Functions ¶
func GetHostname ¶
GetHostname returns the hostname for the given IP address as a string.
func GetReverseDNSForIP ¶
GetReverseDNSForIP returns the reverse DNS for the given IP address as a net.IP.
Types ¶
type Config ¶
type Config struct {
// TODO: add common configuration
// Destination Hostname
DestHostname string
// Destination Port number
DestPort uint16
// Destination service name
DestinationService string
// Source service name
SourceService string
// Source container ID
SourceContainerID string
// Max number of hops to try
MaxTTL uint8
// TODO: do we want to expose this?
Timeout time.Duration
// Protocol is the protocol to use
// for traceroute, default is UDP
Protocol payload.Protocol
}
Config specifies the configuration of an instance of Traceroute
type LinuxTraceroute ¶
type LinuxTraceroute struct {
// contains filtered or unexported fields
}
LinuxTraceroute defines a structure for running traceroute from an agent running on Linux
func New ¶
func New(cfg Config, _ telemetry.Component) (*LinuxTraceroute, error)
New creates a new instance of LinuxTraceroute based on an input configuration
func (*LinuxTraceroute) Run ¶
func (l *LinuxTraceroute) Run(_ context.Context) (payload.NetworkPath, error)
Run executes a traceroute
type Runner ¶
type Runner struct {
// contains filtered or unexported fields
}
Runner executes traceroutes
func NewRunner ¶
func NewRunner(telemetryComp telemetryComponent.Component) (*Runner, error)
NewRunner initializes a new traceroute runner
func (*Runner) RunTraceroute ¶
RunTraceroute wraps the implementation of traceroute so it can be called from the different OS implementations
This code is experimental and will be replaced with a more complete implementation.
type Traceroute ¶
type Traceroute interface {
Run(context.Context) (payload.NetworkPath, error)
}
Traceroute defines an interface for running traceroutes for the Network Path integration
