Verifying cache usage

[gilm0079]

I'm pretty new to Redis. I'm working to add it to our Identity Server project. I have a Redis server up and running. The cache is attached in Identity Server as far as I can tell. I'd like to perform some sort of GET against the Redis cache to see that the identity server objects are being written there. I'm assuming I need to know the key though in order to retrieve the objects from Redis. Do you have any ideas on this?

I added an API controller I can execute against in the Identity server project so I can query into Redis. Inside the controller action I have it using the existing connectionMultiplexer. I tried a wildcard search, but either it is not working or there are no entries in Redis. Thoughts?

ICacheManager cacheClient = new RedisCacheManager(cacheConnection);
List<string> allKeys = cacheClient.SearchKeys("*").ToList();
