OpenCensus Receiver
Receives data via gRPC or HTTP using OpenCensus format.
Supported pipeline types: traces, metrics
Getting Started
All that is required to enable the OpenCensus receiver is to include it in the receiver definitions.
receivers:
opencensus:
The following settings are configurable:
endpoint
(default = 0.0.0.0:55678): host:port to which the receiver is going to receive data. The valid syntax is described at https://github.com/grpc/grpc/blob/master/doc/naming.md.
Advanced Configuration
Several helper files are leveraged to provide additional capabilities automatically:
Writing with HTTP/JSON
The OpenCensus receiver can receive trace export calls via HTTP/JSON in addition to gRPC. The HTTP/JSON address is the same as gRPC as the protocol is recognized and processed accordingly.
To write traces with HTTP/JSON, POST
to [address]/v1/trace
. The JSON message
format parallels the gRPC protobuf format, see this
OpenApi spec for it.
The HTTP/JSON endpoint can also optionally configure
CORS, which is enabled by
specifying a list of allowed CORS origins in the cors_allowed_origins
field:
receivers:
opencensus:
cors_allowed_origins:
- http://test.com
# Origins can have wildcards with *, use * by itself to match any origin.
- https://*.example.com

See github.com/rs/cors // An empty list means that CORS is not enabled at all. A wildcard (*) can be // used to match any origin or one or more characters of an origin. CorsOrigins []string `mapstructure:"cors_allowed_origins"` }
Config defines configuration for OpenCensus receiver.
