<H2><A NAME="ss13.1">13.1</A> <A HREF="manual.html#toc13.1">Status Port</A>
</H2>
<P>The status port is the external interface for monitoring and controlling the gatekeeper.
The gatekeeper will send out messages about ongoing calls to all
connected clients and it can receive commands via this interface.</P>
<P>The messages sent by the gatekeeper to the status port are grouped
into three <B>output trace levels</B>:
<UL>
<LI>Level 0
<BLOCKQUOTE>
Reload notifications and direct replies to entered commands.
</BLOCKQUOTE>
</LI>
<LI>Level 1
<BLOCKQUOTE>
Reload notifications, direct replies to entered commands, CDRs and Route Requests.
</BLOCKQUOTE>
</LI>
<LI>Level 2
<BLOCKQUOTE>
Output everything (reload notifications, direct replies to entered commands,
CDRs, Route Requests, RAS, ...). This is the <B>default</B> output level.
</BLOCKQUOTE>
</LI>
</UL>
The client connected to the status port can choose the output level it is interested in.</P>
<P>The interface is a simple TCP port (default: 7000), you can connect to with telnet or another client. One example of a different client is the Java GUI, aka GkGUI.
Another example is the Automatic Call Distribution application, aka GnuGk ACD.</P>
<H3>Application Areas</H3>
<P>What you do with the powers of the Status Interface is up to you, but here are a few ideas:
<UL>
<LI>Call Monitoring</LI>
<LI>Monitoring the registered endpoints</LI>
<LI>Graphical User Interface
<BLOCKQUOTE>
See GkGUI.
</BLOCKQUOTE>
</LI>
<LI>Call Routing
<BLOCKQUOTE>
See GnuGk ACD.
</BLOCKQUOTE>
</LI>
<LI>Billing Applications
<BLOCKQUOTE>
Analyze the CDR messages and forward them to a billing application.
</BLOCKQUOTE>
</LI>
<LI>Interfacing external extensions
<BLOCKQUOTE>
If you don't want to publish the source code to additional features, just publish the core functionality and interface to it through the status interface and keep the external part private.
</BLOCKQUOTE>
</LI>
</UL>
</P>
<H3>Examples</H3>
<P>Suppose you are just interested in the CDRs (call details records) and want to process them as a batch at regular intervals.</P>
<P>Here is a simple Perl script (<CODE>gnugk_cdr.pl</CODE>) that starts the gatekeeper and also forks a very simple client for the Status Interface and writes just the CDRs into a logfile. You'll have to modify it a little to fit your needs.</P>
<P>
<PRE>
#!/usr/bin/perl
# sample program that demonstrates how to write the CDRs to a log file
use strict;
use IO::Socket;
use IO::Handle;
my $logfile = "/home/jan/cdr.log"; # CHANGE THIS
my $gk_host = "localhost";
my $gk_port = 7000;
my $gk_pid;
if ($gk_pid = fork()) {
# parent will listen to gatekeeper status
sleep(1); # wait for gk to start
my $sock = IO::Socket::INET->new(PeerAddr => $gk_host, PeerPort => $gk_port, Proto => 'tcp');
if (!defined $sock) {
die "Can't connect to gatekeeper at $gk_host:$gk_port";
}
$SIG{HUP} = sub { kill 1, $gk_pid; }; # pass HUP to gatekeeper
$SIG{INT} = sub { close (CDRFILE); kill 2, $gk_pid; }; # close file when terminated
open (CDRFILE, ">>$logfile");
CDRFILE->autoflush(1); # don't buffer output
while (!$sock->eof()) {
my $msg = $sock->getline();
$msg = (split(/;/, $msg))[0]; # remove junk at end of line
my $msgtype = (split(/\|/, $msg))[0];
if ($msgtype eq "CDR") {
print CDRFILE "$msg\n";
}
}
close (CDRFILE);
} else {
# child starts gatekeeper
exec("gnugk");
}
</PRE>
</P>
<P>Keep in mind that this is just an example to show the usage of the status port.
You can use the FileAcct module to log CDRs in a production system.</P>
<H3>GUI for the Gatekeeper</H3>
<P>There are several Graphical User Interface (GUI) frontends for the gatekeeper.</P>
<P>
<UL>
<LI>Java GUI<P>Developed by Jan Willamowius.
You can monitor the registrations and calls that go through the gatekeeper.
A right-click on a button gives you a pop up menu for that endpoint.</P>
<P>This GUI works with Java 1.0 built into most web browsers.
For security reasons the GUI must be run as a standalone application
or served by a web server on the same IP number as the gatekeeper
(you cannot run it as an applet via a local file).</P>
<P>The program is available at
<A HREF="http://www.gnugk.org/h323gui.html">GnuGk Java GUI</A></P>
</LI>
<LI>GkGUI<P>A new standalone Java program developed by
<A HREF="http://www.citron.com.tw/">Citron Network Inc.</A>
It requires Java 1.4. New features include:</P>
<P>
<UL>
<LI>Monitor multiple gatekeepers simultaneously.</LI>
<LI>Two view modes: Button List and Tree List.</LI>
<LI>Call Detail Record(CDR) and statistics.</LI>
<LI>GK Status Log.</LI>
<LI>Different colors for different endpoint types.</LI>
<LI>Modify gatekeeper configuration.</LI>
<LI>Forced unregister endpoints.</LI>
<LI>Save and print status log and CDR.</LI>
</UL>
</P>
<P>The GkGUI is released under GNU General Public License, available at

<H2><A NAME="statusportfiltering"></A> <A NAME="ss13.4">13.4</A> <A HREF="manual.html#toc13.4">Status Port Filtering</A>
</H2>
<P>Status port filtering facilitates control on the amount and type of output messages shown to the end user.
Filtering is done using regular expressions which are used to decide whether to include (show) or
exclude (ignore) an output message.
Filtering control is done using the following set of commands:</P>
<P>
<UL>
<LI><CODE>addincludefilter REGEX</CODE><BR>
Adds regular expression to the include list
</LI>
<LI><CODE>addexcludefilter REGEX</CODE><BR>
Adds regular expression to the exclude list
</LI>
<LI><CODE>removeincludefilter INDEX</CODE><BR>
Removes filter at given INDEX from the include list
</LI>
<LI><CODE>removeexcludefilter INDEX</CODE><BR>
Removes filter at given INDEX from the exclude list
</LI>
<LI><CODE>filter 1|0</CODE><BR>
Enable/Disable message filtering
</LI>
<LI><CODE>printincludefilters</CODE><BR>
Print include filter list
</LI>
<LI><CODE>printexcludefilters</CODE><BR>
Print exclude filter list
</LI>
</UL>
</P>
<P>In order to enable usage of predefined filters, new section named
<A HREF="manual-4.html#gkstatusfilteringsect">[GkStatus::Filtering]</A> has been
introduced. At this section, users can put all their predefined filters to be load when status port starts.</P>
<P>
<DL>
<DT><B>Example:</B><DD><P>
<BLOCKQUOTE><CODE>
<PRE>
[GkStatus::Filtering]
IncludeFilter=.+
ExcludeFilter=.RQ
</PRE>
</CODE></BLOCKQUOTE>
</P>
</DL>
</P>
<P>When filtering come active, by <CODE>filter 1</CODE> command, all messages will be shown but lines with ARQ, LRQ etc.
Same effect can be achieved by using the command line:
<BLOCKQUOTE><CODE>
<PRE>
addincludefilter .+
addexcludefilter .RQ
filter 1
</PRE>
</CODE></BLOCKQUOTE>
</P>
<P>Note that enable filtering when no filters are defined, automatically excludes all message output.</P>
