Performance Checklist¶

Use this checklist when a VM is slow, saturated, intermittently timing out, or showing resource pressure.

Initial response flow¶

graph TD
    A[Performance symptom] --> B[Capture incident window]
    B --> C[Check CPU, memory, disk, network together]
    C --> D[Identify whether one resource dominates]
    D --> E[Check guest process evidence]
    E --> F[Open performance playbook]

Checklist¶

1. Capture start time, recent deployment/change, and affected workload.
2. Pull Azure Monitor metrics for CPU, disk, network, and if available guest memory.
3. Check whether the issue is global slowness, one saturated resource, or disk-specific throttling.
4. Collect guest evidence with Task Manager, perfmon, top, free -m, or iostat.
5. Check whether B-series credit depletion or VM-size caps are in scope.
6. Route to one canonical playbook before resizing blindly.
