SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Diagnosing why Logstash is misbehaving (errors, latency, saturation, resource exhaustion, or unexpected restarts) by providing a structured triage workflow grounded in Netdata’s Logstash signals.

Core Features & Use Cases

  • Operator playbook-based diagnostic tree: Guides an AI coding agent to follow the same remediation logic used by the Netdata operator playbook, but with MCP queries to verify facts.
  • MCP-driven Logstash signal discovery and verification: Uses MCP to confirm the Logstash node exists, pull relevant logstash.* contexts over a window, and rank anomalies.
  • Remediation validation loop: Re-runs the same MCP queries after suggested remediation to ensure signals return to expected ranges.

Quick Start

Use the skill to troubleshoot an on-call incident by asking your AI: “Diagnose my Logstash problems using Netdata via MCP, verify the relevant logstash contexts, and recommend the safest remediation steps.”

Frequently Asked Questions about troubleshoot-logstash

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

FAQPage Schema
How do I troubleshoot Logstash operational issues like high latency or unexpected restarts?▼

To troubleshoot Logstash operational issues, you can use an AI agent to query Netdata via MCP for Logstash health signals and apply a diagnostic tree to validate metrics like elevated errors and resource exhaustion.

How does anomaly detection work for Logstash JVM metrics using Netdata?▼

Anomaly detection for Logstash JVM metrics works by querying Netdata via MCP to discover and rank anomalous `logstash.*` contexts, applying an operator playbook to correlate metrics within a defined time window.

What is the best way to triage Logstash saturation and resource exhaustion during an incident?▼

The best way to triage Logstash saturation is by following a structured diagnostic workflow that queries Netdata for JVM metrics, finds correlated anomalies, and recommends validated remediation steps.

Can I use MCP to verify Logstash remediation steps and validate that health signals return to normal?▼

Yes, you can use MCP to verify Logstash remediation by re-running the same query_metrics calls after suggested fixes to ensure health signals and JVM metrics return to their expected ranges.

Do I need Netdata to diagnose Logstash node errors and latency spikes?▼

Yes, diagnosing Logstash node errors and latency spikes with this workflow requires Netdata to provide the underlying JVM metrics and health signals accessed via MCP calls like list_nodes and find_anomalous_metrics.
