What is jitsi-meet-metrics-collector ?

jitsi-meet-metrics-collector is a Node.js module that serves as a middleware for Express.js. It collects browser metrics and stores them in MongoDB database.

How does it work ?

once the user opens a web conference the jmmc_client.js file is uploaded and appended to the client script,the first post request send user's meta-data, the second sends metrics data (connectionquality,bandwidth...),and each 30 seconds after that it sends just the updated (changed)metrics.

sequenceDiagram
Browser->>jitsi-meet-metrics-collector: Get the JS file that sends metrics from /getClient
jitsi-meet-metrics-collector->>Browser: Send client JS file
loop Sending requests every X seconds (Default: 30s)
    Browser->>jitsi-meet-metrics-collector: Send metrics
    jitsi-meet-metrics-collector->>jitsi-meet-metrics-collector: Verify and Validate metrics
    jitsi-meet-metrics-collector->>MongoDB: Store metrics
    MongoDB->>jitsi-meet-metrics-collector: Send confirmation
    jitsi-meet-metrics-collector->>Browser: Send confirmation
        
end

example :

• the fist request. the script sends the browser, the operating system and pid
• the second request it sends metrics data containing for exemple cq (stands for connexion quality)
• after that if the connexion quality change it sends metrics with the changed data if not it sends just the updated data without cq.
