RollingFileAppender that zips?

Hi,

is there a rolling file appender that zips the rolled over file? We have
quite big log files. We would like to keep 10 times 10 mb of log files (in
xml format), resulting in 100 Mb of space waisted on people's harddisks. If
the rolled over files would be zipped, then this would dramatically be
smaller. Is this supported by log4j?

regards,

Wim

Re: RollingFileAppender that zips?

Yes you can zip files when they are rolled over. Put a '.gz' extension in the FileNamePattern.

Re: RollingFileAppender that zips?

Thanks for the info. I could not find this in the documentation.

Re: RollingFileAppender that zips?

Documentation seems to be here:
http://logging.apache.org/log4j/docs/api-1.3/org/apache/log4j/rolling/TimeBasedRollingPolicy.html

But it seems you need to use a time-based rolling policy. Is it possible to
use this with the normal RollingFileAppender? Also, it seems that this is
only added in 1.3, so we will not be able to use it yet (any ideas on
release date?).

regards,

Wim

Re: RollingFileAppender Not rolling over

Does it work if you use the standard layout class?

JDBCAppender: it doesn't reconnect, does it?

Hi.

If I have and JDBCAppender configured to throw log messages to MySQL
and, while my system is up I restart the database it does not try to
reconnect to it, does it? So i end up with my logging system
"paralized"...

Regards

AW: Logging objects

you can log anything with log4j :-]

depending on what you want to do you can use one of the following
json:
http://www.json.org
or xstream:
http://xstream.codehaus.org/index.html

and either change your log requests:
log.debug( xstream.toXML(someObject));
or
write your own Layout

regards
patrick

RE: Logging objects

In log4j 1.3 there is a ReflectionFilter that will use an object's 'toString' method as the message.  It then
creates logging event properties out of any of your object's JavaBeans-style properties before the
logging event is passed on to appenders.

It may be possible for you to backport it.

You could also write your own renderer instead - if you're looking to serialize only a single class or a few
classes.
