No the data record Im writing is about 446 bytes. But dont know why the
maxsize param
does not limit the file size to 0.5 KB.
Anyways I found a workaround. I used a customised RollingFileAppender
and configured it
for "minute" rollover.
<param name="datePattern" value="'.'yyyy-MM-dd-HH-mm"/>
Since my ConnectionMonitor Thread also logs the data record every minute,
I get
exactly one record in the log file.
Thanks Philip & everyone else for their valuable inputs.

Is the data record you are writing bigger than 0.5 KB?
If so then unfortunately I don't have any other ideas for file based
logging.
Have you given any thought to perhaps storing the record in another form
such as a database record?
Or even provide the data in real - time through a UI screen in your app.
In this way you would not need to log the data at all.
Cheers,
Philip.

Thanks Philip & James for your suggestions.
Unfortunately , it still didnt work.
log4j just refuses to wipe out all traces of it's logging (-:
Below is the appender config I used.
I have used the RollingFileAppender this time, and configured it for
minutely roll over, max size = 0.5 KB and MaxBackupIndex of 0.
<appender name="connectionPoolApp"
class="org.apache.log4j.RollingFileAppender">
<param name="File" value="${log.dir}/connectionPools.log"/>
<param name="datePattern" value="'.'yyyy-MM-dd-HH-mm"/>
<param name="Append" value="false"/>
<param name="MaxBackupIndex" value="0"/>
<param name="MaxFileSize" value="0.5KB"/>
<param name="ImmediateFlush" value="true"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601}
%-5p %c %m%n"/>
</layout>
</appender>
Any suggestions are
welcome.
Thanks

I guess if you also set the max size on the file to some small number it
would roll after 1 entry.
Example:
MaxFileSize=0.1MB
This means after the file gets to 100 KB it would roll and since your
max backups is set to zero it would overwrite.
You might be better served by simply implementing your own logging for
the connection pool and avoiding these kinds of hacks.
Cheers,
Philip.

Look at the rolling file appenders. One of them has the option of
specifying the max backups. If you set the max to 0 you would probably
be close to what you want.
