Hi,

I'm trying to transfer wso2carbon logs to elk using tcp input plugin

my config for wso2 log4jproperties file.

#TCP logger pattern  
log4j.appender.tcp=org.apache.log4j.net.SocketAppender  
log4j.appender.tcp.layout=org.wso2.carbon.utils.logging.TenantAwarePatternLayout

# ConversionPattern will be overridden by the configuration setting in the DB

log4j.appender.tcp.layout.ConversionPattern=TID: [%T] [%S] [%d] %P%5p {%c} - %x %m {%c}%n  
log4j.appender.tcp.layout.TenantPattern=%U%@%D [%T] [%S]  
log4j.appender.tcp.Port=6000  
log4j.appender.tcp.RemoteHost=localhost  
log4j.appender.tcp.ReconnectionDelay=10000  
log4j.appender.tcp.threshold=DEBUG  
log4j.appender.tcp.Application=wso2carbon

Config for logstash.conf

input {  
tcp {  
mode =\> server  
port =\> 6000  
add\_field =\>  
type =\> "wso2carbon"  
}  
}  
}

I'm successfully getting messages from wso2carbon. but the message like encrypted format. like below.

{  
"message" =\> "threadNameq\u0000~\u0000\u0001L\u0000\rthrowableInfot\u0000+Lorg/apache/log4j/spi/ThrowableInformation;xp\u0000\u0000\u0000\u0000\u0001c\xD9\xC9\xF3,t\u0000Forg.wso2.carbon.databridge.agent.endpoint.DataEndpointConnectionWorkerpsr\u0000\u0013java.util.Hashtable\u0013\xBB\u000F%!J\xE4\xB8\u0003\u0000\u0002F\u0000",  
"host" =\> "127.0.0.1",  
"@version" =\> "1",  
"port" =\> 59581,  
"type" =\> "wso2carbon",  
"@timestamp" =\> 2018-06-07T10:28:01.179Z,  
"tags" =\> [  
[0] "\_grokparsefailure"  
]  
}

please let me know how to decrypt this.

You could replace the tcp input with a [log4j](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-log4j.html) input, but you should read and understand why the log4j input is deprecated.

HI Badger, Thanks for ur quick response.

i tried with that also. but i am not getting any messages from wso2 carbon.

> log4j {  
> mode =\> server  
> port =\> 6000  
> add\_field =\> {  
> type =\> "wso2carbon"  
> }  
> }

This is my wso2 log4j configuration.
