python-hwinfo
======
This is a python library for inspecting hardware and devices by parsing
the outputs of system utilities such as lspci and dmidecode.
Installation
------------
This package can be installed using pip either directly from this repository
or from the latest published version on PyPi:
pip install python-hwinfo
Or,
pip install git+https://github.com/rdobson/python-hwinfo.git
Library Usage
-----
The library consists of a number of command parsers, and a number of higher-level
objects. The parsers simply return a record, or a list of records associated with
a particular command output. The higher-level objects are populated with the records
obtained from a command output and include additional logic.
For example, to parse a list of PCI devices:
from hwinfo.pci import PCIDevice
from hwinfo.pci.lspci import LspciNNMMParser
from subprocess import check_output
# Obtain the output of lspci -nnmm from somewhere
lspci_output = check_output(["lspci", "-nnmm"])
# Parse the output using the LspciNNMMParser object
parser = LspciNNMMParser(lspci_output)
device_recs = parser.parse_items()
# Instantiate the records as PCI devices
pci_devs = [PCIDevice(device_rec) for device_rec in device_recs]
# Use the PCIDevice class to query info for subdevices
for dev in pci_devs:
if dev.is_subdevice():
print dev.get_info()
CLI
---
Along with the classes for parsing/inspecting objects, the library also includes
a simple CLI tool which can be used for inspecting local, remote and captured hosts.
For inspecting the hardware present on a local machine, execute:
$> hwinfo
$>

_Note: you may need to execute `hwinfo` with sudo depending on your systems permissions._
For remote executions you must provide a machine address, username and password:
$> hwinfo -m 10.80.100.152 -u root -p password
If you have the captured outputs of the following:
* /proc/cpuinfo as 'cpuinfo'
* dmidecode as 'dmidecode.out'
* lspci -nnm as 'lspci-nnm.out'
Then you can run `hwinfo` on that data in the following way:
$> hwinfo -f
Reporting Issues
----------------
This library is currently regarded as being in beta and so bugs are to be fully expected.
