Description

it would appear that for some reason setting an env variable of CASSANDRA_LOG_DIR is only being picked up in cassandra-env.ps1 & cassandra-env.sh and being passed to java for the gc.log*  files.

cassandra-env.ps1:    line 288:     $env:CASSANDRA_PARAMS = $env:CASSANDRA_PARAMS + " -Dcassandra.logdir=""$logdir"" -Dcassandra.storagedir=""$storagedir"""

 

However in logback.xml  the same environment variable CASSANDRA_LOG_DIR is not being picked up and passed to  (${cassandra.logdir})  

while gc.log gets redirected correctly to CASSANDRA_LOG_DIR from the java argument -Xloggc:

 

the system.log and debug.log defined in logback.xml still points to $CASSANDRA_HOME/log.

The only way I can get the debug.log and system.log log files to redirect to $CASSANDRA_LOG_DIR

is to edit the logback.xml and change the following lines manually;

 

<!-- <file>${cassandra.logdir}/system.log</file> -->
<file>/var/log/cassandra/system.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<!-- <fileNamePattern>${cassandra.logdir}/system.log.%i.zip</fileNamePattern> -->

 <fileNamePattern>/var/log/cassandra/system.log.%i.zip</fileNamePattern>

 

........

<!-- <file>${cassandra.logdir}/debug.log</file> -->
<file>/var/log/cassandra/debug.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<!-- <fileNamePattern>${cassandra.logdir}/debug.log.%i.zip</fileNamePattern> -->
<fileNamePattern>/var/log/cassandra/debug.log.%i.zip</fileNamePattern>

>> I don't know why the environment variable CASSANDRA_LOG_DIR is being picked up by  cassandra-env.ps1 & cassandra-env.sh

but not logback.xml

 

Indeed the only way I could even get cassandra-env.sh to pick up CASSANDRA_LOG_DIR environment variable was to make the following change to cassandra-env.sh;

old: JVM_OPTS="$JVM_OPTS -Xloggc:${CASSANDRA_HOME}/logs/gc.log"

new: if [ "x$CASSANDRA_LOG_DIR" = "x" ]; then

JVM_OPTS="$JVM_OPTS -Xloggc:${CASSANDRA_HOME}/logs/gc.log"
else
JVM_OPTS="$JVM_OPTS -Xloggc:${CASSANDRA_LOG_DIR}/gc.log"
