I am trying to graph the number of GPS satellites my receiver is seeing, however, what is returned via SNMP has more information than what I need.  

This is from the documentation.  I just want to strip the first integer as the answer. 

For one satellite with vehicle number 16:
1,16,C,-158       <-- I need the "1"
For six satellites:
6,12,C,-156,14,C,-155,8,T,-162,24,C,-158,18,C,161,6,C,-160   <-- I need the "6"

Can Observium do this?


Thanks,
