Logback does not support this feature. Please create a jira issue asking 
for it.

Add the following code when your web-app starts:

MDC.put("appName", ...);
MDC.put("appURL", ...);
MDC.put("appVersion", ...);

In logback.xml:

<appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
    <SuffixPattern>%mdc{appName} %mdc{appURL} %mdc{appVersion} %logger

By system properties

Set the following system properties:

-DappName=... -DappURL=... -DappVersion

In logback.xml:

<appender name="SYSLOG"
    <SuffixPattern>%property{appName} %property{appURL}
%property{appVersion} %logger  %msg</SuffixPattern>
