What is the primary function of Azure Monitor?

The primary function of Azure Monitor is to collect and analyze logs and metrics. This service provides a comprehensive platform for monitoring the performance and health of your Azure resources and applications. By gathering data from various sources, Azure Monitor enables users to gain insights into system performance, diagnose issues, and understand the operations of their applications.

This capability is vital as it allows organizations to proactively identify performance bottlenecks and understand user behavior through detailed analytics. With Azure Monitor, users can set up alerts based on specific conditions and visualize metrics through dashboards, facilitating better decision-making and resource management.

The other options, while related to different Azure services, do not directly pertain to the core functionalities of Azure Monitor. For instance, managing user access is typically the role of Azure Active Directory, deploying applications falls under Azure DevOps or Azure Resource Manager, and securing data in transit is generally the responsibility of Azure's security and networking features.
