[Pyst-users] Trouble with sippeers

[Jeff L. <je...@je...>]

Hello,

I started what I hoped to be a simple hack this morning and found pyst.  
I would like to use the asterisk AMI to pull a list of SIP peers and 
their status.  I am doing this today on a number of our customer 
asterisk instances using bourne shell and "asterisk -x "sip show 
peers'", then parsing the output, but this is turning out to be quite an 
intensive act to perform on the instance, thus the desire to use AMI.

After a few hours of surfing and playing around, I have ended up with this:

--------------

root@jlpenha:/usr/local/bin# more pypeers
#!/usr/bin/python

from asterisk import manager
import signal

ip = "127.0.0.1"
user = "XXX"
passwd = "XXX"

peers = []

def handleEvent(event, ami):
     print ("Received event: %s" % event.name)

     if event.name == 'PeerlistComplete':
         printResults()
         ami.close()

     #print ("Received event Header: %s" % event.headers)
     #add to peers[]

def eventTimeout(signum, frame):
     print "Timeout!"
     ami.close()

def printResults():
     print peers

ami = manager.Manager()
ami.connect(ip)
ami.login(user, passwd)
ami.register_event('PeerEntry', handleEvent)
ami.register_event('PeerlistComplete', handleEvent)

signal.signal(signal.SIGALRM, eventTimeout) # Sippeers tends to hang?
signal.alarm(5)

response = ami.send_action({'Action' : 'Sippeers'})
ami.message_loop()

print response

---------------

In testing I first noticed that about 30% of the time the script hangs, 
thus I implemented the signal timeout.  It seems to hang because I never 
get the PeerlistComplete event.  Is this a problem with asterisk not 
sending it or some kind of bug in pyst?

I next noticed that I rarely get the same number of peers:

--------

root@jlpenha:/usr/local/bin# ./pypeers | wc -l
27
root@jlpenha:/usr/local/bin# ./pypeers | wc -l
68
root@jlpenha:/usr/local/bin# ./pypeers | wc -l
71
root@jlpenha:/usr/local/bin# ./pypeers | wc -l
67
root@jlpenha:/usr/local/bin# ./pypeers | wc -l
64

-------

This can't possibly be so difficult.  Surely someone has done what I am 
trying to do, though I haven't found any examples with lots of googling 
today.  Can anyone chime in?

Thanks!
