I'm starting to get a little worried about the N awk processes we're creating every second. Won't scale as N gets larger but fine until proven otherwise I guess

netsnmp()
{
  # $1: section name, e.g. "udp"                                                                                                                                                                                                                                                   
  # $2-....: field names to query, e.g. "udp"
