Installation

Add it as a maven dependency:

<dependency>
    <groupId>com.stackify</groupId>
    <artifactId>stackify-log-log4j12</artifactId>
    <version>4.0.1</version>
    <scope>runtime</scope>
</dependency>

Usage

Example appender configuration (*.properties file):

log4j.appender.STACKIFY=com.stackify.log.log4j12.StackifyLogAppender
log4j.appender.STACKIFY.apiKey=YOUR_API_KEY
log4j.appender.STACKIFY.application=YOUR_APPLICATION_NAME
log4j.appender.STACKIFY.environment=YOUR_ENVIRONMENT

Example appender configuration (*.xml file):

<appender name="STACKIFY" class="com.stackify.log.log4j12.StackifyLogAppender">
    <param name="apiKey" value="YOUR_API_KEY"/>
    <param name="application" value="YOUR_APPLICATION_NAME"/>
    <param name="environment" value="YOUR_ENVIRONMENT"/>  
</appender>

Note: If you are logging from a device that has the stackify-agent installed, the environment setting is optional. We will use the environment associated to your device in Stackify.

Be sure to shutdown Log4j to flush this appender of any errors and shutdown the background thread:

org.apache.log4j.LogManager.shutdown();

Masking

The Stackify appender has built-in data masking for credit cards and social security number values.

Enable Masking:

Add <param name="maskEnabled" value="true"/> inside the <appender> ... </appender> tag.

Customize Masking:

The example below has the following customizations:

1. Credit Card value masking is disabled (<param name="maskCreditCard" value="false"/>)
2. IP Address masking is enabled (<param name="maskIP" value="true"/>).
3. Custom masking to remove vowels using a regex (<param name="maskCustom" value="[aeiou]"/> )

log4j.appender.STACKIFY=com.stackify.log.log4j12.StackifyLogAppender
log4j.appender.STACKIFY.apiKey=YOUR_API_KEY
log4j.appender.STACKIFY.application=YOUR_APPLICATION_NAME
