This project is a lightweight scala wrapper for the opencensus-java library and provides instrumentation for scala based frameworks.

The API documentation can be found here.

Opencensus-scala supports the tracing and stats apis of opencensus.

Add the following dependencies to your sbt project.

// If you want to use only the core module
"com.github.sebruck" %% "opencensus-scala-core" % "0.6.0" 

// Dependent on the trace exporters you want to use add one or more of the following
"io.opencensus" % "opencensus-exporter-trace-stackdriver" % "0.15.0"
"io.opencensus" % "opencensus-exporter-trace-logging"     % "0.15.0"
"io.opencensus" % "opencensus-exporter-trace-instana"     % "0.15.0"
"io.opencensus" % "opencensus-exporter-trace-zipkin"      % "0.15.0"

// If you want to use opencensus-scala inside an Akka HTTP project 
"com.github.sebruck" %% "opencensus-scala-akka-http" % "0.6.0" 

// If you want to use opencensus-scala inside a http4s project 
"com.github.sebruck" %% "opencensus-scala-http4s" % "0.6.0" 

// If you want to use opencensus-scala inside a elastic4s project 
"com.github.sebruck" %% "opencensus-scala-elastic4s" % "0.6.0" 

opencensus-scala uses typesafe config to configure exporters, sampling rates and many more. For a full reference have a look at the default configuration.

To activate the Stackdriver trace exporter with the default sampling rate of 1/10000 add the following to your application.conf.

opencensus-scala {
  trace {
    exporters {
      stackdriver {
        enabled = true 
        project-id = "MY-GC-Project"
      }
    }
  }
}
