The REST API in Azure Stack Hub provides a way to interact with Azure Stack resources and services over HTTP, enabling automation and integration with external monitoring tools. Through the API, users can query the system for various types of status information, perform health checks, and receive alerts about potential issues.
Azure Stack Hub includes a built-in Health Resource Provider, which is specifically designed for monitoring the health and wellness of the system. The Health API is part of the Admin Management API set and can be accessed using a REST client or any HTTP-compatible tool.
Using the API requires authenticating with Azure Stack Hub, typically using Azure Active Directory. Once authenticated, you can begin making requests to the API endpoints.
Some of the key endpoints related to system health monitoring include:
/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ResourceHealth/availabilityStatuses
: This endpoint provides availability status information for resources in a resource group./providers/Microsoft.AlertsManagement/alerts
: This endpoint allows access to alerts across the Azure Stack Hub environment.To get the health status of a specific resource using the REST API, you’d perform a GET request to the following endpoint:
GET https://management.local.azurestack.external/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ResourceHealth/availabilityStatuses?api-version=2015-01-01
To fetch active alerts that might indicate system issues, you use the following GET request:
GET https://management.local.azurestack.external/providers/Microsoft.AlertsManagement/alerts?alertState=active&api-version=2019-03-01
Responses from the REST API are typically in JSON format. For example, a health status response might contain the following data:
{
"id": "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ResourceHealth/availabilityStatuses/{availabilityStatusId}",
"name": "{availabilityStatusId}",
"type": "Microsoft.ResourceHealth/availabilityStatuses",
"location": "global",
"properties": {
"availabilityState": "Available",
"summary": "The resource is available and running smoothly.",
"detailedStatus": "Everything is operating normally.",
"reasonType": "Unplanned",
// Additional status details here
}
}
For more detailed metrics and log data, Azure Stack Hub provides APIs for working with metrics and logs as well. These APIs allow you to retrieve detailed performance and usage metrics, which can be used for deeper health analysis.
Once you’ve accessed the desired data using the REST API, you can integrate this data into external systems such as a SIEM (Security Information and Event Management) tool, or an ITSM (IT Service Management) solution. This enables comprehensive monitoring and alerting workflows that are in line with your organization’s operational practices.
The REST API is an essential tool for monitoring system health on Azure Stack Hub. By accessing endpoints related to health, alerts, metrics, and logs, IT professionals can retrieve critical information that aids in proactive system management and incident response. Furthermore, leveraging these APIs allows for integration with external monitoring systems, offering a complete monitoring solution tailored to the unique needs of a hybrid cloud environment managed through the Microsoft Azure Stack Hub.
