Log Analytics collects data from managed resources and provides monitoring services for OMS.
The data include events, performance data, or custom data provided through the API. Then, add solutions that define data to be collected for its analysis and export. The method allows you to consolidate data from other sources to combine from your Azure services with your existing on premise environment.
There are ways to get data into the repository for Log Analytics to analyze. You can install the Microsoft Monitoring Agent on virtual machines, Linux and Windows computers. You can also connect the management group to Log Analytics if you have an existing Operations Manager environment and automatically start gathering data from current agents.
You can evaluate data from multiple sources in a single query, since data from all sources are stored as records and create your own custom views to analyze data and make it readily available in your custom portal.
