Add IIS logs Application Insights
Allow App Insights to capture the IIS logs from the webservers. This would be very helpful when debugging on prem servers.
Recommendation is to ingest IIS logs into Log Analytics for efficient processing. When you ingest logs into Application Insights , each log entry gets a lot of extra dimensions and size of the logs blow up. Application logs can be ingested into Application Insights as part of distributed tracing stack, since they can be sampled as any other data in distributed tracing events.
Hope the above information helps, however if you have any further feedback please revert back and we are happy to hear from you more. Thank you
It would be nice if it supported onprem apps as well, not just WAD
