What is Azure Log Analytics?
Azure Log Analytics is a subset of the Azure Monitoring service. Log data collected by Azure Monitor is stored in a Log Analytics workspace, which is based on Azure Data Explorer. It collects telemetry from a variety of sources.

Many companies are already using Azure services; directly or indirectly. Directly is a workload like virtual server or appliance. Indirectly would be using Azure Directory Services while using Teams. In either case, there is already some level of experience with Azure. This includes Directory Synchronization and access delegation to service payments. Because of this adding Azure log services becomes a simple add-in. Azure Log Services can be used to monitor more than just Skype Room Systems. It can monitor all levels of a Windows-based system as well as syslog services and direct file analytics. It offers robust tools and query languages to develop reports on different types of logs.
