twamp_reflector collector¶

twamp_reflector is the Two-way Active Measurement Protocol(TWAMP) reflector for the channel SLA measurements. Usually it accompanies the twamp_sender, although can serve as reflector for other TWAMP-compatible implementations.

Configuration¶

The common collector's configuration is:

Parameter	Type	Default	Description
`id`	String		Collector's ID. Must be unique per agent instance.
`type`	String		Must be `twamp_reflector`
`interval`	Integer	`agent.defaults.interval`	Repetition interval in seconds
`labels`	Object		Additional collector-level labels
`relabel`	Array		Optional relabeling rules. See Relabeling Rules for details

The collector-specifig configuration is:

Parameter	Type	Default	Description
`listen`	String	`0.0.0.0`	Address to bind the control channel
`port`	Integer	`862`	Port for the control channel

Config example:

- id: TWAMP Reflector
  type: twamp_reflector
  listen: "0.0.0.0"
  port: 862

Collected Metrics¶

OpenMetrics

Metric	Metric Type	Description
`twamp_session_attempts`	Counter	Total amount of the attempted sessions
`twamp_session_started`	Counter	Total amount of the started sessions
`twamp_reflected_pkt`	Counter	Total amount of the reflected packets
`twamp_reflected_octets`	Counter	Total amount of the reflected octets

Labels¶

twamp_reflector collector doesn't append its labels, though they can be configured via labels option.

Configuring Senders¶

Gufo Agent¶

collectors:
    - id: TWAMP Session
      type: twamp_sender
      interval: 10
      reflector: 127.0.0.1
      port: 862
      n_packets: 200
      model: g711
      dscp: ef
      labels:
        service: voip

See twamp_sender for configuration options details.
