Target[server-1.location-5.Swap]: memTotalSwap.0&memTotalSwap.0:public@192.168.5.129:161::::2 - memAvailSwap.0&memAvailSwap.0:public@192.168.5.129:161::::2

in two (in vi):

%s: `/usr/local/bin/snmp_mem_usage.pl public ::g
%s/:\(.\+\) real`/ memTotalReal.0\&memTotalReal.0:public@\1:161::::2 - memAvailReal.0\&memAvailReal.0:public@\1:161::::2/
