How to read zookeeper object

    FetchNSXStatus:
        Type: NSX
        TestNSX: "nsxmanager.[1]"
        PersistData: "Yes"
        read:
            'mem_total[?]defined': ''
	  
	  
	FetchSNMPHostResourcesMIB:
        Type: "SnmpManager"
        TestSnmpManager : "nsxmanager.[1].snmpmanager.[1]"
        manager_ip: 'nsxmanager.[1]'
        hostresourcesmib:
            'snmp_response':
                'HOST-RESOURCES-MIB::hrMemorySize."0"[?]equal_to' : 'nsxmanager[1]->read->mem_total'

1 Start the zookeeper server
/tmp/vdnet/20141020-181332/zookeeper-4668/bin/zkServer.sh start

2 Get the port number of server
cat /tmp/vdnet/20141020-181332/zookeeper-4668/conf/zoo.cfg
clientPort=2188

3 Start the zookeeper session
/tmp/vdnet/20141020-181332/zookeeper-4668/bin/zkCli.sh -server localhost:2188
