Guest VMs on the HLH

Each Dell Integrated System SU comes configured with robust monitoring and alerting capabilities. The HLH has enabled the Hyper-V role to host several guest VMs, including those shown in the following table:

Guest VM	Description
Management VM	Hosting OpenManage Network Manager and Secure Connect Gateway for automatic support-case creation for hardware alerts.
OpenManage Enterprise	Monitoring and alerting of Dell PowerEdge servers: Compute and Storage health information and alerts Out of Band monitoring Provides health information for devices and components
Secure Connect Gateway	Provides automatic and manual system-state log collection Predictive issue-detection for failure prevention Automatic case-creation with Dell Technical Support Proactive contact from Dell Technical Support
OpenManage Network Manager	Networking health and alerts
Azure Stack Hub Administration Portal	Azure Stack Hub health and alerts Alerts generated from: Internal Health Services System Health Tests

Monitoring and alerting in scale unit nodes

The Health Resource Provider exposes the health and alerts for the Microsoft Azure Stack Hub software infrastructure components. The provider is viewable through the Azure Stack Hub Administration Portal or programmatically using REST APIs and PowerShell.

Hardware alerts

There is a limited number of hardware alerts that are exposed through the Health Resource Provider. However, it complements the greater level of monitoring detail that OpenManage Enterprise provides for server hardware components.

The server iDRACs poll for alerts and failures. Then they forward the events using Redfish protocol to Secure Connect Gateway for automatic ticket creation.

OpenManage Network Manager fulfills several critical functions in the Azure Stack Hub scale-node architecture, and uses SNMP and SYSLOG for switch monitoring. When hardware or configuration problems occur, OpenManage Network Manager generates alerts that are forwarded to OpenManage Enterprise for action. If required, an SR ticket is generated.

Other capabilities of OpenManage Network Manager are customer reports, performance monitoring, traffic-flow analysis, and firmware and compliance checking. These optional capabilities are not set up by default, but are available if needed. For instance, if you need a detailed report of the network switches, go to the Reports tab and create a detailed view of the switches, as shown in the following figure:

Software alerts

The Health Resource Provider manages the Azure Stack Hub software infrastructure component health and alerts. The Region Management monitoring tile in the Azure Stack Hub Administration Portal displays this information, as shown in the following figure:

Each alert displays details such as severity, state, created time, updated time, and description of the event, as shown in the following figure:

Prescriptive guidance on remediating each issue is provided through REST APIs and PowerShell.

External monitoring apps

The System Center Management Pack (SCOM) for Microsoft Azure Stack Hub enables you to monitor the availability of the Azure Stack Hub infrastructure. The management pack runs on a specified resource pool, and then uses various Azure Stack Hub APIs to remotely discover and collect instrumentation information, such as deployments, regions, and other resources.

For more information, see the Monitoring Integrated System for Microsoft Azure Stack with System Center Operations Manager White Paper.

For more information from Microsoft, see Management Pack for Microsoft Azure Stack now available.

Note: There are numerous external monitoring options, including Splunk, Nagios, and other monitoring platforms. SCOM and Nagios can both be integrated into Azure Stack Hub.
