Could not get the metrics in the manager for standalone .Net applications

[saswin_d]

Hi Team/ @Anonymous 

I have tried Instrumenting  .Net standalone application with the help of the below reference link 

https://docs.appdynamics.com/display/PRO41/Instrument+Windows+Services+and+Standalone+Applications

I could load the profiler and was able to see the application under the "Tiers & Nodes" but was unable to get the transaction snapshots or metrics in the appdynamics controller.

I see the below error in the AgentLog.txt,

2022-02-10 08:41:24.0104 21836 AppDynamics.Coordinator 1 27 Error MachineAgentManager Metrics Error sending metrics - will requeue for later transmission Exception: com.appdynamics.ee.agent.commonservices.metricgeneration.metrics.MetricSendException: System.Exception: Failed to execute request to endpoint [https://****************.saas.appdynamics.com:443/controller/instance/76787/metrics_PB_].

Note: I can get metrics for the .Net applications deployed in the IIS 

Please look into this issue and help us to resolve this.

Thanks in advance

Hi @saswin.d,

Thanks for asking your question on the Community. That Documentation you linked to is very old. I don't know what version your Controller is on, but here is a newer version of that Document.

https://docs.appdynamics.com/22.2/en/application-monitoring/install-app-server-agents/net-agent/inst...

Note: In the upper right corner of the Docs page, you can adjust the documentation for the Controller version you are using. 

Please let me know if this helps you out.

Hi @Ryan.Paredez,

Thanks for the reply, I have checked with the version of the appdynamics agent which is the latest version(22.2).

I have followed the steps which have been mentioned in the document but still facing the same issue and couldn't find metrics in the manager as mentioned previously.

please look into this.

Thanks in advance.
