Mentioned in SAL (#wikimedia-operations) [2026-01-15T22:02:29Z] <cjming@deploy2002> Finished scap sync-world: Backport for [[gerrit:1227435|Update experiment code for JS, PHP SDKs testing of TK (T414528 T414530)]] (duration: 09m 23s)

Process for testing PHP SDK using Test Kitchen extension:

1. PHP experiment was configured and initiated yesterday on Japanese Wikipedia at 10% sampling
2. Experiment code for both SDKs was backported to 1.46.0-wmf.11 yesterday
3. Verified via Kafka topic streaming and running queries on analytics servers:

Confirmed that events were streaming in via:

kafkacat -C -b kafka-jumbo1010.eqiad.wmnet:9092 -t eqiad.product_metrics.web_base -o -100000 | grep PageVisitTestKitchen

Ran the following queries:

SELECT count(*)
FROM event.product_metrics_web_base
WHERE instrument_name = 'PageVisitTestKitchen'
AND year = 2026 AND month = 01 AND day = 16;

// Returns 27377

SELECT count(*)
FROM event.product_metrics_web_base
WHERE instrument_name = 'PageVisitTestKitchen'
AND experiment.assigned='control'
AND year = 2026 AND month = 01 AND day = 16;

// Returns 13052

SELECT count(*)
FROM event.product_metrics_web_base
WHERE instrument_name = 'PageVisitTestKitchen'
AND experiment.assigned='control-2'
AND year = 2026 AND month = 01 AND day = 16;

// Returns 14325

With confirmations above, I will turn off experiment and remove related code.
