@lukemun there are no cache spans in the trace associated with organizations.

I do not believe flask-caching is integrated with Sentry's cache spans yet (or if it is, it may require a config setting?).

Let's bring this question up with the SDK team.

The problem was CACHE_KEY_PREFIX in config auto added 'flask_cache_" to the key while sentry_sdk was expecting RedisIntegration(cache_prefixes=["flask.", "ruby."]).

Tested locally with additional prefix removed and it's coming through on the cache page.

[lukemun]

Resolved.

tldr: cache_prefix must match the one in Sentry SDK RedisIntegration(). flask_caching library adds a default which threw things off.
