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.
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
