Final answer:
Azure Monitor is a service in Microsoft Azure that collects telemetry data which includes performance metrics and logs from resources in Azure. This data is vital for monitoring, troubleshooting, and ensuring the health and performance of applications and services on the cloud platform.
Step-by-step explanation:
The terms Azure Monitor and Telemetry are intimately connected in the realm of cloud computing and analytics. Azure Monitor is a service provided by Microsoft's cloud platform, Azure, that provides comprehensive monitoring of applications, infrastructure, and network activity. It collects data in the form of telemetry, which refers to the process of recording and transmitting the readings of an instrument. In essence, telemetry within Azure refers to various metrics and logs that are automatically collected from resources running in Azure.
This telemetry data gathered by Azure Monitor can include a variety of performance metrics, event logs, and other signals that are vital for understanding the health and performance of applications and services. The telemetry collected doesn't just provide instantaneous snapshots of performance; it allows for long-term trending and analysis, which can help in troubleshooting, capacity planning, and ensuring application resilience.
Through Azure Monitor, IT administrators and developers can access the telemetry to gain insights into their application's operations. This could include identifying slow operations, checking for errors, ensuring compliance with policies, and much more. Azure Monitor provides a unified approach to collecting, analyzing, and acting on telemetry, enabling a proactive rather than reactive management strategy for Azure-hosted services.
