We updated our codebase recently from log4j2 v2.0-rc1 to v2.1. We use a
SocketServer. Once we did upgraded, we are not seeing exception stack
traces on lines where we used to. For example:
try {
throw new RuntimeException("Do you now to log my stackTrace?
stringstringstringE");
} catch (Exception e) {
LOGGER.error("Do you now to log my stackTrace? a:{} b:{} c:{} Yes,
I do!", "3443","4444","55555",e);
}
Does not give the stack trace. Running locally with a test log4j2 config
just writing to a file will give the stack trace.
Any ideas what changed?
We do use slf4j v.1.7.10 but that doesn't seem to be a factor because it
works locally with a test log4j2 config and also with the old SocketServer
and log4j2 v2.0-rc1.
We use a SocketServer so we also had to upgrade to TcpSocketServer.
Perhaps something has changed?
We start our socket server like:
> /usr/bin/java
> -DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector
> -DgrepToken=org.apache.logging.log4j.core.net.server.TcpSocketServer
> -server -Xms64M -Xmx256M -XX:+UseG1GC -XX:MaxGCPauseMillis=200
> -XX:GCPauseIntervalMillis=400 -Djava.net.preferIPv4Stack=true -cp
> /opt/twc/ecp:/opt/twc/ecp/lib/*
> org.apache.logging.log4j.core.net.server.TcpSocketServer 6000
> /opt/twc/ecp/log4j2.server.xml
The socket server process uses log4j2 config:
> <?xml version="1.0" encoding="UTF-8"?>
