OpenStack SDK (openstacksdk) instrumentation for OpenTelemetry

OpenTelemetry OpenStack SDK Instrumentation

OpenStack SDK (openstacksdk) instrumentation for OpenTelemetry.

The OpenStack SDK reaches every service through an openstack.connection.Connection whose service proxies (conn.compute, conn.network, ...) subclass openstack.proxy.Proxy. Every REST call the SDK makes funnels through a single method, Proxy.request, no matter which resource method the application called.

This instrumentor wraps Proxy.request so each SDK REST call becomes a CLIENT span. On instrument() it:

• records one span per request, named {service_type} {HTTP method} (for example compute GET), falling back to the bare HTTP method when the proxy has no service type;
• sets the standard HTTP client attributes http.request.method, http.response.status_code, url.full, server.address and server.port (the fully resolved URL is read back from the response once keystoneauth has looked up the endpoint);
• adds openstack.service_type and openstack.region_name describing the proxy that issued the call;
• injects the active W3C trace context into the outgoing request headers, so a trace started in the SDK continues on the OpenStack service that handles the request (when that service is instrumented too).

Proxy.request defaults to raise_exc=False, so HTTP error statuses come back as ordinary responses rather than exceptions; the span status is set to ERROR for any status code >= 400, and transport-level failures are recorded as exceptions on the span.

Note: the span is created at the proxy layer, so keystoneauth's own token and version-discovery requests — which go straight through the session rather than a proxy — are not traced. Only genuine SDK service calls produce spans.

Usage

from opentelemetry.instrumentation.openstacksdk import (
    OpenStackSDKInstrumentor,
)

OpenStackSDKInstrumentor().instrument()

import openstack

conn = openstack.connect(cloud="mycloud")
list(conn.compute.servers())  # emits a "compute GET" client span

Pass a tracer_provider to instrument() to use a provider other than the global default.
