kamon-redis: kamon.instrumentation.akka.filters.actors.trace.excludes is not picked

[jtjeferreira]

Hi!

I was trying the kamon-redis module with redisscala and everything is working fine, except a small detail regarding the traces:

Those Tell operations they are still present in the trace, although these traces are excluded in this code

Kamon/instrumentation/kamon-redis/src/main/resources/reference.conf

Lines 21 to 29 in c6a32e7

	# when using multiple clients, the extension will be alphabetical
	# e.g. $a, $b, $c.
	# so add exclude clauses as needed
	kamon.instrumentation.akka.filters.actors.trace {
	excludes += "*/user/RedisClient-$a/**"
	excludes += "*/user/RedisClient-$a"
	excludes += "*/user/RedisBlockingClient-$a/**"
	excludes += "*/user/RedisBlockingClient-$a"
	}

In the REPL, I can see those configs are not picked:

scala> kamon.Kamon.config().getConfig("kamon.instrumentation.akka.filters.actors.trace")
val res7: com.typesafe.config.Config = Config(SimpleConfigObject({"excludes":[],"includes":["*/user/**","*/system/sharding**"]}))

scala> kamon.Kamon.config().getConfig("kanela.modules.redis")
val res8: com.typesafe.config.Config = Config(SimpleConfigObject({"description":"Provides tracing for Jedis, Lettuce and Rediscala libraries","instrumentations":["kamon.instrumentation.jedis.JedisInstrumentation","kamon.instrumentation.lettuce.LettuceInstrumentation","kamon.instrumentation.rediscala.RediscalaInstrumentation"],"name":"Redis Instrumentation","within":["redis.clients.jedis.Protocol","io.lettuce.core..*","redis..*"]}))

I suspect this is due to some loading order of the reference.conf files, because adding the above configuration to my application.conf file fixes the problem...

This seems to happen only when adding the dependencies one-by-one, instead of using the bundle. Fixing it in a bit.

This will get fixed with #1122 😄
