Monitoring (Azure Monitor & Azure Service Health)

📝 For auditing, any interaction with Azure is recorded as Azure Activity Log

Azure Monitor

Solution for collecting, analyzing, and acting on telemetry from cloud and on-premises environments.
Helps you understand how your applications are performing and proactively identifies issues affecting them and the resources they depend on.
Aggregated view of different monitoring data
Increases availability and performance
Can be integrated with different services
- 📝 E.g. Azure Service Health to e.g. see if an issue is global.
Azure Monitor has its own features for visualizing monitoring data
- Also can send data different tools such as Dashboards, Views, Power BI

Application monitoring data
- About the performance and functionality of the code you have written, regardless of its platform.
Guest OS monitoring data
- Data about the operating system on which your application is running.
- This could be running in Azure, another cloud, or on-premises.
Azure resource monitoring data
- Data about the operation of an Azure resource.
Azure subscription monitoring data
- Data about the operation and management of an Azure subscription.
- Data about the health and operation of Azure itself.
Azure tenant monitoring data
- Data about the operation of tenant-level Azure services, such as Azure Active Directory.

Collected from e.g. virtual machines and web apps
Activity Logs record when resources are created or modified
Metrics tell you how the resource is performing and the resources that it’s consuming.
Some data types are: guest-level monitoring, performance counters, event logs, crash dumps, sinks, agents.

Monitors the performance of workloads in Kubernetes clusters in Azure Kubernetes Service (AKS).
Collecting memory and processor metrics from controllers, nodes, and containers
Container logs are also collected.

Monitors on-premises, or cloud VMs at scale
Analyzes the performance and health of Windows and Linux VMs
- also their different processes and interconnected dependencies on other resources & external processes.

Azure Monitor proactively notifies you of critical conditions using.
- e.g. sending a text or email to an administrator who is responsible for investigating an issue.
Alert rules based on metrics can provide alerts in almost real-time, based on numeric values.
Alert rules based on logs allow for complex logic across data, from multiple sources.

Uses Autoscale to ensure that you have the right amount of resources running to manage the load on your application effectively.
Enables you to create rules that use metrics from Azure Monitor, to determine when to scale
- Help reduce your Azure costs by removing resources that are not being used.
- You provide the logic that determines when Autoscale should increase or decrease resources.

📝 Comprehensive view of the health status of Azure
Notifies you about Azure services that affect you with impact & information.
- 📝 Can set-up automatic alerts
Guides you to prepare for planned maintenance & other changes that could affect the availability of your resources.
Consists of:
- Azure Status: Global view of the health state of all Azure services.
- Service Health: customizable dashboard that tracks the Azure services you’re using in the regions where you use them
  - Shows events such as ongoing service issues, upcoming planned maintenance, or relevant Health advisories
- Resource Health: helps you diagnose and obtain support when an Azure service issue affects your resources.
  - Personalized dashboard of your resources' health
  - Provides technical support to help you mitigate problems
  - Shows when you resources was unavailable because of Azure problems
    - Helps you to understand if an SLA was violated.
