Could you elaborate? How does knowing numerical usage metrics help?

With Phoenix + Clickhouse being fed from Otel, you can do queries over your traces for deep analysis. If I want to see which tool calls are failing and why (or just get tool statistics), or find common patterns in flagged/failure traces ("simpler solution") and their causes, it's one query and some wiring.

you mention traces

but the documentation only specifies metrics and logs

https://docs.claude.com/en/docs/claude-code/monitoring-usage

am i missing something here? or is this a case where they were lazy to do traces in the claude code sdk, so its logs + log attributes?

		You can get traces out of every agent framework that doesn't suck. You might need to collect from a proxy to get them from Claude because Anthropic is bigtime amateur hour.
