perl Sys::Syslog logs fqdn

John Kittel — Mon, 26 Mar 2007 12:06:40 GMT

All previous existing entries in my syslog.log have the format:

MMM DD HH:MM:SS LF:name tag: message

where LF are level and facility ( I use -v in syslog options), and name = simple host name.

And, if I use logger to log a message, I get the same format.

BUT, if I use a perl program, the simple host name becomes a fully qualified host.domain-name.

Is there a way to use the perl module Sys::Syslog to log messages with only the simple host name, not the fully qualified name?
(I'm looking, and trying various things, but don't see a way. I guess I could use system or backticks to call logger...)

Thanks.

Oh, I'm using Sys::Syslog (version 0.01). I see there are newer versions available. I haven't checked if newer versions address this...

I've never used this module but one thing jumps out at me. When you invoke openlog what are you using as $ident? ... and did you, in fact, call openlog before using the syslog function?

Hi:

I don't think that you can control the logging (but then why?). WHen you extract your log, simply snip/substitute off the domain name.

# echo "server.in.domain"|perl -nle 'print $1 if /(.+?)(\..+)/'

Thanks, guys.

Clay, I tried using openlog, and without using openlog. Using openlog, with $ident = simple hostname, I get the same format

MMM DD HH:MM:SS LF:name tag: message

where name = fully qualified name, and tag = the simple host name that I put in $ident.

JRF, the syslog is forwarded to another system managed by someone else, who is creating reports from it. I was just in the initial stages of developing this, and thought it would be simpler for them if the messages all had the same format.
