Resolution: Duplicate
Closing as duplicate. See the discussion in SOLR-7728
Perhaps best practice is to separate logging per instance completely using
different SOLR_LOGS_DIR setting per instance?

> In our setup, we have two solr applications running on the same box on
> different ports. We are sharing the same distribution folder However, both
> instances log garbage collection to the same file, as shown by these two
> parts from the solr bash shell script (this is from master):
> {code}
> if [ -f "$SOLR_LOGS_DIR/solr_gc.log" ]; then
> if $verbose ; then
> echo "Backing up $SOLR_LOGS_DIR/solr_gc.log"
> fi
> mv "$SOLR_LOGS_DIR/solr_gc.log" "$SOLR_LOGS_DIR/solr_gc_log_$(date
> +"%Y%m%d_%H%M")"
> fi
> {code}
> {code}
> # if verbose gc logging enabled, setup the location of the log file
> if [ "$GC_LOG_OPTS" != "" ]; then
> gc_log_flag="-Xloggc"
> if [ "$JAVA_VENDOR" == "IBM J9" ]; then
> gc_log_flag="-Xverbosegclog"
> fi
> GC_LOG_OPTS=($GC_LOG_OPTS "$gc_log_flag:$SOLR_LOGS_DIR/solr_gc.log")
> else
> GC_LOG_OPTS=()
> fi
> {code}
> I'm proposing appending the $SOLR_PORT value into the log file name (perhaps
> only if non-default) so we can have both logs in our case. I'm happy to
> provide a patch assuming this direction is desired.
