--------------------------------
NM, version of perl module in CPAN is v0.2, version with trafficserver is v3.4.

> Traffic_top is working with trafficserver 5.3.1. I am trying to get
> statistics from trafficserver via the management api socket using both the
> perl module
> (http://search.cpan.org/~bvierra/Apache-TS-AdminClient-0.02/lib/Apache/TS/AdminClient.pm)
> and a ruby script equivalent.
> The perl script is:
> ---
> #!/usr/bin/perl
> use Apache::TS::AdminClient;
> my $cli = Apache::TS::AdminClient->new(socket_path =>
> "/run/trafficserver/mgmtapi.sock");
> my $string = $cli->get_stat("proxy.config.product_company");
> print "$string\n";
> ---
> And seems to work except gets no response:

> stat("/run/trafficserver/mgmtapi.sock", {st_mode=S_IFSOCK|0700, st_size=0,
> ...}) = 0
