Operations Insights collects telemetry data for analysis from:

Management Agent (C): A lightweight process that gathers metrics (e.g., CPU, memory) from hosts, databases, or applications and sends them to Operations Insights.

Enterprise Manager (D): An on-premises tool that provides database performance and configuration data to Operations Insights.

Why not A or B?

OCI Streams (A): A streaming service, not a telemetry source for Operations Insights.

OCI Functions (B): Serverless compute, not a direct telemetry source.

These sources enable comprehensive resource monitoring.

FluentD is an open-source data collector used for continuous log collection with client-side processing in OCI Logging. Two applicable scenarios are:

Managing apps/services which push logs to Object Storage (A): FluentD can be configured to collect logs from applications or services (e.g., Oracle Functions) that write logs to Object Storage buckets. It processes these logs client-side and forwards them to OCI Logging or Logging Analytics.

Comprehensive monitoring for OKE/Kubernetes (B): FluentD is widely used in Kubernetes environments like Oracle Container Engine for Kubernetes (OKE) to collect logs from pods, containers, and nodes. It processes these logs locally before sending them to OCI services for analysis.

Why not C or D?

Monitoring unsupported systems (C): While possible, this is not a primary FluentD scenario in OCI—it’s more about extending Management Agent capabilities.

Log Source (D): This is a component of Logging Analytics, not a FluentD scenario.

FluentD’s flexibility makes it ideal for these use cases in OCI’s observability ecosystem.

In distributed tracing within OCI APM:

Root span (C): The first span in a trace, representing the entry point of a user request (e.g., an HTTP request from a browser). It has no parent span and initiates the chain of subsequent spans across services.

Why not A or B?

Ajax call (A): A type of request, not a span term.

Trace ID (B): A unique identifier for the entire trace, not a span.

The root span is foundational to tracing a request’s journey.
