Introduction:
This wiki page explains the design and implementation of how to log telemetry event to track the stage load time.
Background:
Currently, we are logging the Interact and Impression event before stage load but - we are not logging the telemetry event after the stage is successfully loaded.
- INTERACT event before the stage is loaded

- IMPRESSION event before the stage is loaded

Problem Statement:
Currently, we are not logging the telemetry event after the stage load. Because of this, we are not able to track the stage load time.
Solution 1:
We need to log the telemetry event after the stage is successfully loaded so that we can get the time between before and after stage load time.
Log the telemetry on stage "complete" event
loader.on("complete", function() {
// Log following telemetry event
}, null, !0),
Event Data
{
"edata": {
"type": "progress",
"level": "TRACE",
"message": "", // Required. Log message
"pageid": "stage_id",
"extra": {{"stageProgress":{
"id":"8c8d4b50-1c59-4355-8042-ae2a84769ab3",
"progress":"100%"
}}
}
}
}
