Symptom & Impact

Operational and audit events are missing from expected log files, reducing observability and compliance confidence.

Environment & Reproduction

RHEL 8 with custom rsyslog rules; test logger messages do not reach target file path.

Root Cause Analysis

Rule ordering issues, syntax errors, incorrect file permissions, or SELinux context mismatch on log directory.

Quick Triage

Confirm service status with `systemctl status rsyslog` and run config validation before restarting.

Step-by-Step Diagnosis

Use `rsyslogd -N1`, inspect `/etc/rsyslog.d/*.conf`, check destination file labels, and review `journalctl -u rsyslog`.

Solution – Primary Fix

Correct rule syntax/order, create destination with proper ownership/context, restart rsyslog, and send test events.

Solution – Alternative Approaches

Forward logs to centralized collector via RELP or journald forwarding for reduced local rule complexity.

Verification & Acceptance Criteria

`logger` test lines appear in target file and rotation policies continue without data loss.

Rollback Plan

Restore previous rsyslog configuration backup and reload service if new route breaks ingest.

Prevention & Hardening

Validate rsyslog config in CI and monitor log pipeline liveness with synthetic events.

`error during parsing file`, missing file writes, and SELinux denials on `/var/log` subpaths.
