Make a Glances API in order to use Glances as a Python lib

[nicolargo]

Implement a new experimental Glances lib (target release for a stable API will be Glances 5.0).

Example:

import glances

gl = glances.GlancesAPI()

gl.cpu
print(gl.cpu)
print(gl.cpu['total'])


gl.network.update()
print(gl.network)
print(gl.network[''wlp0s20f3']['bytes_recv'])

The Glances class:

• can be local (retrieve stats directly)
• can be use as a proxy to a restfull (or rpc) Glances server
• Configuration file and args should be implemented

Documentation of the library is a key point.
