How to enable DEBUG Logging In CloudHub

cloudHub ignores the local log4j.xml configuration and even if we enable DEBUG logging in the xml file , and deploy it in cloudhub , we see no changes .

To enable logging in cloud hub , we can add following configurations in out log4j .xml

<Log4J2CloudhubLogAppender name="CLOUDHUB"
                                   addressProvider="com.mulesoft.ch.logging.DefaultAggregatorAddressProvider"
                                   applicationContext="com.mulesoft.ch.logging.DefaultApplicationContext"
                                   appendRetryIntervalMs="${sys:logging.appendRetryInterval}"
                                   appendMaxAttempts="${sys:logging.appendMaxAttempts}"
                                   batchSendIntervalMs="${sys:logging.batchSendInterval}"
                                   batchMaxRecords="${sys:logging.batchMaxRecords}"
                                   memBufferMaxSize="${sys:logging.memBufferMaxSize}"
                                   journalMaxWriteBatchSize="${sys:logging.journalMaxBatchSize}"
                                   journalMaxFileSize="${sys:logging.journalMaxFileSize}"
                                   clientMaxPacketSize="${sys:logging.clientMaxPacketSize}"
                                   clientConnectTimeoutMs="${sys:logging.clientConnectTimeout}"
                                   clientSocketTimeoutMs="${sys:logging.clientSocketTimeout}"
                                   serverAddressPollIntervalMs="${sys:logging.serverAddressPollInterval}"
                                   serverHeartbeatSendIntervalMs="${sys:logging.serverHeartbeatSendIntervalMs}"
                                   statisticsPrintIntervalMs="${sys:logging.statisticsPrintIntervalMs}">

            <PatternLayout pattern="[%d{MM-dd HH:mm:ss}] %-5p %c{1} [%t] CUSTOM: %m%n"/>
        </Log4J2CloudhubLogAppender>

And add this appender along with your file appender .

<AppenderRef ref="CLOUDHUB"/>

Now you can deploy it on cloud hub and it should work fine .
You can also change Additional log levels and categories to include in logs in cloud hub .
Just click on Manage Application -> Settings -> Logging

There you can see logging levels , select desired logging level from drop down and write your package name , like com.mulesoft . And then click on apply changes . And those changes will be affected in your cloudhub logs
