P3A Utility Optimizations

[DJAndries]

Improve STAR recovery rates by allowing reordering of metric attributes, and allowing reporting of alternative, optional attributes. Each metric would have its own configuration. This feature will allow stakeholders to choose the necessary trade-offs for each metric.

Alternative attributes would include:

• region and subregion: from UN M49 region/subregion list (i.e. region = Americas, subregion = North America)
• general_platform: platform identifier without the CPU architecture component

@DJAndries: Can you add test plan is the issue? Thanks!

• Verified the test plan from Add metric configuration and alternative metric attributes brave-core#26762

Step 2_PASSED

1. Confirmed that requests are being made to star-randsrv.bsg.brave.com to prepare Constellation metrics
2. Confirmed that the URL path is /instances/<cadence type>/randomness
3. Confirmed that when one request is sent for a particular cadence, check to see that metrics are being marked as "sent" as they are being sent to the server, by checking the correct "logs" object in local state.

44 typical/slow/express randomness requests are sent to this endpoint star-randsrv.bsg.brave.com

Step 1,2	Step 1, 2(1)	Step 1, 2(2)	Step 1, 2(2)

4. There are 36 metrics listed under logs_constellation_prep shown in the images below Step 4(1), Step 4(2) and Step 4(3)
   All the metrics under Logs and logs_constellation_prep are marked as sent:true, when we look at the https://star-randsrv.bsg.brave.com endpoint at the server, 36 typical metrics are sent to the server in the form of randomness instances as shown in the images above Step 1,2(1) and Step 1,2(2)

36 metrics are shown under logs_constellation_prep

Step 4(1)	Step 4(2)	Step 4(3)

5. Confirmed that no. of metrics shown under logs_constellation_prep_express are same as the no. of metrics shown under the star-randsrv.bsg.brave.com server endpoint as expected

logs_constellation_prep_express	star-randsrv.bsg.brave.com

6. Confirmed that no. of metrics shown under logs_constellation_prep_slow are same as the no. of metrics shown under the star-randsrv.bsg.brave.com server endpoint as expected

logs_constellation_prep_slow	star-randsrv.bsg.brave.com

Step 3_PASSED

Ensure final measurements are being sent to collector.bsg.brave.com. The URL path should be /<cadence type>. Before metrics are sent to this server, they should appear under constellation_logs, constellation_logs_express and constellation_logs_slow after being prepared (from the requests being made in step 2). As soon as the metrics are sent to the collector, the metric should disappear in the relevant local state object.

1. Confirmed that, before the metrics are sent to server they are prepared to sent and hence appear under logs_constellation_prep_express, logs_constellation_prep_slow and logs_constellation_prep after that the metrics are appear under constellation_logs, constellation_logs_express and constellation_logs_slow .
   But the metrics listed under constellation_logs, constellation_logs_express and constellation_logs_slow are removed once the metrics are sent to the server

2. Confirmed that the final measurements are sent to the endpoint collector.bsg.brave.com
   • Five slow metrics are sent to the endpoint collector.bsg.brave.com as expected
   • Two express metrics are sent to the endpoint collector.bsg.brave.com and there is one creative instance id under logs_constellation_prep_express
   • There is one creative cadence type metrics are sent to the endpoint collector.bsg.brave.com as expected
   • There are 36 typical metrics are sent to the endpoint collector.bsg.brave.com as there are 36 typical metrics are listed under Logs in brave://local-state file
