A simple check for check_mk to monitor OSCam. Queries the xmlAPI of oscam and mangels the output to match check_mk's expectation.

Tested on

OSCAM: 1.20-unstable_svn Build: r9783 Compiler: x86_64-linux-gnu

Setup

Find your local script path

$ check_mk -d | head
<<>>
Version: 1.2.4p5
AgentOS: linux
PluginsDirectory: /usr/lib/check_mk_agent/plugins
LocalDirectory: /usr/lib/check_mk_agent/local
...

Put the Script in place on your oscam server

Copy & paste the script below to LocalDirectory. Change the API connection details. Change the service status definitions if you want to.

Run an inventory scan on your monitoring system:

# check_mk -I
local             1 new checks

oscam.py

#!/usr/bin/python

import requests
from requests.auth import HTTPDigestAuth
import xmltodict

# API connection details
url      = 'http://localhost:16002/oscamapi.html?part=status'
username = ''
password = ''

# define service status by "bad" cards
ok   = '0';   # service is OK if 0 bad cards
warn = '4';   # service is WARN if greather or equal than n bad card

filtered = dict()

def receive():
  data = requests.get(url, auth=HTTPDigestAuth(username, password)).content
  data = xmltodict.parse(data)
  return data

def filter(e, filtered):
  if e['@type'] == 'p' or e['@type'] == 'r':
    filtered[e['@name']] = e['connection']['#text']

xml = receive()
for i in xml['oscam']['status']['client']:
  filter(i, filtered)

cardsTotal = len(filtered)
cardsGood = sum(1 for x in filtered.values() if x == 'CARDOK' or x == 'CONNECTED')
cardsBad = cardsTotal - cardsGood

state = 0
if cardsTotal - cardsGood >= warn:
  state = 1
if filtered['easymouse-local'] != 'CARDOK':
  state = 2

print '%d oscam_cards count=%d|good=%d|bad=%d %d cards, %d bad, %d good' % (state, cardsTotal, cardsGood, cardsBad, cardsTotal, cardsBad, cardsGood)
