Middleware for the Tesla HTTP client library that supports Datadog tracing using Spandex.
It creates a span for the client HTTP call, setting metadata:
[
http: [
status_code: status_code,
method: method,
url: url,
path: path,
query_string: URI.encode_query(query),
host: uri.host,
port: uri.port,
scheme: uri.scheme,
],
type: :web,
resource: "#{method} #{path}",
tags: [
span: [kind: "client"]
]
]See https://docs.datadoghq.com/tracing/trace_collection/tracing_naming_convention/
Add spandex_tesla to the list of dependencies in mix.exs:
def deps do
[
{:spandex_tesla, "~> 0.1.0"}
]
endAdd this middleware as a plug in your client.
