Hey, I think I could figure it out. Using the square brackets in the value of pattern does the job. I am configuring the Syslog appender as: <appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender"> <SyslogHost>192.168.15.184</SyslogHost> <Facility>LOCAL1</Facility> <SuffixPattern>[webAppName] %msg %logger </SuffixPattern> </appender> Thanks, Pradnya On Wed, Nov 17, 2010 at 4:52 PM, Pradnya Gawade <pradnya.gawade7@gmail.com>wrote:
Hi,
I am trying to see if it is possible to send the web application name in the TAG part of Syslog message? I believe even if it is possible, I might to have to change some default code (override) of logback related to how it forms the message. But I am not sure if it is possible to change the default value that goes into the TAG field of syslog message. Any inputs?
Thanks, Pradnya

Thanks. That might be useful. I am in a process of programatically handling the stack trace to log it as a single message. But not sure syslog protocol/server has problem with line separator character which makes it display like this:
*com.abc.main.init.InitializeMainAppJob.execute(InitializeMainAppJob.java:405)#015#012#011at org.quartz.core.JobRunShell.run(JobRunShell.java:202)#015#012#011at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:525)#015#012 com.abc.main.init.InitializeMainAppJ*
any ideas?
Thanks, Pradnya

Hi,
I have following requirements when sending the log from a java web application to syslog server:
1. When logging the stack trace in case of exceptions, all the stack
strace should be seen as a single message.
Logback does not support this feature. Please create a jira issue asking for it.
Perhaps something like the indicated at "Useful Views<http://www.javaspecialists.eu/archive/Issue177.html>" may help you but using a http://logback.qos.ch/manual/layouts.html#customConversionSpecifierinstead of a Log4J Layout. HTH
2. Need to send either or all of the following information in logs-
name of the web application, URL, version of the application.
Via MDC =======
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 %msg</SuffixPattern> </appender>
By system properties ====================
Set the following system properties:
-DappName=... -DappURL=... -DappVersion
In logback.xml:
<appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender"> <SuffixPattern>%property{appName} %property{appURL} %property{appVersion} %logger %msg</SuffixPattern> </appender>
HTH
As per my knowledge, Syslog appender of Logback doesnot fit to above
requirements. I am also looking for any other logging APIs which can satisfy these requirements. Any ideas? Thanks in advance.
