Hi,
Thank you. I stuck just into passed config_dict.
How can I pass this value into my driver ?
In documentation, he say that create class like this :
class MyAlarm(StdService):
"""Service that sends email if an arbitrary expression evaluates true"""
def __init__(self, engine, config_dict):
Thank's
