Public Preview: Predictive Pooling for Standby Pools
May 15, 2025Public Preview: Zone Support for Standby Pools in Azure Container Instances
May 15, 2025
We’re excited to share that logging and monitoring capabilities are now available for standby pools in both Azure Virtual Machine Scale Sets (VMSS) and Azure Container Instances (ACI). This update brings greater visibility, operational confidence, and troubleshooting power to your standby infrastructure.
Why It Matters
Standby pools are designed to reduce scale-out latency by pre-provisioning compute resources. With the addition of logging and monitoring, you can now:
- Track pool health and readiness
- Audit provisioning and scale-out events
- Diagnose issues faster with integrated telemetry
- Set up alerts for degraded pool states or capacity shortfalls
These capabilities are powered by Azure Monitor and Log Analytics, giving you a centralized, queryable view of your standby pool activity across both Virtual Machine Scale Sets and Azure Container Instance environments.
What’s Included
For VMSS Standby Pools:
- Event logging for pool lifecycle operations (creation, updates, deletions).
- Health state tracking including degraded mode detection.
- Integration with Azure Monitor Logs for querying and alerting.
- Support for custom diagnostics and metrics via Azure Resource Graph.
For ACI Standby Pools:
- Container group-level logging with support for Log Analytics workspaces.
- Event data collection for container provisioning, reuse, and failures.
- Built-in support for Azure Monitor alerts and dashboards.
- CLI and API support for configuring logging during pool creation.
