log4j2-sftp-appender

Append the log-output from log4j2.xml to sftp server

Configuration

log4j2.xml file:

Add the import to the root element:

<Configuration status="warn" packages="io.github.c_a_services.log4j2">

Add the appender:

	<Appenders>
		<DailyFileSftpAppender
			name="sftpAppender"
			filePattern="${date:HHmmssSSS}-mule.log"
			hostName="ftp.yourdnsservername.com"
			pathName="/${sys:stage.name:-nostage}/"
			userName="ftpUserName"
			publicKeyResource="secret/ftpUserName.pub"
			privateKeyResource="secret/ftpUserName"
			passPhrase="yourPassPhrase">
			<PatternLayout pattern="%d %-5p %c{1} - %m [%t]%n" />
         <DefaultRolloverStrategy max="10"/>
		</DailyFileSftpAppender>
	</Appenders>

• name: will needs to be referenced via <AppenderRef ref="sftpAppender" /> later in the file
• filepatter: suffix of the files (date will be placed in the beginning always)
• hostName: ftp hostname
• pathName: path on that host (here prefixing with system property stage.name)
• userName: userName to connect with
• publicKeyResource: resource in your classpath (can be generated via ssh-keygen -f ftpUserName -t rsa -b 4092 -N yourPassPhrase)
• privateKeyResource: resource in your classpath
• PatternLayout: Any patternlayout
• DefaultRolloverStrategy: Days to keep logfiles.

for above example the resourepath looks like: /your-mule-application/src/main/resources/secret/ftpUserName /your-mule-application/src/main/resources/secret/ftpUserName.pub
