APM tracks request flows using:

Using Trace ID (A): A unique identifier assigned to a trace (collection of spans) for a single user request. Propagated via HTTP headers, it links all spans across services.

Why not B or C?

User ID (B): Identifies users, not request flows.

Application Name (C): Too broad; doesn’t correlate specific requests.

Trace ID ensures end-to-end visibility in distributed systems.

The Database Management Service enhances database oversight:

Monitor database performance (B): Provides tools like Performance Hub to track real-time and historical metrics (e.g., CPU, I/O).

Perform management tasks across a group of databases (C): Database Fleet Management enables bulk operations (e.g., configuration checks, SQL execution) across multiple databases.

Why not A or D?

A: Log viewing is via Logging Service, not a core DM feature.

D: SQL analysis is in Operations Insights, not DM directly.

These capabilities streamline database administration.

In OCI Logging Service, Log Categories classify logs based on their origin or purpose.

Custom Logs (D): This is a valid Log Category for logs generated by user applications or services not natively integrated with OCI. Custom Logs are collected using agents, SDKs, or APIs and are user-defined.

Why not A, B, or C?

VCN Logs (A): Virtual Cloud Network (VCN) flow logs exist, but “VCN Logs” isn’t a formal Log Category; it’s a type of service log.

OCI Agent Logs (B): Agent logs are internal to Management Agents, not a user-facing Log Category.

System Logs (C): While system logs exist in some contexts, OCI Logging uses specific categories like “Audit Logs” or “Service Logs,” not a generic “System Logs.”

“Custom Logs” is explicitly supported for user-generated log data.

A reliable log monitoring environment filters signal from noise:

Noise baseline determination (B): Establishes the typical level of irrelevant log data, allowing filters (e.g., severity levels) to focus on meaningful events, improving monitoring effectiveness.

Why not A, C, or D?

A: ML models are advanced, not essential for baseline setup.

C: KPIs are useful but secondary to noise reduction.

D: Permissions are administrative, not core to reliability.

Noise baseline is foundational.

Management Agents collect and send data to OCI services:

Logging Analytics (B): Agents gather log data from various sources (e.g., files, databases)and send it to Logging Analytics for indexing and analysis.

Enterprise Manager (C): Agents integrate with Oracle Enterprise Manager, enabling monitoring of on-premises or cloud targets within OCI.

Why not A or D?

Application Performance Management (A): Uses Java and Browser Agents, not Management Agents.

Database Management (D): Leverages agents indirectly via other services, not a direct target.

These services leverage Management Agents for observability.
