I'm using filebeat to collect logs from a java service into ELK stack. As we all know the java stacktrace are multilines so i config the filebeat stated here：
multiline:
pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}.*'
negate: true
match: after
The stacktrace are combined together successfully, however I don't know why the lines are concated by \n\t which makes the final message hard to read, like this:
org.apache.shardingsphere.driver.jdbc.core.statement.ShardingSpherePreparedStatement$2.executeSQL(ShardingSpherePreparedStatement.java:412)\n\tat org.apache.shardingsphere.driver.jdbc.core.statement.ShardingSpherePreparedStatement$2.executeSQL(ShardingSpherePreparedStatement.java:408)\n\tat org.apache.shardingsphere.infra.executor.sql.execute.engine.driver.jdbc.JDBCExecutorCallback.execute(JDBCExecutorCallback.java:85)\n\tat org.apache.shardingsphere.infra.executor.sql.execute.engine.driver.jdbc.JDBCExecutorCallback.execute(JDBCExecutorCallback.java:64)\n\tat org.apache.shardingsphere.infra.executor.kernel.ExecutorEngine.syncExecute(ExecutorEngine.java:101)\n\tat org.apache.shardingsphere.infra.executor.kernel.ExecutorEngine.parallelExecute(ExecutorEngine.java:97)\n\tat org.apache.shardingsphere.infra.executor.kernel.ExecutorEngine.execute(ExecutorEngine.java:82)\n\tat org.apache.shardingsphere.infra.executor.sql.execute.engine.driver.jdbc.JDBCExecutor.execute(JDBCExecutor.java:65)\n\tat org.apache.shardingsphere.infra.executor.sql.execute.engine.driver.jdbc.JDBCExecutor.execute(JDBCExecutor.java:49)\n\tat org.apache.shardingsphere.driver.executor.DriverJDBCExecutor.doExecute(DriverJDBCExecutor.java:153)\n\tat org.apache.shardingsphere.driver.executor.DriverJDBCExecutor.execute(DriverJDBCExecutor.java:142)\n\tat
This is the raw console output of filebeat.
I'm expecting the log texts are shown as original format(real new line, rather that \n):

Any suggestions for the problem? Thanks in advanced.
