Hello All,

I am trying to use zabex.py library to create a new item and add data value like below but I am getting Invalid params, No Permissions error:

root@cast2:~# python zabex.py
[u'Zabbix server', u'cast2']
Traceback (most recent call last):

Looking for some urgent help.

hostid='cast2' doesn't look like real hostid. Hostid is integer, not a string.
