped Diagnostic Contexts (MDC) Basically, the MDC is a map which stores the context data of the current thread. The IP address of the user who ran the report. The UUID that identifies a report and instances when it ran. Typically related to the JSession cookie. These properties use log4j's Mapped Diagnostic Context (MDC) feature and allow you to customize the logging statements that the log4j2.xml file collects: You can track access to sensitive data by configuring specific properties in the Pentaho log4j2.xml file. Correlating Pentaho logs with third-party tools. ![]() Activate logging with MDC tracking properties.Mapped Diagnostic Context (MDC) tracking.Statements within a thread and related threads. Provides the method to add additional user/session contextual information to all log The tracking properties use log4j’s Mapped Diagnostic Context (MDC) feature that These tracking properties are supported within the logging functions of theįollowing Pentaho analytics and reporting The specific piece of sensitive data a user accessed and when they accessed it.The data a specific user viewed and where they viewed it.That correlate users and IP addresses to SQL, MDX and parameter values for discovering: User access to sensitive data or investigate data breaches. Because of that, our Gradle build.You can configure tracking properties to log statements across Pentaho’s reporting and analysis tools to track The slf4j-simple results in the SLF4J facade printing all log messages with INFO level or above to be printed in the System.err. For the purpose of this blog post, we will also include the slf4j-simple library, so that we can show how the SLF4J API looks in an easy way without complicating it with additional logging framework configuration. To enable SLF4J in your project you need to include the slf4j-api library and logging framework of your choice. This kind of approach allows choosing the logging framework such as Log4j 2 or Loback during compilation just by using a different library that uses the SLF4J API. For example, in a file or in an external log centralization system like Sematext Logs. The Simple Logging Facade for Java allows us to decouple the code that is used to create log events from the implementation that will be responsible for processing and storing them in a way we want. This allows for plugging different logging frameworks at deployment time without the need for code changes. The SLF4J or the Simple Logging Facade for Java is an abstraction layer for various Java logging frameworks, like Log4j 2 or Logback. ![]() We’ll talk about its benefits and how to configure and use it with the logging framework of your choice. In this article, we’ll introduce you to SLF4J, an abstraction layer allowing you to change the logging library without the need of changing the code of your Java application. That’s why it’s a good practice to use a logging API in your code – an abstraction layer that hides the implementation details and allows compile time logging framework binding. ![]() As we explained in our Java logging tutorial, there are various frameworks available and there will be new ones that will enable faster, more powerful, and less resource expensive logging. Together, they shorten the time needed to find the root cause and allows for quick and efficient resolutions of problems.Ĭhoosing the right logging library for your Java application is one of the steps to enable logging. Java logs combined with JVM metrics and traces give full observability into the application behavior and are invaluable when troubleshooting. Logging is a crucial part of the observability of your Java applications.
