var ConntrackModulePresent = func() bool { f, err := os.Open(modules) if err != nil { return false } defer f.Close() scanner := bufio.NewScanner(f) for scanner.Scan() { line := scanner.Text() if strings.HasPrefix(line, conntrackModule) { return true } } if err := scanner.Err(); err != nil { log.Errorf("conntrack error: %v", err) } log.Errorf("conntrack: failed to find module %s", conntrackModule) return false }
ConntrackModulePresent returns true if the kernel has the conntrack module present. It is made public for mocking.

Types ¶
type Reporter ¶
type Reporter struct {
// contains filtered or unexported fields
}
Reporter generates Reports containing the Endpoint topology.
func NewReporter ¶
func NewReporter(hostID, hostName string, spyProcs, useConntrack, walkProc 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.
