Script for using MCollective's mco client and Foreman's API to check server visibility between the two systems. I obviously want all hosts in Foreman/Puppet to be visible via MCollective too. This simple Python script does a check for me, printing a list of servers that aren't visible between both systems (missing from one or the other). The onl…

import requests, shlex, json
from subprocess import Popen, PIPE

class MCollective:
    
    def list_hosts(self):
        process = Popen(shlex.split("mco rpc rpcutil ping -j"), stdout=PIPE)
        j       = process.communicate()[0]

        process.wait()

        if j:
            return [ i['sender'].split('.')[0] for i in json.loads(j) ]
        else:
            return None

class Foreman:

    def __init__(self, hostname=None, username=None, password=None):
        self.username   = username
        self.password   = password
        self.hostname   = hostname

        self.perpage    = 100
        self.sslverify  = False

    def list_hosts(self):
        uri  = "{0}/api/hosts?per_page={1}".format(self.hostname, self.perpage)
        http = requests.get(uri, auth=(self.username, self.password), verify=self.sslverify)

        if http.status_code == 200:
            return [i['host']['name'].split('.')[0] for i in http.json()]
        else:
            return None

if __name__ == '__main__':
    # Use whatever passwords you need to.
    foreman_hosts       = Foreman('foreman', 'admin', 'chageme').list_hosts()
    mcollective_hosts   = MCollective().list_hosts()

    diff = [i for i in foreman_hosts if i not in mcollective_hosts]

    if len(diff) > 0:
        print diff
    else:
        print "All in sync."

For those wondering, it's written in Python and not Ruby (as Ruby has a native MCollective Ruby gem) because Python's requests library is some-what unmatched and works very well for me.
