Overview

OpenCensus is a vendor-agnostic single distribution of libraries to provide metrics collection and tracing for your services. See https://opencensus.io/ for general information on OpenCensus.

The OpenCensus module provides a namespace for the Ruby implementation of OpenCensus, including the core libraries for OpenCensus metrics and tracing.

Class Method Details

.configure ⇒ Object

Configure OpenCensus. Most configuration parameters are defined in subconfigurations that live under this main configuration. See, for example, OpenCensus::Trace.configure.

If the OpenCensus Railtie is installed in a Rails application, the toplevel configuration object is also exposed as config.opencensus.

Generally, you should configure this once at process initialization, but it can be modified at any time.

Example:

OpenCensus.configure do |config|
  config.trace.default_sampler =
    OpenCensus::Trace::Samplers::RateLimiting.new
  config.trace.default_max_attributes = 16
end
