Thanks for reaching here! You might be aware of that Azure Monitor collects and aggregates data from a variety of sources into a common data platform where it can be used for analysis, visualization, and alerting. It starts collecting data from Azure resources the moment they're created.
Monitoring solutions in Azure Monitor provide analysis of the operation of a particular Azure application or service. You may refer below document link which provides a brief overview of monitoring solutions in Azure and details on using and installing them.

You can add monitoring solutions to Azure Monitor for any applications and services that you use. They're typically available at no cost but collect data that could invoke usage charges.
Further you may check this quickstart which provides a brief walkthrough of the data that's automatically collected for a resource and how to view it in the Azure portal for a particular resource. Later, you can add configuration to collect additional data and can go to the Azure Monitor menu to use the same tools to access data collected for all the resources in your subscription.
For more detailed descriptions of monitoring data collected from Azure resources see Monitoring Azure resources with Azure Monitor.
