OpenTelemetry ext-rdkafka auto-instrumentation ============================================== [](#opentelemetry-ext-rdkafka-auto-instrumentation) Please read for instructions on how to install and configure the extension and SDK. Overview -------- [](#overview) Auto-instrumentation hooks are registered via composer. There will be a new span created for each message that is consumed. The goal of this instrumentation is to allow distributed traces to happen across Kafka in PHP. This means that the following should happen: - A span should be created for each message that is consumed - The span should be created with the correct parent context- should the inbound message contain a traceparent header - The span should be ended when the message offset is `committed` - Any messages produced should have the traceparent header injected into the message headers This is done by hooking into three methods: - `\RdKafka\KafkaConsumer::consume`- For span creation and context propagation on inbound messages. - `\RdKafka\ProducerTopic::producev`- For injecting the traceparent header into the message headers of produced messages. - Note there is an old method called `produce`. This does not support headers, and thus there was no point hooking into this - `\RdKafka\KafkaConsumer::commit` / `\RdKafka\KafkaConsumer::commitAsync` - For ending the span when the message offset is committed. Versions -------- [](#versions) - Tested on PHP 8.2 and 8.3 with success Configuration ------------- [](#configuration) The extension can be disabled via [runtime configuration](https://opentelemetry.io/docs/instrumentation/php/sdk/#configuration): ``` OTEL_PHP_DISABLED_INSTRUMENTATIONS=ext-rdkafka ``` ### Health Score 51 — FairBetter than 95% of packages Maintenance93 Actively maintained with recent releases Popularity36 Limited adoption so far Community17 Small or concentrated contributor base Maturity47 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
