Hi log4j developers....
|
|
|
|
|
|
Here, for your consideration, is a set of files that
|
|
implement an Appender which sends messages
|
|
to a remote host/port via UDP (datagram).
|
|
|
|
|
|
There was brief discussion of this Appender on the
|
|
log4j-user group, about a week ago. Ceki suggested
|
|
that the Appender send serialized log event objects
|
|
over UDP; while this approach has a number of
|
|
advantages, I have decided to instead perform the
|
|
message formatting at the client end, mainly so
|
|
that:
|
|
(a) the UDP server application does not have to be in java
|
|
(b) non-java clients can send messages to the same UDP
|
|
server.
|
|
|
|
|
|
The appender has been named "DatagramStringAppender"
|
|
to allow someone to write a serialization-based version at
|
|
some later time, if desired, without any name confusion.
|
|
------------------------------
|
|
Notes:
|
|
|
|
|
|
DatagramStringAppender is based on SyslogAppender, but
|
|
with a fair number of changes.
|
|
|
|
|
|
DatagramStringWriter is based on SyslogWriter, with a few changes.
|
|
In particular, it takes an "encoding" parameter, so that the character
|
|
encoding used can be specified, and a "port".
|
|
|
|
|
|
SingleLineTracerPrintWriter is almost identical to
|
|
SyslogTracerPrintWriter; just the name & some comments
|
|
have changed. [I didn't want to call a class called SyslogXXX
|
|
from the DatagramStreamAppender classes]
|
|
------------------------------
|
|
|
|
|
|
If this patch is accepted, then it may be worth rewriting SyslogAppender
|
|
to use the DatagramStringWriter and SingleLineTracerPrintWriter
|
|
classes. These classes should be compatible with SyslogAppender,
|
|
as they implement the same functionality, or a superset of the
|
|
Syslog functionality, and have more "general" names.
|
|
------------------------------
|
|
<<DatagramStringAppender.java>>
|
|
|
|
|
|
|
|
<<DatagramStringWriter.java>>
|
|
|
|
|
|
<<SingleLineTracerPrintWriter.java>>
|
|
|
|
|
|
--------------------------------
|
|
And here's a simple perl UDP server, and an xml
|
|
config file for testing the appender.
|
|
<<logconfig.xml>>
|
|
|
|
|
|
<<udpserver.pl>>
|
|
|
|
|
|
Regards,
|
|
|
|
|
