for!

Events in log4j can be generated in two ways:
- log methods in code (logger.debug, etc)
- a receiver
Appenders can process events generated by either of
these mechanisms.
In your case, you want to process events stored in a log
file (LogFilePatternReceiver) and store those events in a
database (JDBCAppender).
Specify both the receiver and appender configuration in
the same xml config file and it should work fine.
All you should need to do is create a simple class whose
main method calls
DomConfigurator.configure("c:/log4j/log4j.xml").
Here's an example configuration that provides a
logfilepatternreceiver and a consoleappender with an
attached expressionfilter (requires log4j 1.3 alpha jars
and jakarta-oro jar).
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration >
<log4j:configuration
xmlns:log4j="http://jakarta.apache.org/log4j/";
debug="true">
<appender name="CONSOLE"
class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.SimpleLayout"/>
<filter
class="org.apache.log4j.filter.ExpressionFilter">
<param name="Expression" value="msg ~= 'SPECIFY
CASE-INSENSITIVE MSG MATCH HERE'" />
<param name="AcceptOnMatch" value="true"/>
</filter>
<filter
class="org.apache.log4j.filter.DenyAllFilter"/>
</appender>
<plugin name="LOGFILE"
class="org.apache.log4j.varia.LogFilePatternReceiver">
<param name="fileURL" value="file:///c:/some.log"/>
<param name="timestampFormat" value="yyyy-MM-dd
HH:mm:ss,SSS"/>
<param name="logFormat" value="TIMESTAMP LEVEL
[LOGGER] MESSAGE"/>
<param name="name" value="my log file"/>
<param name="tailing" value="true"/>
</plugin>
<root>
<level value="DEBUG"/>
<appender-ref ref="CONSOLE"/>
</root>
</log4j:configuration>
ExpressionFilter supports all fields on logging events
and provides a number of operators. See the tutorial in
Chainsaw V2 for a better explanation of the syntax used
by ExpressionFilter (used in Chainsaw to
colorize/filter/search events):
http://logging.apache.org/log4j/docs/chainsaw.html
NOTE: The denyallfilter ensures events are dropped if
they weren't accepted by the expressionfilter.
Something appears to be wrong with
logfilepatternreceiver in the alpha8 distribution - if
you have the alpha7 jars, use them instead for now.

There is no way i can change config files for the
application.
I've written the program to parse log file using
logfilepatternreciever
but how can I get the log records from it?
Where are they stored during parsing?
Thanks in advance.

If not, yes, you can specify both a
logfilepatternreceive and a database appender in the
same config file.

Subject: Help with LogFilePatternReceiver
Hello,
Could someone help me please?
I need to parse log files with my program and insert
filtered rows to the Database. I don't have access to
the
program that writes this logs but it is using log4j and
i
know the format. Is it possible to use
LogFilePatternReceiver to read information from this log
file?
Could someone provide example on how to get events data?
Thanks in advance.

Alexey Vorobiev
