Understanding deployment options – Designing for Logging and Monitoring
By default, only Azure activity logs and platform metrics are enabled. Sending those logs to a Log Analytics workspace or enabling VM agents must be explicitly done. The VM agents are installed when you activate specific tools, such as VM insights, enabling guest-level monitoring, or enabling Logs in the Azure portal. As we see in …
