SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Helps you diagnose Postfix incidents by systematically locating the failing domain (availability, throughput, latency, errors, saturation, resource, and related internal state) using Netdata-observed signals.

Core Features & Use Cases

  • Operator-playbook-style triage: Routes an AI agent through an 8-domain diagnostic tree tailored to Postfix failure patterns.
  • MCP-driven Netdata verification: Uses MCP queries to list nodes, pull the right postfix contexts, and rank anomalies to decide what to investigate first.
  • Actionable remediation validation: Re-queries after suggested remediation to confirm signals return to expected bands, preventing “fix that didn’t stick.”
  • Use case: When Postfix shows degraded delivery behavior (elevated errors, latency, saturation, queue dwell issues, or unexpected restarts), this skill guides structured triage and validation against the same signals the Netdata operator playbook relies on.

Quick Start

Use the troubleshoot-postfix skill when a user reports Postfix performance or delivery issues and needs a structured, Netdata-backed triage plan with MCP queries to confirm findings and validate remediation.

FAQPage Schema
How do I troubleshoot Postfix mail delivery issues using Netdata signals?▼

Troubleshoot Postfix mail delivery issues by routing an AI agent through an 8-domain diagnostic tree covering availability, throughput, latency, errors, and saturation using Netdata-observed signals. MCP queries pull postfix contexts and rank anomalies to decide what to investigate first.

What is the best way to triage Postfix performance degradation during an incident?▼

Triage Postfix performance degradation using an operator-playbook-style diagnostic tree tailored to Postfix failure patterns. The structured approach locates the failing domain, maps outcomes to remediation guidance, and re-queries Netdata to validate that signals return to expected bands.

Can I use MCP queries to diagnose elevated Postfix queue dwell time and errors?▼

MCP queries can diagnose elevated Postfix queue dwell time and errors by listing nodes, pulling the relevant postfix contexts, and ranking anomalies. This structured triage identifies the failing domain and provides operator-playbook remediation guidance to resolve the issue.

How does Netdata verify that a Postfix remediation fix actually worked?▼

Netdata verifies Postfix remediation by re-querying the same signals after suggested fixes to confirm metrics return to expected bands. This action validation prevents a fix that didn’t stick by checking availability, throughput, latency, errors, and saturation domains post-remediation.

When do I need structured triage for Postfix unexpected restarts and saturation problems?▼

Structured triage for Postfix unexpected restarts and saturation is needed during on-call or incident-response workflows when engineers require systematic diagnosis across internal-state domains. It maps Netdata-observed anomalies to operator-playbook remediation guidance for targeted resolution.
