Investigate a policy remediation task that did not run Document and test manual replay of failed messages Resolve a Terraform state lock without losing deployment history Find gaps between enabled Defender plans and protected resources Check kernel changes after a Linux guest update Plan an integration that can recover after an outage Investigate an assessment with incomplete server data Investigate disk latency before resizing a virtual machine Validate a cluster after a network or storage change Choose NAT Gateway when stable outbound connectivity matters 
Check entity mapping when related alerts remain separate Check permissions when a security plugin cannot retrieve data 
Investigate an unexpected Conditional Access result Investigate a CodeQL alert before merging a pull request Investigate a virtual switch after a host network change Investigate a server update that repeatedly fails Investigate a scheduled script that works interactively Check hidden dependencies after an application failover Investigate throttling before changing a Storage account design Investigate a private endpoint that resolves to a public address 
Investigate a workflow trigger that fires unexpectedly Investigate failed node startup in an Azure Batch pool 
Trace a request through application and platform logs Keep an analyst review step in a repeatable promptbook Review Linux guest shutdown during host maintenance Use PowerShell Direct for Windows guest administration Investigate a live migration that stalls during maintenance Check a failed runbook using its job evidence Diagnose a VM boot problem using serial console evidence Ask focused questions about an identity-related incident Investigate slow disk access in a Linux VM 
Apply diagnostic settings consistently across Azure resources Troubleshoot deployment permissions without assigning Owner Use Copilot for Security alongside Defender investigations Check storage and network drivers in a Linux guest Review cluster event logs during a node failure Investigate a time synchronisation problem on Windows Server 
Trace a failed request through an API Management policy Review agent logs when an Arc extension fails Investigate a rule that creates too many incidents Troubleshoot a managed identity that cannot reach a resource Investigate a checkpoint chain before deleting files Check native command exit codes in an automation script Check DNS when a private file share is unreachable Investigate asymmetric routing through an Azure firewall Investigate an answer that lacks the expected security context 
Investigate agentless vulnerability findings before remediation Investigate a cluster validation report before dismissing warnings Read and validate JSON configuration in PowerShell Investigate a failover that leaves an application unavailable Investigate an alert that repeatedly closes and reopens Investigate a VM that cannot complete provisioning Investigate a function timeout without changing every setting Investigate a Linux guest that enters an emergency shell Test a planned failover and record the application result Check DNS configuration before investigating a domain problem Check connectivity with Azure Network Watcher Investigate an HPC job waiting for compute capacity 
Add a health check before enabling application scale-out Use promptbooks for repeatable security investigations Investigate a VM that cannot boot from installation media Add structured logging to an infrastructure script Plan private DNS zones before adding private endpoints Investigate a deployment that failed after creating some resources Investigate an Arc-enabled server that appears disconnected 
Investigate a failed sign-in using Entra logs Check time synchronisation in a Linux VM Configure a virtual network adapter and VLAN Investigate a cluster resource that keeps moving between nodes Investigate a Windows service that fails after a restart Investigate a module that loads in one shell but not another Investigate messages in a Service Bus dead-letter queue Plan shared storage access for an Azure HPC cluster Investigate a Linux guest with a missing network adapter Investigate a storage request that returns an authorisation error Investigate a server that stopped sending logs Diagnose a route that sends traffic to the wrong next hop Check Azure quota before a compute deployment fails Troubleshoot an application that fails to start in App Service Troubleshoot a Sentinel connector that stopped sending data Replace a service principal secret with workload identity federation Trace a blocked outbound connection in Azure Firewall logs Handle script failures using try, catch and ErrorAction What Copilot for Security can help a security team investigate Configure Secure Boot for a supported Linux guest
