Hi all. I didn't want to bump any of the existing threads for this, so I hope that it's ok if I create a new thread.
For reference, I've followed all of the instructions in these threads to get graphing with mrtg and icecast working:
http://icecast.imux.net/viewtopic.php?t=337
http://icecast.imux.net/viewtopic.php?t=6439
We are a small community radio station streaming on the internet, and after looking around, this seems to be the best solution for getting some listener graphs for the station. However, I'm having a hell of a time getting this working properly and have completely run out of ideas.
Our streaming server runs multiple streams for other various stations. I'm trying to only gather data from our mountpoint/stream and display that data. I don't know if the scripts are grabbing data for all of the streams, but the number that's being displayed is incredibly inaccurate (sample below). The number displayed doesn't even represent the amount of listeners across all streams combined.
I'm coming to you guys for help on this one. I have no idea what else I'm missing, but it's probably very simple.
Here is the script that I'm using:
| Code: |
#!/usr/bin/perl
use strict;
#get the number of listeners on a icecast stream
#(find out total bytes later)
my $staturl = qq~http://[my server]:[streaming port]/admin/stats~;
my $user = '[admin username]';
my $pass = '[admin pass]';
#my $stream = "[name of the mount point/stream]";
my $uptime = '0 days';
my $listeners = 0;
my $sources = 0;
#get listeners
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
my $req = HTTP::Request->new(GET => $staturl);
$req->authorization_basic($user, $pass);
my $stats = $ua->request($req)->as_string;
while ($stats =~ /<listeners>(\d+)<\/listeners><listenurl>/g) {
$listeners += int($1);
}
$stats =~ /<sources>(\d+)<\/sources>/;
$sources = $1;
if (!$listeners) {$listeners = 0;}
if (!$sources) {$sources = 0;}
#get uptime
# use Date::Manip;
# my $stuff = `ps --no-headers -C icecast -o pid,fname,lstart --sort lstart`;
# my @stuff = split(/\n/,$stuff);
# $stuff[0] =~ /icecast\s+(.*?)$/gi;
# my $start = ParseDate($1);
# my $now = ParseDate("Now");
# my $delta = DateCalc($start,$now);
# $uptime = Delta_Format($delta,0,"%dh days %hv hours");
# print qq~$listeners\n$sources\n$stream\n~;
print qq~$listeners\n$sources\n$uptime\n~;
# $stream\n~;
exit;
|
I commented out all of the uptime stuff because I don't really need it, and the stats gathering and displaying is happening on a different machine that icecast isn't running on.
Here is my mrtg.cfg

I have a cron job running every 5 minutes to gather, display and update the data:
| Code: |
0,5,10,15,20,25,30,35,40,46,50,55 * * * * env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg >/dev/null 2>&1 |
At 18:53 (-7h GMT) I took stats, and snapped this pic of the graph (click to enlarge):
At that exact moment, there were a combined total of 78 active connections to our streaming server, and only 4 connections to the stream that I'm trying to pull stats for.
I've blanked out some of the sensitive info because of my own paranoia. But can assure you that the data in the brackets [] is correct.
Thank you for your help. |

| Does this perl script if you run it from the command prompt give you an adequate result (e.g. first line - listeners count, second line - sources count? |

It doesn't. I ran it just now and it returned:
At that moment there were 129 listeners across the entire server, and 12 sources. But on the stream I need data for, there were only 5 listeners. |
