Getting Started with MySQL Database Service — Lesson 4: Monitoring, Logs, Security, Cost, Troubleshooting, and Operations

Learning Objectives

• Explain the architecture, workflow, or business purpose behind metrics, alarms, events, logs, sessions, and resource health.
• Apply network, authentication, capacity, backup, and query troubleshooting and encryption, audit, patching, access reviews, and secure change in a controlled scenario.
• Validate outcomes and troubleshoot risks involving budgets, utilization, tags, runbooks, ownership, and improvement plan.

Detailed Topics

• metrics, alarms, events, logs, sessions, and resource health
• network, authentication, capacity, backup, and query troubleshooting
• encryption, audit, patching, access reviews, and secure change
• budgets, utilization, tags, runbooks, ownership, and improvement plan

Instructor Demonstration

Demonstrate metrics, alarms, events, logs, sessions, and resource health within a small application database migrated to OCI MySQL Database Service and prepared for reliable production use, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 4.

Hands-On Exercise

Implement a controlled exercise covering network, authentication, capacity, backup, and query troubleshooting and encryption, audit, patching, access reviews, and secure change, then introduce and resolve an exception involving budgets, utilization, tags, runbooks, ownership, and improvement plan while preserving before-and-after evidence.

1. Confirm the environment, identities, inputs, dependencies, risks, and expected outcome.
2. Complete the course-specific configuration, development, analysis, or process workflow.
3. Capture settings, commands, data, outputs, logs, reports, screenshots, calculations, or test results.
4. Compare the observed result with acceptance criteria and document corrective action.

Scenario Analysis

• Identify the technical or business decision that must be made.
• Compare valid approaches and their security, performance, reliability, cost, compliance, and support trade-offs.
• Define rollback, recovery, ownership, communication, and evidence requirements.

Troubleshooting Guidance

Diagnose issues across metrics, alarms, events, logs, sessions, and resource health, network, authentication, capacity, backup, and query troubleshooting, encryption, audit, patching, access reviews, and secure change, budgets, utilization, tags, runbooks, ownership, and improvement plan without making an unverified production change. Separate symptoms from causes, gather evidence, test the smallest reversible correction, rerun validation, and record preventive action.

Validation Checklist

• The requirement, scope, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by course-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply Monitoring, Logs, Security, Cost, Troubleshooting, and Operations in a realistic Getting Started with MySQL Database Service scenario and validate the result with documented evidence.
