Frequently asked questions

How do I update the Latencetech solution ?

Please refer to the Update/Upgrade and Rollback procedures.

How can you prove that your measures are accurate ?

Prior to each release, we conduct accuracy tests, which include the following:

A comparison with industry accepted tools such as (Ookla’s Speedtest).
We introduce predefined set of network variations such as a bandwidth bottlenecks or congestion levels, each followed by test sessions where with compare measurements with the expected results.
The introduction of predefined delays, followed by a comparison of our latency measurements with the anticipated outcome.

To meet the acceptance criteria, these measurements must exhibit a maximum difference of 2% from the reference values.

Can I run only one protocol at a time ?

Yes. 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.

Can I use multiple QoS agents at the same time pointing to the same reflector ?

Yes, is it possible to use multiple QoS agents. It is mandatory to specify a different ID for each agent using LTI_agent_id. If not, you will not be able to identify the data related to a specific QoS agent.

How can I delete my docker which is currently running ?

Please refer to the docker prune documentation.

Does your solution encounter problems with data privacy ?

We do not collect any personal information. It is possible to run the analyzer on premises.

Is it available in every country ?

Yes, there is no usage restriction in any country.

How do I restart the analyzer if it is not responding ?

Log into your analyzer VM.
Run the following commands:

cd lti_analyzer
docker compose down
docker compose up -d

I have no data displayed, how can I troubleshoot this situation ?

If your QoS-Agent is running but you are not receiving any data on your Analyzer, execute the following procedure to troubleshoot this situation:

For Users on AWS:

If your Analyzer run on an AWS virtual machine, run this script:

wget https://wget https://api.latence.ca/software/lti_protocol_debug_AWS.sh

Then run the script with this command:

sudo bash lti_protocol_debug_AWS.sh

For all other Users:

Download this troubleshooting script:

wget https://wget https://api.latence.ca/software/lti_protocol_debug.sh

Then run the script with this command:

sudo bash lti_protocol_debug.sh

I get this error when I use the API: `customerID is required`.

It is possible, depending on the environement you use, that the analyzer part of the query also need to be in quotation marks:

curl -H -k "x-api-key: your_api_key_here" -s "https://<analyzer_IP>:12099/api/v1/ci?agent_id=<agentID>&customer_id=<customerID>"

This solution can also be used for the agentID is required error.
