Hi Piotr,
One more thing I've seen. Finally, I'm modifying directly in the log4j2.xml
file the buffer size of one of my loggers. I have enabled the debug, the log4j2
xml file has a monitor interval of 30 seconds.
I start my application with a buffer of 8K. Then:
1. I programmatically change it to 16K while the app is running:
INFO: 2025-01-28T17:56:17.015816443Z main TRACE Configured node
RollingRandomAccessFile Key[type: int; name: bufferSize; qualifierType:
PluginBuilderAttribute]=16384
I check the log4j2.xml file:
<RollingRandomAccessFile name="ACCESS_LOG"
fileName="${sys:log.dir}vproxy_access"
filePattern="${sys:log.dir}vproxy_access.%d{yyyy-MM-dd}" append="true"
bufferedIo="true" bufferSize="16384" immediateFlush="false">
2. Then I change it to 2K:
INFO: 2025-01-28T17:57:47.216638176Z
Log4j2-TF-1-ConfigurationFileWatcher-6 TRACE Configured node
RollingRandomAccessFile Key[type: int; name: bufferSize; qualifierType:
PluginBuilderAttribute]=2048
Check:
<RollingRandomAccessFile name="ACCESS_LOG"
fileName="${sys:log.dir}vproxy_access"
filePattern="${sys:log.dir}vproxy_access.%d{yyyy-MM-dd}" append="true"
bufferedIo="true" bufferSize="2048" immediateFlush="false">
The point is that, while I'm logging, the ratio of lines that are logged is
always the same, with 2048 it should be continually logging and with 16384 I
should see pauses between two consecutive loggings. But not.
Then, if I restart the application, it works as expected.
So, is it possible that changing the buffer size for this
'RollingRandomAccessFile' is not working on runtime?
Thanks,
Joan.
