module: skydive_capture
version_added: "2.8"
author:
- "Sumit Jaiswal (@sjaiswal)"
short_description: Module which manages flow capture on interfaces
description:
- This module manages flow capture on interfaces. The Gremlin
expression is continuously evaluated which means that it is
possible to define a capture on nodes that do not exist yet.
- It is useful when you want to start a capture on all OpenvSwitch
whatever the number of Skydive agents you will start.
- While starting the capture, user can specify the capture name,
capture description and capture type optionally.
requirements:
- skydive-client
extends_documentation_fragment: skydive
options:
query:
description:
- It's the complete gremlin query which the users can input,
I(G.V().Has('Name', 'eth0', 'Type', 'device')), to create
the capture. And, if the user directly inputs the gremlin
query then user is not required to input any other module
parameter as gremlin query takes care of creating the flow
capture.
