Project Description

Netshow is Network Abstraction Software. It is optimized to collect core networking data from devices that contain many network interfaces.

The netshow core respository has 2 main components:

netshow-core-lib:

This is core library for retrieving network information from a device and abstracting it into Python objects.

Its core module is called netshowlib. It contains a few high levels such as iface() and system_summary(), that when called, this calls a provider that retrieves the information from the system.

A provider is module that interacts with the base system and converts relevant network information into python objects. For example, the Linux provider, when the netshow-core-lib iface() is called, can retrieve network information like MTU, speed, IP address from device running a Linux kernel.

Example:

With the Linux provider, retrieve details about the eth1 interface

import netshowlib.netshowlib as nn
eth1 = nn.iface('eth1')
>>> eth1.ip_address.allentries
[u'192.168.50.11/24']
>>> eth1.lldp
[{'adj_port': 'swp4', 'adj_mgmt_ip': '192.168.121.242', 'adj_hostname':
'clswitch'}]
>>> eth1.is_trunk()
True
>>> eth1.is_l3()
True
>>>

netshow-core:

Netshow is responsible printing and analysing the information collected from the library component of netshow. netshow-core is the core component of this functionality and uses providers (plugins) to properly print and analyse gathered by the netshowlib component of the provider(plugin). For example, the print_iface wrapper class in the Linux netshow provider, is responsible for printing linux network information collected by the Linux provider netshowlib modules.
