|
||||
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.
