[Microsoft Azure](https://coralogix.com/docs/integrations/azure/introduction-to-microsoft-azure/index.md) platform monitoring focuses on capturing [platform logs](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/platform-logs-overview) - **Microsoft Entra ID, Activity, and Resource logs** - from various components within your environment.

## Overview

Azure [platform logs](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/platform-logs-overview), automatically generated, provide detailed diagnostic and auditing information for Azure resources and the Azure platform they depend on. They are divided as follows:

- **Microsoft Entra ID** **logs**, which capture activity at the authentication layer
- **Azure Activity logs**, which capture activity at the subscription layer
- **Resource logs**, which capture activity at the resource layer

## **Microsoft Entra ID** Logs

**Microsoft Entra ID logs** (previously **Azure Active Directory logs**) capture all the actions performed against your Active Directory domain. This includes the history of sign-in activity and an audit trail of changes made in Azure AD for a particular tenant. This type of log is focused on the Authentication layer of Azure. Find out more [here](https://coralogix.com/docs/integrations/azure/microsoft-entra-id-logs/index.md).

## Activity Logs

**Activity logs** provide insight into the operations performed *on* each Azure resource in the subscription from the outside, known as the management plane. This can include the creation or deletion of resources or updates to existing services. There's a single activity log for each Azure subscription. Find out more [here](https://coralogix.com/docs/integrations/azure/azure-activity-logs/index.md).

## Resource Logs

**Resource logs** [previously referred to as diagnostic logs] capture resource-specific audit information, providing insight into operations performed within an Azure resource. This is known as the data plane. Examples include a connection made to a PostgreSQL server or when a Blob is created, read, or deleted from a storage account. The contents of resource logs vary according to the Azure service and resource type. Find out more [here](https://coralogix.com/docs/integrations/azure/azure-resource-logs/index.md).
