The kamon-cassandra module requires you to start your application using the Kanela Agent. Kamon will warn you at startup if you failed to do so.

The bytecode instrumentation provided by the kamon-cassandra-client module hooks into the Cassandra Driver to automatically gather Metrics and start and finish Spans for requests that are issued within a trace. This translates into you having metrics about how the requests you are doing are behaving.

Kamon Cassandra module is currently available for Scala 2.11 and 2.12.

Supported releases and dependencies are shown below.

To get started with SBT, simply add the following to your build.sbt file:

libraryDependencies += "io.kamon" %% "kamon-cassandra-client" % "1.0.6"

The following metrics will be recorded:

• cassandra_query_count_total
• cassandra_client_inflight_driver_bucket
• cassandra_trashed_connections_bucket
• cassandra_connection_pool_size_bucket
• cassandra_query_duration_seconds_bucket
• cassandra_client_inflight_bucket
