Sources of monitoring data for Azure Monitor
Azure Monitor is based on a common monitoring data platform that includes Logs and Metrics. This platform allows data from multiple resources to be analyzed together using a common set of tools in Azure Monitor. Monitoring data may also be sent to other locations to support certain scenarios, and some resources may write to other locations before they can be collected into Logs or Metrics.
This article describes common sources of monitoring data collected by Azure Monitor in addition to the monitoring data created by Azure resources. Links are provided to detailed information on configuration required to collect this data to different locations.
Some of these data sources use the new data ingestion pipeline in Azure Monitor. This article will be updated as other data sources transition to this new data collection method.
Sources of monitoring data from Azure applications can be organized into tiers, the highest tiers being your application itself and the lower tiers being components of Azure platform. The method of accessing data from each tier varies. The application tiers are summarized in the table below, and the sources of monitoring data in each tier are presented in the following sections. See Monitoring data locations in Azure for a description of each data location and how you can access its data.
The following table briefly describes the application tiers that are specific to Azure. Following the link for further details on each in the sections below.
|Azure Tenant||Data about the operation of tenant-level Azure services, such as Azure Active Directory.||View Azure Active Directory data in portal or configure collection to Azure Monitor using a tenant diagnostic setting.|
|Azure subscription||Data related to the health and management of cross-resource services in your Azure subscription such as Resource Manager and Service Health.||View in portal or configure collection to Azure Monitor using a log profile.|

Azure Monitor Change Analysis
Change Analysis provides insights into your Azure application changes, increases observability, and reduces mean time to repair.
|Azure Resource Manager control plane changes||Change Analysis provides a historical record of how the Azure resources that host your application have changed over time, using Azure Resource Graph||Resources | Get Changes|
|Resource configurations and settings changes||Change Analysis securely queries and computes IP Configuration rules, TLS settings, and extension versions to provide more change details in the app.||Azure Resource Manager configuration changes|

Metrics and resource logs provide information about the internal operation of Azure resources. These are available for most Azure services, and monitoring solutions and insights collect additional data for particular services.
|Azure Monitor Metrics||Platform metrics will write to the Azure Monitor metrics database with no configuration. Access platform metrics from Metrics Explorer.||Getting started with Azure Metrics Explorer
Supported metrics with Azure Monitor
|Azure Monitor Logs||Copy platform metrics to Logs for trending and other analysis using Log Analytics.||Azure diagnostics direct to Log Analytics|

Resource logs provide insights into the internal operation of an Azure resource. Resource logs are created automatically, but you must create a diagnostic setting to specify a destination for them to be collected for each resource.
The configuration requirements and content of resource logs vary by resource type, and not all services yet create them. See Supported services, schemas, and categories for Azure resource logs for details on each service and links to detailed configuration procedures. If the service isn't listed in this article, then that service doesn't currently create resource logs.

|Storage||Send resource logs to Azure Storage for archiving.||Archive Azure resource logs|
|Event Hubs||Stream resource logs to other locations using Event Hubs.||Stream Azure resource logs to an event hub|
Operating system (guest)
Compute resources in Azure, in other clouds, and on-premises have a guest operating system to monitor. With the installation of an agent, you can gather telemetry from the guest into Azure Monitor to analyze it with the same monitoring tools as the Azure services themselves.
Azure Monitor agent
Install the Azure Monitor agent for comprehensive monitoring and management of your Windows or Linux virtual machines, scale sets and Arc-enabled servers. The Azure Monitor agent replaces the Log Analytics agent and Azure diagnostic extension.
|Azure Monitor Logs||The Azure Monitor agent allows you to collect logs from data sources that you configure using data collection rules or from monitoring solutions that provide additional insights into applications running on the machine. These can be sent to one or more Log Analytics workspaces.||Data sources and destinations|
|Azure Monitor Metrics (preview)||The Azure Monitor agent allows you to collect performance counters and send them to Azure Monitor metrics database||Data sources and destinations|
Log Analytics agent
Install the Log Analytics agent for comprehensive monitoring and management of your Windows or Linux virtual machines. The virtual machine can be running in Azure, another cloud, or on-premises. The Log Analytics agent is still supported but has been replaced by the Azure Monitor agent.
|Azure Monitor Logs||The Log Analytics agent connects to Azure Monitor either directly or through System Center Operations Manager and allows you to collect data from data sources that you configure or from monitoring solutions that provide additional insights into applications running on the virtual machine.||Agent data sources in Azure Monitor
Connect Operations Manager to Azure Monitor
Azure diagnostic extension
Enabling the Azure diagnostics extension for Azure Virtual machines allows you to collect logs and metrics from the guest operating system of Azure compute resources including Azure Cloud Service (classic) Web and Worker Roles, Virtual Machines, virtual machine scale sets, and Service Fabric.
|Storage||Azure diagnostics extension always writes to an Azure Storage account.||Install and configure Azure diagnostics extension (WAD)

|Application Insights Logs||Collect logs and performance counters from the compute resource supporting your application to be analyzed with other application data.||Send Cloud Service, Virtual Machine, or Service Fabric diagnostic data to Application Insights|
VM insights provides a customized monitoring experience for virtual machines providing features beyond core Azure Monitor functionality. It requires a Dependency Agent on Windows and Linux virtual machines that integrates with the Log Analytics agent to collect discovered data about processes running on the virtual machine and external process dependencies.
|Azure Monitor Logs||Stores data about processes and dependencies on the agent.||Using VM insights Map to understand application components|
Detailed application monitoring in Azure Monitor is done with Application Insights which collects data from applications running on a variety of platforms. The application can be running in Azure, another cloud, or on-premises.
When you enable Application Insights for an application by installing an instrumentation package, it collects metrics and logs related to the performance and operation of the application. Application Insights stores the data it collects in the same Azure Monitor data platform used by other data sources. It includes extensive tools for analyzing this data, but you can also analyze it with data from other sources using tools such as Metrics Explorer, Log Analytics, and Change Analysis.
|Azure Monitor Logs||Operational data about your application including page views, application requests, exceptions, and traces.||Analyze log data in Azure Monitor|
|Dependency information between application components to support Application Map and telemetry correlation.||Telemetry correlation in Application Insights
