-----------------------------------

             Summary: Parameterise where solr creates its console and gc log 
files
                 Key: SOLR-9971
                 URL: https://issues.apache.org/jira/browse/SOLR-9971
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: scripts and tools
    Affects Versions: 6.3
            Reporter: Jinesh Choksi
            Priority: Minor


In the $SOLR_INSTALL_DIR/bin/solr script, the location where the solr_gc.log + 
$SOLR_PORT-console.log file are created is hard wired to be inside the 
$SOLR_LOGS_DIR folder due to the following lines of code:

* {code}
GC_LOG_OPTS+=("$gc_log_flag:$SOLR_LOGS_DIR/solr_gc.log" 
-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=9 -XX:GCLogFileSize=20M)
{code}

* {code}
nohup "$JAVA" "${SOLR_START_OPTS[@]}" $SOLR_ADDL_ARGS -Dsolr.log.muteconsole \
        "-XX:OnOutOfMemoryError=$SOLR_TIP/bin/oom_solr.sh $SOLR_PORT 
$SOLR_LOGS_DIR" \
        -jar start.jar "${SOLR_JETTY_CONFIG[@]}" \
        1>"$SOLR_LOGS_DIR/solr-$SOLR_PORT-console.log" 2>&1 & echo $! > 
"$SOLR_PID_DIR/solr-$SOLR_PORT.pid"
{code}

Would it be possible to arrange for another two ENVIRONMENT variables to be 
made available which allow us to control where these two files are created?

e.g. SOLR_GC_LOG + SOLR_CONSOLE_LOG

The use case behind this request is that it is useful to keep gc and console 
logs separate from the application logs because there are different archival / 
ingestion / processing requirements for each.
