Thanks.
Then, you might want to replace the above with something like this:

  # Sample input:
  # $ host -N 3 -t srv _ipp._tcp
  # _ipp._tcp.rdu.redhat.com has SRV record 10 0 631 cups.rdu.redhat.com.
  server_port=$(host -N 3 -t srv _ipp._tcp \
                | sed 's/.* \([0-9][0-9]*\) \([^ ][^ ]*\)\.$/\2 \1/')

  case $server_port in
      *' '*)
          printf "found! Using server:port '$DEFAULT_SERVER:$DEFAULT_PORT'.\n"
          eval ovirt_rsyslog $server_port udp
          ;;
      *)
          printf "not found!\n"
          ;;
  esac
