Custom configurations

Sampling and other options can be set under the environment section of the lti_qos-agent.yml. Below is an example of all possible customizations.

Note: Any modification to the configuration file of a running docker needs to be followed by a restart of the docker by invoking the following command:

docker-compose -f lti_qos-agent.yml up -d

Interval options, for each protocol

    environment:

      # Interval between bandwidth measures, in seconds -- min: 60
      - LTI_iperf3_session_interval=7200

      # Interval between traceroute measures, in seconds -- min: 60
      - LTI_traceroute_interval=300.0

      # Interval between HTTP measures, in seconds -- min: .01
      - LTI_http_interval=2.0

      # Interval between HTTPs measures, in seconds -- min: .01
      - LTI_https_interval=2.0

      # Interval between TCP measures, in seconds -- min: .01
      - LTI_tcp_interval=2.0

      # Interval between UDP measures, in seconds -- min: .01
      - LTI_udp_interval=2.0

      # Interval between ICMP measures, in seconds -- min: .01
      - LTI_icmp_interval=2.0

      # Interval between TWAMP sessions, in seconds -- min: 1
      - LTI_twamp_session_interval=1    

Note: It is possible to disable a protocol by setting its sampling rate to -1. E.g. specifying LTI_iperf3_session_interval=-1 will disable iperf.

ICMP specific options

    environment:

      # ICMP timeout, in seconds
      - LTI_icmp_timeout=1

iPerf3 specific options

    environment:

      # UDP usage for bandwidth measurement
      # iperf3 equivalent option: -u
      - LTI_iperf3_udp=false

      # Duration of the iperf test (seconds) 
      # iperf3 equivalent option: -t
      - LTI_iperf3_test_duration=10

      # Length of buffer to read or write (default 128K for TCP or 1460 for UDP)
      # iperf3 equivalent option: -l
      - LTI_iperf3_buffer_length=128K

      # Target bitrate in bits/sec (0 for unlimited)
      # iperf3 equivalent option: -b
      - LTI_iperf3_bitrate=1M

      # Time interval between packets during a test (seconds)
      # ipef3 equivalent option: -i
      - LTI_iperf3_transmit_interval=1

Traceroute specific options

    environment:

      # Maximum hops
      - LTI_traceroute_max_hops=32

      # Maximum measures per hop
      - LTI_traceroute_measures_per_hop=3

TWAMP specific options

    environment:

      # Advanced padding option
      - LTI_twamp_packet_use_zero_pad=false

      # Packets per session -- min: 1
      - LTI_twamp_packet_count=15

      # Interval between packets, in milliseconds -- min: 1
      - LTI_twamp_packet_interval=100

      # Payload size, in bits -- min: 1
      - LTI_twamp_packet_payload=1024
