Symptom & Impact

System latency or throughput degrades after provisioning despite sufficient hardware.

Environment & Reproduction

tuned is running with a profile that conflicts with workload characteristics.

Root Cause Analysis

Run: tuned-adm active and systemctl status tuned.

Quick Triage

Check if virtualization, database, or low-latency profile should be used for this host role.

Step-by-Step Diagnosis

Capture active tuned profile and related kernel parameter effects.

Solution – Primary Fix

Capture profile switch command and resulting active state.

Solution – Alternative Approaches

List profiles: tuned-adm list and select target profile for workload.

Verification & Acceptance Criteria

Apply profile: sudo tuned-adm profile throughput-performance.

Rollback Plan

Re-test application metrics after profile change and watch CPU governor behavior.

Prevention & Hardening

Confirm tuned-adm active matches desired profile and performance baseline improves.

Related Errors & Cross-Refs

Set role-specific tuned profiles in provisioning automation for consistent host tuning.
