Symptom & Impact

Operational visibility is lost as system and app events stop reaching local or remote sinks.

Environment & Reproduction

Triggered by config edits, disk full conditions, or unreachable remote collectors.

Root Cause Analysis

Pipeline blockage or parser errors prevent message routing and file writes.

Quick Triage

Check disk space, daemon status, and rsyslog startup diagnostics first.

Step-by-Step Diagnosis

Validate rsyslog syntax and isolate broken include snippets or action modules.

Solution – Primary Fix

Correct invalid directives, reopen outputs, and restart rsyslog safely.

Solution – Alternative Approaches

Temporarily route critical logs via local file fallback until remote path recovers.

Verification & Acceptance Criteria

New events appear in expected files and remote collector receives forwarded streams.

Rollback Plan

Restore known-good rsyslog config bundle if changes break routing behavior.

Prevention & Hardening

Use config linting and canary logging checks before production rollout.

Related Errors & Cross-Refs

imuxsock errors, action suspended, and file permission denial warnings.
