SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill automates the process of analyzing container and system logs to identify errors, unusual patterns, and potential security threats, providing actionable insights without external dependencies.

Core Features & Use Cases

  • Error Extraction: Quickly identifies and lists error and warning messages from container logs.
  • Log Volume Analysis: Detects anomalies like "log storms" or silent services by analyzing log rates.
  • Security Event Scanning: Scans logs for patterns indicative of security breaches or suspicious activity.
  • Structured Reporting: Generates JSON reports for trend tracking and historical analysis.
  • Use Case: When a service becomes unresponsive, use this Skill to rapidly scan its logs for recent errors and assess the overall log volume to diagnose the issue.

Quick Start

Run the extract-errors.sh script to get a summary of errors from all containers in the last hour.

Frequently Asked Questions about log-analyzer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I analyze Docker container logs for errors and anomalies?▼

You can analyze Docker container logs for errors using shell scripts and Python to extract error messages, detect log volume anomalies, and scan for security events, generating structured JSON reports for root-cause analysis and trend tracking.

Can I scan container logs for security events in an air-gapped environment?▼

Yes, you can scan container logs for security events in air-gapped environments using local shell scripts and Python that operate without external dependencies, identifying suspicious activity patterns indicative of security breaches.

Do I need Docker installed to monitor system logs for real-time anomalies?▼

Yes, Docker must be installed and running to monitor system logs for real-time anomalies, as the Skill's shell scripts and Python tools depend on the Docker daemon to access container log streams.

What's the best way to detect log storms or silent services in container environments?▼

The best way to detect log storms or silent services is by analyzing log rates through the Skill's volume analysis feature, which identifies abnormal container log output patterns and flags services generating excessive or insufficient log activity.

How do I perform root-cause analysis on unresponsive containers using log data?▼

To perform root-cause analysis on unresponsive containers, scan recent logs with the error extraction script to identify error and warning messages, then assess overall log volume to correlate anomalies with the service failure.
