Log4j

Log4j is used to retrieve logs from Java applications. Logs from Log4j can be sent to the Logmanager server via Syslog protocol.

1. You need to find the configuration file for Log4j in the Java application. Most often is saved as logging.properties file or log4j.properties file.

2. Edit configuration file:

   rootLogger = DEBUG, udp
   
   appender.udp = org.apache.log4j.receivers.net.UDPAppender
   appender.udp.RemoteHost = <Logmanager_IP_address>
   appender.udp.port = 514
   appender.udp.layout.type = org.apache.log4j.PatternLayout
   appender.udp.layout.ConversionPattern = java %d{yyyy-MM-dd HH:mm:ss,SSS}{GMT} %p %t %c %M - %m%n
   

   Logmanager_IP_address is IP address your Logmanager server.

3. Restart Java application to load new configuration file.

4. Now continue to configure classifiers and parser on the Logmanager server.

1. You need to find the configuration file for Log4j2 in the Java application. Most often is saved as logging.properties file or log4j2.properties file.

2. Edit configuration file:

   appender.socket.type = Socket
   appender.socket.name = socket
   appender.socket.host = <Logmanager_IP_adresa>
   appender.socket.port = 514
   appender.socket.protocol = UDP
   appender.socket.layout.type = PatternLayout
   appender.socket.layout.pattern = ${hostName} java %d{yyyy-MM-dd HH:mm:ss,SSS}{GMT} %p %t %c %M - %m%n
   
   rootLogger.level = debug
   rootLogger.appenderRef.socket.ref = socket
   

   Logmanager_IP_address is IP address your Logmanager server.

3. Restart Java application to load new configuration file.

4. Now continue to configure classifiers and parser on the Logmanager server.
