I have a simple Maven configuration where I know the following is on the classpath (I can verify it at runtime before Spring Boot starts up in my application class): com.splunk.logging:splunk-library-javalogging:1.6.2 The Maven dependency looks like: <dependency>
<groupId>com.splunk.logging</groupId>
<artifactId>splunk-library-javalogging</artifactId>
<version>1.6.2</version>
</dependency> I made sure that Spring Boot is loaded this way: <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>${version.spring.boot}</version>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j2</artifactId>
<version>2.5.4</version>
</dependency>
I created an appender this way: <?xml version="1.0" encoding="UTF-8"?>
<Configuration status="info" name="LoggingTesting" packages="">
<Appenders>
<SplunkHttp name="SPLUNK_APPENDER_1"
url="http://SPLUNK_IP:8088/services/collector/event"
token="MY_TOKEN"
source="SampleJavaAppender1"
messageFormat="text"
batch_size_bytes="0"
batch_size_count="5"
batch_interval="0"
connect_timeout="5000"
disableCertificateValidation="true">
<PatternLayout pattern="%m"/>
</SplunkHttp> When I launch my application, I get this error: main ERROR Error processing element SplunkHttp ([Appenders: null]): CLASS_NOT_FOUND main ERROR Unable to locate appender "SPLUNK_APPENDER_1" for logger config "root" This was all based on the sample Log4J2 configuration . What am I missing in my configuration?
