How do I monitor Azure Large Instances?

Azure Large Instances is an IaaS offering and Azure teams are actively monitoring Azure Large Instances infrastructure (network devices, storage appliances, server hardware, etc.). Customer alerts related to infrastructure are provided only via Azure portal’s Service Health.
Customers are highly recommended to set up Service Health alerts to get notified via their preferred communication channels when service issues, planned maintenance, or other changes happen around Azure Large Instances.

For more information, see Configure Azure Service Health Alerts


Microsoft is not responsible for integration with any other tooling or 3P agents. Customers are responsible for any additional third-party agents that they would like to install for logging and monitoring on Azure Large Instances infrastructure.

It’s also recommended to rerun Azure Large Instances GenIO test post third-party agents are installed to check for any performance variations.

How does Microsoft communicate unplanned issues?

Microsoft sends service health notification only through the Azure portal. We always recommend customers to configure alerts for service health notifications.

This monitoring and alerting mechanism is different than traditional mechanisms. It's recommended for customers to set up Service Health alerts to their preferred communication channels for service issues, planned maintenance, or other changes that occur around Azure Large Instances. Not setting this up could cause issues with your Azure Large Instances that might go undetected for a long time and cause downtime if not addressed at the right time.

Receive activity log alerts on Azure service notifications using Azure portal

Based on my business priority, can I request a change in the “Planned” maintenance schedule for Azure Large Instances - if I must?

Microsoft sends a health notification service for both planned and unplanned events. Ensure you configure health alerts for service health notifications. If due to any business dependency, you need to request a change in the planned maintenance schedule, the preferred way would be to create a service request. Planned maintenance doesn't include emergency fixes/patches required which can't be rescheduled.

You can get Help and support in the Azure portal. It's available from the Azure portal menu, the global header, or the resource menu for a service and create a Service Request. In the dropdown menu you can look for the Epic key word and then "Azure Large Instances" and select appropriate service type.
