Additional context

I have recently been working on a project that required Redis instrumentation for two different languages. During this process, I noticed some discrepancies in the attributes being collected. To investigate further, I conducted testing to check the attributes collected for Redis instrumentation across six of the most popular languages. I have documented my testing in this GitHub repository:

Findings for PHP:

What We Capture Today ==> How It Should Look in Latest Semantic Conventions

server.address: 127.0.0.1 ==> server.address: 127.0.0.1 network.transport: tcp ==> Not sure if it's needed server.port: 6379 ==> server.port: 6379 db.system: redis ==> db.system: redis db.statement: ==> db.statement: GET simple_text_message (Not captured) ==> db.redis.database_index: 0
