	// GetInterfaceIndex gives read-only access to map with metadata of all configured
	// linux interfaces.
	GetInterfaceIndex() ifaceidx.LinuxIfMetadataIndex
}

API defines methods exposed by Linux-IfPlugin.

type Config

type Config struct {
	Disabled      bool `json:"disabled"`
	GoRoutinesCnt int  `json:"go-routines-count"`
}

Config holds the ifplugin configuration.

type Deps
