Many customers have requested the ability to configure an Application Insights telemetry key in their Dynamics 365 CRM/CE instance and be able to view/report and query (using app insights querying) at least the following data. One can imagine with these data points they could leverage other azure technologies to self heal or remediate as well as alert upon an increase in exception types or other arbitrary and flexible conditions as well build out PowerBI usage reports and end user adoption:
Form load & browser rendering/processing times
request source geographical data
All plugin execution logs redirected to appinsights fail/success, etc (instead of the database) allowing for reporting, alerting, and complex querying
Other processing times such as bulk Deletion job results
async plugin execution
system job results being mirrored into app insights telemetry (including workflows, async plugins, etc)
With these events along with their requestid's and correlation id's customers and partners could report on end-to-end scenarios and figure out how a given async plugin, workflow, process fired which specific plugins, etc.
