SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps you quickly diagnose network connectivity, latency, and outage incidents by analyzing heterogeneous device logs and correlating events across timezones to produce a structured incident report.

Core Features & Use Cases

  • Multi-format log parsing: Ingests Cisco IOS/NX-OS, Juniper JunOS, Palo Alto, F5 BIG-IP, RFC3164 syslog, and JSON-structured logs from file paths.
  • Timezone normalization & correlation: Normalizes timestamps to UTC, clusters related events across devices within configurable time windows, and builds an incident timeline.
  • Anomaly detection & incident reporting: Detects connection failure spikes, interface flapping, and error-rate spikes, then generates root-cause hypotheses and remediation recommendations.
  • Use Case: If you receive router, firewall, and load balancer logs for a suspected outage window, you can automatically identify cascading failures (for example, BGP session loss preceding connection timeouts) and produce an executive summary for stakeholders.

Quick Start

Use the network-incident-analyzer script to analyze all log files in a directory for a specific incident window in your local timezone and write a complete incident report to an output folder.

FAQPage Schema
How do I correlate network logs across multiple timezones to find the root cause of an outage?

Correlate network logs across multiple timezones by normalizing timestamps to UTC, clustering cascading events within configurable time windows, and generating a root-cause report. This process ingests mixed log sources to build a unified incident timeline.

Can I analyze mixed log sources like Cisco IOS, Juniper JunOS, and Palo Alto together for incident response?

Yes, you can analyze mixed log sources together for incident response. The analysis ingests Cisco IOS, Juniper JunOS, Palo Alto, F5 BIG-IP, RFC3164 syslog, and JSON structured logs to detect anomaly patterns and identify connectivity issues.

How does anomaly detection work for identifying network latency problems and interface flapping?

Anomaly detection for network latency problems works by detecting connection failure spikes, interface flapping, and error-rate spikes across normalized log events. It clusters these cascading events to formulate root-cause hypotheses and remediation recommendations.

What is the best way to troubleshoot network incidents using syslog and JSON structured logs?

The best way to troubleshoot network incidents using syslog and JSON structured logs is to parse heterogeneous device logs, normalize timestamps to UTC, and cluster related events to automatically identify cascading failures like BGP session loss preceding connection timeouts.

Does network log analysis support generating incident reports for stakeholder executive summaries?

Yes, network log analysis supports generating incident reports for stakeholder executive summaries. It outputs complete incident JSON and Markdown root-cause reports detailing connectivity issues, latency problems, and outage remediation recommendations.

What are the limitations of analyzing network logs for cascading failure detection?

A limitation of analyzing network logs for cascading failure detection is the dependency on raw log file availability from target devices. Accurate anomaly detection requires correctly formatted RFC3164 syslog or JSON logs within the specified incident window.
