SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires bash, jq, curl, systemctl, op, and includes references (resource) components.

What problem does it solve?

This Skill reduces time-to-detection for silent log-based failures by watching for missing OK markers and emitting Discord alerts when thresholds are exceeded.

Core Features & Use Cases

Missing START/OK detection: Detects cases where a log line contains a START marker without a matching OK line in a configurable time window.
Explicit error pattern scanning: Flags recent lines containing common failure keywords such as rejected, failed, Authentication failed, fatal, error, and timeout.
Anti-spam and auto-recovery: Suppresses repeated alerts for a cooling period and sends a green resolution message when the failures stop.
Discord webhook embedded reporting: Sends structured Discord embeds with consistent fields, colors, and a truncation-safe technical details section.
Operational suitability for cron polling: Designed to work with cron-based polling patterns and supports a state JSON file persisted across runs.

Quick Start

Use the log-monitor-discord-alert skill to monitor a cron-driven log file for START/OK mismatches and receive Discord alerts when failures accumulate past the configured threshold.

FAQPage Schema

How do I monitor cron log files for missing OK confirmations and detect silent failures?▼

You can monitor cron log files for silent failures by correlating START entries with missing OK confirmations within a configurable time window, triggering alerts when mismatches accumulate past a defined threshold.

Can I send bash log failure alerts to a Discord channel using webhooks?▼

Yes, you can send bash log failure alerts to Discord using webhook notifications, which deliver structured embeds with consistent fields, colors, and truncation-safe technical details directly to your channel.

How does anti-spam throttling work for Discord alerts triggered by recurring log errors?▼

Anti-spam throttling for Discord alerts works by suppressing repeated notifications during a cooling period using persisted JSON state, and automatically sends a green resolution message when failures stop.

What is the best way to scan systemd service logs for explicit error keywords like failed and timeout?▼

The best way to scan systemd service logs for explicit error keywords is using deterministic log parsing that flags recent lines containing terms like failed, fatal, error, and timeout within a specified time window.

Does this log monitoring approach support safe execution when run as a cron job?▼

Yes, this log monitoring approach supports safe cron-friendly execution by using a state JSON file persisted across runs, ensuring reliable polling without duplicate alerts or state corruption.

Do I need jq and curl to parse logs and send Discord webhook notifications?▼

Yes, you need jq for deterministic JSON log parsing and state management, and curl for sending webhook-based Discord embed alerts with truncation-safe payloads.
