Hello,

in our project, we use the Microsoft.Extensions.Caching.Distributed package for configuring the Redis cache like shown in this code snippet:

```auto
services.AddStackExchangeRedisCache(options =>
{
  options.Configuration = "redis.local:6379";
  options.InstanceName = "XF";
});

```

Is there any possibility to get it working with Elastic.Apm.StackExchange.Redis? I tried several things but was not able to get it work.

Best regards,  
Thorsten

Hi @ThorstenKraus,

`Elastic.Apm.StackExchange.Redis` targets the `StackExchange.Redis` package - so if you use redis via `StackExchange.Redis`, then I it should work. Your code snippet does not tell much, but based on `services.AddStackExchangeRedisCache` I suspect you use this package.

You need to have access to the `IConnectionMultiplexer` from Redis and call `.UseElasticApm` on it (that method is in the `Elastic.Apm.StackExchange.Redis` package.

Docs here: [StackExchange.Redis | APM .NET Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/dotnet/current/setup-stackexchange-redis.html)

Do you have access to `IConnectionMultiplexer` over the `options` variable? If so, then just call the method - if you don't, then I suggest the approach should be that you try to figure out how you can have access to the `IConnectionMultiplexer` so you can register the APM Agent with it.

Hi @GregKalapos ,

thank you very much for your answer!

As far as I see I don't have access to the IConnectionMulitplexer over the options variable. But it seems to be possible to access an property called 'ConnectionMultiplexerFactory' over the options variable. I tried to use this but unfortunately with no success. The first line of code results in a NullReferenceException.

```auto
IConnectionMultiplexer connectionMultiplexer = ConnectionMultiplexer.Connect("localhost:6379");
                services.AddSingleton(connectionMultiplexer);
                services.AddStackExchangeRedisCache(options =>
                {
                    options.ConnectionMultiplexerFactory = () => Task.FromResult(connectionMultiplexer);
                });

```

Do you have any idea how to get this working? It would be wonderful if you would have an code snippet for me so that I can have a look at it and try to adapt my code. Hint: I have some business logic services which expect an IDistributedCache (from Microsoft.Extensions.Caching.Distributed) in their constructor and they get this via dependency injection - this way is needed also in future.

Best regards,  
Thorsten
