[logback-user] Hostname in SMTPAppender subject

[Mayes, Christopher]

Okay, I've gotten this working.  I should note that the hostname System property must be fed as a JVM argument (the blog post uses -Dhostname=`uname -n`).

I've noticed an odd issue with parentheses, though.  Including a closing paren (matched or not) truncates the rest of the format and pulls up the next line in the message.  So this format:

[CFG_SERVER] =${hostname}=  )  %logger{20} - %m %nopex

Gives the email subject:

[CFG_SERVER] =dv1035c=  java.io.FileNotFoundException: /tmp/cfg_server.data (Permission denied) at java.io.RandomAccessFile.open(Native Method)
<snipped remainder of stack>

Removing the closing paren:

[CFG_SERVER] =${hostname}=  %logger{20} - %m %nopex

Produces the expected output:

[CFG_SERVER] =dv1035c=  n.s.e.s.DiskStore - cfg_serverCache: Could not create disk store. Initial cause was /tmp/cfg_server.data (Permission denied)

What would cause this behavior?

Thanks,

-Chris

Hello Chris,

It should work the same way. If it doesn't, it is a bug. If so, I would
appreciate if you could file a bug report at http://jira.qos.ch/
