Symptom & Impact

Latency and throughput deviate because intended tuned profile is not active.

Environment & Reproduction

Profile changed manually but not applied by service at boot.

tuned-adm active
systemctl status tuned

Root Cause Analysis

tuned daemon disabled, conflicting profile scripts, or unsupported profile selection.

Quick Triage

Check active profile and service enablement.

tuned-adm list
systemctl is-enabled tuned

Step-by-Step Diagnosis

Inspect tuned logs and profile configuration overrides.

journalctl -u tuned -n 200 --no-pager
cat /etc/tuned/active_profile

Solution – Primary Fix

Select correct profile and ensure tuned starts at boot.

tuned-adm profile throughput-performance
systemctl enable --now tuned

Solution – Alternative Approaches

Create custom derived profile for workload-specific tuning.

cp -a /usr/lib/tuned/throughput-performance /etc/tuned/custom-throughput

Verification & Acceptance Criteria

Active profile remains unchanged after reboot and benchmarks normalize.

reboot
tuned-adm active

Rollback Plan

Switch back to balanced profile if workload regressions appear.

tuned-adm profile balanced

Prevention & Hardening

Version-control tuned profiles and baseline benchmark outputs.

tuned-adm recommend
journalctl -u tuned -p warning -n 60 --no-pager

Related Errors & Cross-Refs

No active profile, tuned daemon not running.
