Hazelcast Server Setup for Log4j or custom Logging? (Server Side logging)

[Benjamin E.Ndugga]

 I have copied the log4j-1.2.17.jar in the lib/ folder and have added it to the classpath as shown in the start.sh script and i have added the property for the logging type to log4j with the Configuration file all shown below. However all has failed to work.

Can someone see where the problem is?

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true"  xmlns:log4j='http://jakarta.apache.org/log4j/'>
   <appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">
      <layout class="org.apache.log4j.PatternLayout">
         <param name="ConversionPattern" value="%d{dd MMM yyyy HH:mm:ss} %5p %c{1} - %m%n"/>
      </layout>
   </appender>
   <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
      <param name="append" value="false"/>
      <param name="file" value="/opt/hz-file.log"/>
      <layout class="org.apache.log4j.PatternLayout">
         <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/>
      </layout>
   </appender>
   <root>
      <level value="DEBUG"/>
      <appender-ref ref="consoleAppender"/>
      <appender-ref ref="fileAppender"/>
   </root>
</log4j:configuration>

 <property name="hazelcast.logging.type">Log4j</property>

#### maximum heap size
MAX_HEAP_SIZE=1G

if [ "x$MIN_HEAP_SIZE" != "x" ]; then
        JAVA_OPTS="$JAVA_OPTS -Xms${MIN_HEAP_SIZE}"
fi

if [ "x$MAX_HEAP_SIZE" != "x" ]; then
        JAVA_OPTS="$JAVA_OPTS -Xmx${MAX_HEAP_SIZE}"

echo "# starting now...."
echo "########################################"

PID=$(cat "${PID_FILE}");
if [ -z "${PID}" ]; then
    echo "Process id for hazelcast instance is written to location: {$PID_FILE}"
        $RUN_JAVA -server -cp "../lib/*"  $JAVA_OPTS com.hazelcast.core.server.StartServer &
    echo $! > ${PID_FILE}
else
    echo "Another hazelcast instance is already started in this folder. To start a new instance, please unzip 3.6.zip/tar.gz in a new folder."
    exit 0

Hi Benjamin,

can you try to use 

 <property name="hazelcast.logging.type">log4j</property>

=with the lower-case initial l ?

Cheers,

Jaromir

Hi Jaromir,

Thank you soo much, the server can now read the the property change, but here is how it gets interesting from the output that I get, it seems my log4j.xml file can not be seen even after adding it to the JAVA_OPTS

[benjamin@oc6807683863 bin]$ ./start.sh

I am not a log4j expert, but you can try something like this:

-Dlog4j.configuration=file:"/absolute/path/log4j.xml"

If this is working then you can experiment with relative path to make it more portable.

Cheers,

 Hi Jaromir,

I have managed to make it work, thank u soo much

soo here is the new configuration line:

JAVA_OPTS="$JAVA_OPTS -Dlog4j.configuration=file:///home/benjamin/APIs/Hazelcast/hazelcast-3.6/bin/log4j.xml"

It as worked !!!!!!!!!!!!!!!
