Overview

Package udp is a generated protocol buffer package.

It is generated from these files:

github.com/google/cloudprober/probes/udp/config.proto

It has these top-level messages:

ProbeConf

Package udp implements a UDP prober. It sends UDP queries to a list of targets and reports statistics on queries sent, queries received, and latency experienced.

Queries to each target are sent in parallel.

Functions

func Ping

func Ping(addr string, timeout time.Duration) (success bool, latency time.Duration, err error)

Ping sends a UDP "ping" to addr. Probe succeeds if the same data is returned within timeout. TODO: Hide this once b/32340835 is fixed, that is, once nobody using it anymore.

Types

type Probe

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

Probe holds aggregate information about all probe runs, per-target.

func (*Probe) Init

func (p *Probe) Init(name string, tgts targets.Targets, interval, timeout time.Duration, l *logger.Logger, v interface{}) error

Init initializes the probe with the given params.

func (*Probe) Start

func (p *Probe) Start(ctx context.Context, dataChan chan *metrics.EventMetrics)

Start starts and runs the probe indefinitely.

type ProbeConf

type ProbeConf struct {
	// Export stats after these many milliseconds
	StatsExportIntervalMsec *int32 `` /* 138-byte string literal not displayed */
	// Port to send UDP Ping to (UDP Echo).  Should be same as
	// ProberConfig.udp_echo_server_port.
	// TODO: Can we just read this from ProberConfig?
	Port             *int32 `protobuf:"varint,3,opt,name=port,def=31122" json:"port,omitempty"`
	XXX_unrecognized []byte `json:"-"`
}
