Dear all,
I want to monitor the registration status of (PJ)SIP peers providing SIP trunks to an asterisk system.
I would like to do this in a robust / decent way rather than manually parsing the output of asterisk -rx sip show peer.
What would be the state-of-the-art to go here?
Check Device state or use AMI for Real time monitoring from external source
Thanks for your suggestions. I will go for AMI then, since I already use AMI but with rudimentary scripts written with Tcl/Tk’s expect.
I want to go for Python as language, but I did not succeed in having it running so far.
I tried https://github.com/asterisk/starpy. I tried to build the documentation by running doc/pydoc/builddocs.py. The script returns with an error:
Start 'starpy'
... found 'starpy'
Traceback (most recent call last):
File "builddocs.py", line 25, in <module>
recursionStops=stops,
File "/root/starpy/doc/pydoc/pydoc2.py", line 402, in process
packageContext=self,
File "/root/starpy/doc/pydoc/pydoc2.py", line 159, in docmodule
for file in os.listdir(object.__path__[0]):
OSError: [Errno 20] Not a directory: '/usr/local/lib/python2.7/dist-packages/starpy-1.0.3-py2.7.egg/starpy'
Apparently, the script assumes the package to be a directory, while it actually is a file.
Furthermore, I tried the examples. The HTML documentation tells utilapplication and basicproperty. The latter apparently is 13 years old and not compatible with Python 2.7:
Collecting basicproperty
Could not find a version that satisfies the requirement basicproperty (from versions: )
No matching distribution found for basicproperty
I tried to find additional information, the documentation references http://starpy.sourceforge.net, but that has not been updated since 2008.
in the past was looking for similar task : monitor peers registration status.
ended up with a php PAMI script, running on asterisk server and listening to the events, then writes event to the mysql database for reporting and drawing charts with peer presence on a time line ( Used to track working time of the call center operators )
First - configured AMI access ( asterisk/manager.conf) ,
next - created mysql table ‘realstatus’ :
±--------------±-------------±
| Field | Type |
±--------------±-------------±
| id | int(11) |
| ts | timestamp |
| sip_name | varchar(100) |
| event_type | varchar(100) |
| event_data | varchar(100) |
| event_details | varchar(100) |
| session_time | int(11) |
±--------------±-------------±
Script, which attaches to the AMI interface and keep listening events:
<?php
ini_set('display_errors', 1);
error_reporting(1);

$pamiClient = new PamiClient($pamiClientOptions);
$mysqli = new mysqli("localhost","asteriskuser","asterpass","asterisk");
if($mysqli -> connect_errno)
die( "Failed to connect to MySQL: " . $mysqli -> connect_error );
// Open the connection
$pamiClient->open();

$running = true;
while($running) {

$signals_txt = array ( 'RINGING' => 180,
'PROGRESS' => 183 );
echo " DIAL STATUS: {$PEER} {$event['dialstatus']} {$signals_txt[$event['dialstatus']]} for {$event['destchannel']} \r\n";
}
To get this script running even after asterisk restart, on system boot, I’ve made initd script:
/etc/init.d/peerstatusd
#! /bin/sh
#/etc/init.d/$PROG
#
PROG=peerstatusd
SCRIPT='online.php'
LOG=/dev/null
#LOG=/var/log/peerstatus.log
# Some things that run always
touch /var/lock/
# Carry out specific functions when asked to by the system
case "$1" in
start)
echo "Starting $PROG "
$(while true
do
sleep 1
echo " Starting $PROG .."
cd /var/www/html/ && while true; do php online.php; done >> $LOG 2>&1 || echo "Failed to start $PROG"
done) &
;;
stop)
echo "Stopping script $SCRIPT"
PID=`ps ax -o pid,cmd|grep "php ${SCRIPT}" | grep -v grep |awk '{print($1)}'`
[ "${PID}s" != "s" ] && kill -9 $PID && echo "Stopped ${SCRIPT} PID: ${PID}"
killall -9 $PROG
;;
*)
echo "Usage: /etc/init.d/$PROG {start|stop}"
exit 1
;;
esac
exit 0
enabled it by :
chkconfig peerstatusd on
logs and table records:

it shows recent registry session, and total for today in the report.
If some one interested , will answer private messages with more details
Thanks for your input!
Meanwhile, I tried this Python AMI client:
I managed to to solve the issue and implemented a check script as follows:
