4	>
5	> This document is the official source for debugging and troubleshooting Azure production issues. Follow these instructions to diagnose and resolve common Azure service problems systematically.
6
7	## Triggers
8
9	Activate this skill when user wants to:
10	- Debug or troubleshoot production issues
11	- Diagnose errors in Azure services
12	- Analyze application logs or metrics
13	- Fix image pull, cold start, or health probe issues
14	- Investigate why Azure resources are failing
15	- Find root cause of application errors
16	- Troubleshoot App Service issues (high CPU, deployment failures, crashes, slow responses, TLS/custom domains)
17	- Respond to prompts like "troubleshoot app service", "app service high CPU", or "app service deployment failure"
18	- Troubleshoot Azure Function Apps (invocation failures, timeouts, binding errors)
19	- Find the App Insights or Log Analytics workspace linked to a Function App
20	- Troubleshoot AKS clusters, nodes, pods, ingress, or Kubernetes networking issues
21	- Troubleshoot Azure VM connectivity issues (RDP/SSH failures, port 3389/22 timeouts, NSG or firewall blocking, credential resets)
22	- Troubleshoot Azure Messaging SDK issues (Event Hubs, Service Bus connection failures, AMQP errors, message lock issues)
23
24	## Rules
25
26	1. Start with systematic diagnosis flow
27	2. Use AppLens (MCP) for AI-powered diagnostics when available
28	3. Check resource health before deep-diving into logs
29	4. Select appropriate troubleshooting guide based on service type
30	5. Document findings and attempted remediation steps
31	6. Route AKS incidents to the dedicated AKS troubleshooting document
32

34
35	## Quick Diagnosis Flow
36
37	1. Identify symptoms - What's failing?
38	2. Check resource health - Is Azure healthy?
39	3. Review logs - What do logs show?
40	4. Analyze metrics - Performance patterns?
41	5. Investigate recent changes - What changed?

60	- Keep Container Apps and Function Apps diagnostics in this parent skill.
61	- Route active AKS incidents, AKS-specific intake, evidence gathering, and remediation guidance to [AKS Troubleshooting](troubleshooting/aks/aks-troubleshooting.md).
62	- Route Azure VM RDP/SSH connectivity, NSG/firewall, credential reset, and VM agent troubleshooting to [VM Connectivity Troubleshooting](troubleshooting/compute/vm-troubleshooting.md).
63	- Route Azure Messaging SDK troubleshooting (Event Hubs, Service Bus) to [Messaging Troubleshooting](troubleshooting/messaging/README.md).
