init(self, single=True)
(Constructor)

source code

Initalizer

Parameters:

single (boolean) - collect from a single device?

Overrides: ZenUtils.CmdBase.CmdBase.__init__

config(self)

source code

Get the DiscoverService

Returns: function: a DiscoverService from zenhub
Overrides: zenmodeler.ZenModeler.config

discoverIps(self, nets)

source code

Ping all ips, create entries in the network if necessary.

Parameters:

nets (list) - list of networks to discover

Returns: Twisted deferred

successful result is a list of IPs that were added

discoverRanges(self, driver)

source code
