I see no data coming from 2 production servers (32-bit .NET 4.6.1 windows service app, 8.16.567.0 .net framework agent).
Last item in “nrdiag32.exe” output is a failure, but the page it refers to does not explain how to fix that.
Failure - DotNet/Profiler/InstrumentationPossible
Keys needed for .Net instrumentation are not set
See https://docs.newrelic.com/docs/agents/net-agent/troubleshooting/no-data-appears-net for more information.
Same application does report data when running in sandbox environment. But on that machine nrdiag32.exe skips InstrumentationPossible test
