.IX Title "RTPSTATS 1"
.TH RTPSTATS 1 "2008-01-13" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
rtpstats.pl \- Displays packet statistics for an RTP session
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
rtpstats.pl <address> [<port>]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
rtpstats.pl displays packet statistics for an \s-1RTP\s0 session. It is a 
clone of rtpqual by Matthew B Mathis with a few changes in design. 
If no port is specified, then port 5004 is assumed.
.PP
rtpstats.pl uses seperate threads for 
recieving packets and displaying statistics, so version 5.8 or greater 
of perl is recommended for stable threading.
.PP
For every second that passes, a row is printed for each transmitter
to the multicast group. The first (left\-hand) second displays statistics for 
the current second, and the second (right\-hand) second displays the 
cumulative totals for transmitter.
.IP "1" 4
.IX Item "1"
The time in hours:minutes:seconds on the local host
.IP "2" 4
.IX Item "2"
The number of packets recieved from the transmitter in the past second.
.IP "3" 4
.IX Item "3"
The number of packets lost in the past second.
.IP "4" 4
.IX Item "4"
The number of packets that arrived late (out\-of\-order) in the past second.
.IP "5" 4
.IX Item "5"
The number of bytes (including estimated \s-1IP\s0 header size) in the past second.
.IP "6" 4
.IX Item "6"
The total number of packets recieved from the transmitter.
.IP "7" 4
.IX Item "7"
The total number of packets lost.
.IP "8" 4
.IX Item "8"
The total number of packets late (out\-of\-order).
.IP "9" 4
.IX Item "9"
The total number of kilobytes recieved from the transmitter.
.IP "10" 4
.IX Item "10"
The average kilobits per second since the first packet was recieved.
.IP "11" 4
.IX Item "11"
The \s-1IP\s0 address of the transmitter.
