Use OpenTelemetry to collect and log client-side data

[Avery-Dunn]

OpenTelemetry is a product that can help create consistent telemetry collection

• Use OpenTelemetry to collect and log the same data we are currently collecting
• Add public API to allow developers to opt-in to getting OpenTelemetry data.
• Capture metrics for success counter with tags client id, token source and cache refresh reason.
• Capture metrics for failure counter with tags client id, error code.

Extra, depending on whether or not we can integrate it into existing data streams:

• Add database to collect the datapoints
• Use the logged data to identify common issues (not using cache, long HTTP times, etc.)
