If you use On-premise version of Dynamics 365, monitoring performance of the local server is quite easy as the internal IT team has complete access to the application and DB servers. When it comes to Dynamics 365 online, users will not have option to login to the server and monitor the performance.
However, Microsoft has enabled 2 performance monitoring platforms to monitor the performance of the Dynamics 365 application as well as the custom apps in azure.
- Common Data Service analytics [Earlier known as Organization Insights]
- Application Insights
1. Common Data Service analytics [Earlier known as Organization Insights]
Microsoft has improved how you view metrics for your organization. You no longer need to install or update a solution. Instead, you can view Customer Data Service analytics right from the Power Platform Admin center to quickly view adoption ad user metrics for your organization. [ Earlier, a custom solution called Organization Insights needed to be installed to see this dashboard in CRM]
More details on this analytics platform are available here: https://docs.microsoft.com/en-us/power-platform/admin/analytics-common-data-service
2. Application Insights
To monitor your application, you add an Application Insights SDK to your application. The SDK sends telemetry to the Application Insights portal, where you can use our powerful analysis and diagnostic tools, or export the data to storage.
