I'm using perl-script like this for that:
call like  <scriptname> <udmlog-file>
----
#!/usr/bin/env perl
use strict;
use warnings;
use JSON::Syck qw(LoadFile);

my $j = LoadFile( $ARGV[0] ) or die;
foreach my $msm (@$j) {
   my $traceroute = $msm->{result};
   $traceroute =~ s/NEWLINE/\n/g;
   print $traceroute;
}
---
(requires JSON::Syck installed, typically 'sudo cpan JSON::Syck' should
get that installed for you on the system you run this on).
