I found it easier to just check the number of file descriptors that Tor
is using:
#!/usr/bin/perl -w
use strict;
# Script to monitor the amount of FDs used by
# the Tor process (var/run/tor/tor.pid)
if ($ARGV[0] and $ARGV[0] =~ /^\s*config\s*$/i)
{
print "graph_title Open file descriptors for Tor\n";
print "graph_args --base 1000 -l 0\n";
print "graph_vlabel open FDs\n";
print "graph_category network\n";
print "count.label TorFDs\n";
exit 0;
}
open (PID, "/var/run/tor/tor.pid") or exit 1;
my $pid = <PID>;
close PID;
chomp $pid;
$pid =~ /^[0-9]+$/ or exit 1;
opendir (FDS, "/proc/$pid/fd") or exit 1;
my @fds = readdir(FDS);
closedir FDS;
my $count = scalar @fds - 2;
print "count.value $count\n";

Instead of doing SETEVENTS bw and only getting a snapshow of the traffic
I gave tor its own IP address and use the ip_ plugin now, which uses
netfilter. This is probably the better option if available to you.
