An Azure platform native monitoring solution that enables Azure monitoring across multiple tenants or subscriptions.
Problem statement: A service provider with 50 tenants, each with Azure subscriptions provisioned through CSP (Cloud Solution Provider), needs to consolidate operational telemetry to optimize running costs, as well as deliver higher SLAs with a minimum amount of administrative overhead.
Enter zMonitor, a platform for reporting based on Log Analytics data collected, quickly gaining insights across tenants or subscriptions. Gain insights on disks capacity status, VM performance - over or under utilized CPU/Memory/Disk/etc, security vulnerabilities - failed logons, update/patch status, application errors, etc.
The primary goal is to utilize Azure native components, and deliver an as simple as possible, highly configurable and scalable, cost-effective monitoring solution. The driving force behind this solution was the need to be able to monitor Azure resources across tenants (for service providers), using Azure native tools. While there are many metrics and logs generated in Azure, surfacing this information across subscriptions/tenants and effectively monitoring proved challenging. Design decisions focused on limiting Azure costs on the tenants/subscriptions components, and rather have the bulk of the costs incurred on the single central component (service provider).
For an indication of potential costs for the solution, review the cost estimate documentation.
For monitoring within subscriptions, OMS Log Analytics is leveraged as the native log and metric aggregation toolset in Azure. Using the free tier of Log Analytics will be sufficient for most cases, but depends on the number of resources being monitored and the metrics being collected.
Log Analytics data is then exported into a central Cosmos DB collection, from where it can be vizualized using any preferred tool. For this solution, PowerBI is used for demonstration purposes.
The components that make up the solution:
-
Tenant / Subscription
- Log Analytics
- Azure Automation
-
Service Provider / Central Repository
- Azure Storage Account (BLOB)
- Stream Analytics
- Azure Cosmos DB
- Azure Automation
- [Optional] Power BI
