Azure Monitor

Azure Monitor helps you maximize the availability and performance of your applications and services. It delivers a comprehensive solution for collecting, analyzing, and acting on telemetry from your cloud and on-premises environments. This information helps you understand how your applications are performing and proactively identify issues affecting them and the resources they depend on.

Just a few examples of what you can do with Azure Monitor include:

• Detect and diagnose issues across applications and dependencies with Application Insights.
• Correlate infrastructure issues with VM insights and Container insights.
• Drill into your monitoring data with Log Analytics for troubleshooting and deep diagnostics.
• Support operations at scale with smart alerts and automated actions.
• Create visualizations with Azure dashboards and workbooks.
• Collect data from monitored resources using Azure Monitor Metrics.

Azure Monitor agent is the way to collect text and IIS files for Log Analytics. 

Today Microsoft is happy to introduce the long-awaited Custom Log and IIS Log collection capability. This new capability is designed to enable customers to collect their text-based logs generated in their service or application. Likewise, Internet Information Service (IIS) logs for a customers’ service can be collected and transferred into a Log Analytics Workspace table for analysis.  These new collection types will enable customers to migrate from other competing data collection services to Azure Monitor.
