Environment:

In our application, we are using log4j2 (2.8.1 version jar) framework and SocketAppender (async appender under socket appender) to send logs to Splunk ( Enterprise Logging tool) via radware(load balancer) using tcp protocol.

Description

We are facing intermittent lost of logs while sending logs to log target using log4j2 socket appender in our application. The detailed information is as below;

Our environment:
1) In our application, we are using log4j2 (2.8.1 version jar) framework and SocketAppender (async appender under socket appender) to send logs to Splunk ( Enterprise Logging tool) via radware(load balancer).
2) So our application connects to Radware over TCPIP socket using SocketAppender; Radware is used to load balance load among 4 target Splunk servers.
3) Radware Server is configured to timeout if connection is idle for one minute (configurable at radware and set to 1 minute)
4) The configuration of log4j2 config file is as below

<?xml version="1.0" encoding="UTF-8"?>
  <Configuration status="trace" monitorInterval="5">
    <Appenders>
      <Socket name="socket" host="10.52.214.26" port="1514" reconnectDelayMillis="30000" immediateFail="false" bufferedIo="true" bufferSize="204800" protocol="TCP" immediateFlush="false">
        <PatternLayout></PatternLayout>
      </Socket>
      <Async name="SplunkAsync" bufferSize="204800">
        <AppenderRef ref="socket"/>
      </Async>
    </Appenders>
    <Loggers>
      <Root level="warn">
        <AppenderRef ref="SplunkAsync"/>
      </Root>
      <Logger name="SplunkInfoLogger" level="info" additivity="false">
        <AppenderRef ref="SplunkAsync"/>
      </Logger>
      <Logger name="SplunkDebugLogger" level="debug" additivity="false">
        <AppenderRef ref="SplunkAsync"/>
      </Logger>
      <Logger name="SplunkWarnLogger" level="warn" additivity="false">
        <AppenderRef ref="SplunkAsync"/>
    </Logger>
  </Loggers>
</Configuration>

The process/steps of meeting problem:

1) Splunk servers, radware server and our application servers are up, and the application servers send logs to radware in turn splunk servers successfully.
2) As we didn't do any operation, there is no logs come into radware in one minute ( 1 minute as we set) and radware breaks the connection between it and application server.
3) We did an operation so that application server will write one log. However nothing happens, This log didn't come into radware and splunk servers at all.
4) We did a second operation so that application server will write the second log. This time also logs did not come into radware and splunk either.
5) After counting for 30 sec (reconnectDelayMillis="30000" in log4j2 config file) from first failed log ( i.e the log triggered after radware breaks connection) we did a third operation so that application server will write the third log. This time SocketAppender works well and this log came into radware and splunk servers. This is primarily because application server is able to re-establish connection to Radware after 30 sec as reconnectDelayMillis="30000"

I would like to know why initial logs are lost which are sent after radware connection becomes idle. Ideally, tcp connection created by log4j2 should keep the data in buffer when connection is broken and should send data from buffer when reconnection is established after 30 secs (reconnectDelayMillis="30000" )

We tried setting up parameters like immediateFail="false" bufferedIo="true" bufferSize="204800", so that data can be stored in buffer when radware times out tcp connection and can be sent later when reconnection to radware is established, Unfortunately which is not happening.

Are we missing any configurations because which we are facing this type of behaviour or is it known defect.

The similar kind of issue is also observed by others and raised in apache jira(https://issues.apache.org/jira/browse/LOG4J2-1311)
