<?php // Example code to instrument a CNI plugin with OpenTelemetry use OpenTelemetry\API\Trace as APITrace; use OpenTelemetry\SDK\Trace\TracerProvider; use OpenTelemetry\SDK\Trace\Span; // Initialize OpenTelemetry Tracer $tracerProvider = TracerProvider::builder().build(); $tracer = $tracerProvider->getTracer('CNIInstrumentation'); function instrumentCNIAction($cniAction) { global $tracer; // Start a new span for the CNI action $span = $tracer->startSpan($cniAction); try { // Execute your CNI action logic here // For example, creating a network // ... } catch (\Exception $e) { $span->recordException($e); // Record exception if one occurs } finally { $span->end(); // End the span after the action completes } } // Call the function to instrument a sample CNI action instrumentCNIAction('create_network'); ?>
