Script for getting isc-kea stats from control-socket

kea.py

#!/usr/bin/python
import socket,os,json

BUFF_SIZE = 1024
s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
s.connect("/var/kea/control.sock")
s.send('{"command":"statistic-get-all","arguments":{}}')
result = ""
part = s.recv(BUFF_SIZE)
while len(part) == BUFF_SIZE:
        result += part
        part = s.recv(1024)
result += part
json = json.loads(result)
resDict = {}
resDict[u'all_interfaces'] = dict([('total-addresses',0),('assigned-addresses',0),('declined-addresses',0),('declined-reclaimed-addresses',0),('reclaimed-leases',0),('reclaimed-declined-addresses',0)])
for k,v in json["arguments"].iteritems():
        k = k.split('.') 
        interface = k[0].replace('subnet[','bat').replace(']','')
        if len(k) != 2:
                continue
        if interface not in resDict:
                resDict[interface] = dict()
        
        resDict[interface][k[1]] = v[0][0]
        resDict['all_interfaces'][k[1]] += v[0][0]

for k,v in resDict.iteritems():
        print(k,v)
s.close()

Thanks! This saved me a ton of time trying to get a proof of concept to work from.

I created a quick&dirty PHP script to convert statistics to graphite format, maybe others will find it useful. Doesn't reset counters or actually send to graphite, but that's easy enough to add on.
