Works well after minor change

As stated in the dev guidelines (https://nagios-plugins.org/doc/guidelines.html#AEN200) I had to change the following line to include spaces between each performance data otherwise it would only graph the first entry (CPU).

PERFORMANCE=”cpu=$CPU_PC; comp_cpu=$COMPRESSION_CPU_PC; wcache=$WRITE_CACHE_PC; tcache=$TOTAL_CACHE_PC; latency=$BIGGEST_LATENCY”
146 PERFORMANCE=”$PERFORMANCE; fc_mb=$FC_MB; fc_io=$FC_IO; sas_mb=$SAS_MB; sas_io=$SAS_IO; iscsi_mb=$ISCSI_MB; iscsi_io=$ISCSI_IO”
