Instance Methods

[hide private]

__init__(self)
Initializer that takes care of basic daemon options.

source code

list of dictionaries

loadDeviceList(self, args=None)

source code

applyZProps(self, device, device_specs)
Apply zProperty settings (if any) to the device.

source code

applyOtherProps(self, device, device_specs)
Apply non-zProperty settings (if any) to the device.

source code

processDevices(self, device_list)
Read the input and process the devices * create the device entry * set zproperties * model the device

source code

list of dictionaries

parseDevices(self, data)
From the list of strings in rawDevices, construct a list of device dictionaries, ready to load into Zenoss.

source code

dictionary

parseDeviceEntry(self, line, defaults)

init(self)
(Constructor)

source code

Initializer that takes care of basic daemon options. Creates a PID file.

Overrides: ZenUtils.CmdBase.CmdBase.__init__

loadDeviceList(self, args=None)

source code

Read through all of the files listed as arguments and return a list of device entries.

Parameters:

args (list of strings) - list of filenames (uses self.args is this is None)

Returns: list of dictionaries

list of device specifications

applyZProps(self, device, device_specs)

source code

Apply zProperty settings (if any) to the device.

Parameters:

device (DMD device object) - device to modify
device_specs (dictionary) - device creation dictionary

applyOtherProps(self, device, device_specs)

source code

Apply non-zProperty settings (if any) to the device.

Parameters:

device (DMD device object) - device to modify
device_specs (dictionary) - device creation dictionary

processDevices(self, device_list)

source code


Read the input and process the devices
  * create the device entry
  * set zproperties
  * model the device

@parameter device_list: list of device entries
@type device_list: list of dictionaries

getDevice(self, device_specs)

source code

Find or create the specified device

Parameters:

device_specs (dictionary) - device creation dictionary

Returns: DMD device object

device or None

buildOptions(self)

source code

Add our command-line options to the basics

Overrides: ZenUtils.CmdBase.CmdBase.buildOptions

parseDevices(self, data)

source code

From the list of strings in rawDevices, construct a list of device dictionaries, ready to load into Zenoss.

Parameters:

data (list of strings) - list of strings representing device entries

Returns: list of dictionaries

list of parsed device entries

parseDeviceEntry(self, line, defaults)

source code

Build a dictionary of properties from one line's input

Parameters:

line (string) - string containing one device's info
defaults (dictionary) - dictionary of default settings

Returns: dictionary

parsed device entry
