type Reporter

type Reporter struct {
	// contains filtered or unexported fields
}

Reporter generates Reports containing the Endpoint topology.

func NewReporter

func NewReporter(hostID, hostName string, includeProcesses bool, useConntrack bool, scanner procspy.ConnectionScanner) *Reporter

NewReporter creates a new Reporter that invokes procspy.Connections to generate a report.Report that contains every discovered (spied) connection on the host machine, at the granularity of host and port. That information is stored in the Endpoint topology. It optionally enriches that topology with process (PID) information.

func (Reporter) Name added in v0.10.0

func (Reporter) Name() string

func (*Reporter) Report

func (r *Reporter) Report() (report.Report, error)
