Your microservices-based applications use various tracing libraries (OpenTelemetry, OpenCensus, OpenTracing, Honeycomb, Jaeger). After implementing Application Insights in Azure Monitor, you want to centralize distributed tracing. Which two libraries can integrate directly with Application Insights?

OpenTelemetry and OpenCensus are the two libraries that integrate directly with Azure Application Insights for distributed tracing. Application Insights provides native support for ingesting telemetry data from both OpenTelemetry and OpenCensus SDKs, allowing you to centralize and visualize traces from services instrumented with these standards. Honeycomb and Jaeger are standalone distributed tracing systems that typically require custom exporters or bridges to send data to Application Insights, rather than direct integration. OpenTracing is an older specification, largely superseded by OpenTelemetry, and does not have direct integration with Application Insights without an OpenTelemetry bridge.
