Final answer:
To monitor virtual machines in Azure, use Azure Monitor, which provides comprehensive monitoring by collecting and analyzing telemetry. Azure Automation and Azure Security Center are supplementary services that provide automation and security functionalities.
Step-by-step explanation:
To ensure that your virtual machines (VMs) are running smoothly and without problems in Microsoft Azure, you can use the Azure Monitor service. Azure Monitor provides comprehensive monitoring of your Azure resources by collecting, analyzing, and acting on telemetry from both cloud and on-premises environments. It helps to maximize the performance and availability of your applications and proactively identify problems that may affect them.
Additionally, Azure Automation and Azure Security Center are services that offer more specific functionalities that can complement Azure Monitor. Azure Automation allows for the automation of common, repetitive tasks to maintain VM health, while Azure Security Center provides advanced threat protection and security health monitoring for your Azure resources.
