Problem

By default number of logs generated for each node is 10 files with a size of 10 MB.
It is possible to change the number of file and size from file /Interchange/conf/log4j2.xml.

Resolution

For example, if you want to have 20 files with a size of 30 MB.

Edit file /Interchange/conf/log4j2.xml :

<Appenders>
<RollingFile name="NodeAppender"
fileName="${sys:axway.cluster.logDir}/${sys:axway.cluster.node.name}.log"
filePattern="${sys:axway.cluster.logDir}/${sys:axway.cluster.node.name}.%i.log">
<!-- use this pattern to prevent CRLF injection. It will change \n and \r characters in the message to _ -->
<PatternLayout pattern="%d{DEFAULT} - %-5level [%t]%notEmpty{[P/EP: %X{EP_PARTNER}/%X{EP_NAME}]} (%c{1}) - %replace{%msg}{[\r\n]}{_}%n"/>
<!-- use this pattern to prevent CRLF injection. It will change \n and \r characters in the message to _ and in the stack traces in to | -->
<!--<PatternLayout alwaysWriteExceptions="false" pattern="%d{DEFAULT} - %-5level [%t]%notEmpty{[P/EP: %X{EP_PARTNER}/%X{EP_NAME}]} (%c{1}) -
%replace{%msg}{[\r\n]}{_} %replace{%throwable}{[\r\n]{1,2}}{|}%n"/>-->
<!-- use this pattern to ignore CRLF injection. -->
<!--<PatternLayout pattern="%d{DEFAULT} - %-5level [%t]%notEmpty{[P/EP: %X{EP_PARTNER}/%X{EP_NAME}]} (%c{1}) - %enc{%msg}%n"/>-->
<Policies>
<SizeBasedTriggeringPolicy size="30 MB"/>
</Policies>
<DefaultRolloverStrategy max="20"/>
</RollingFile>

A restart of B2Bi is required to take the modification into account.
