**Kibana version** : **Elasticsearch version** : **APM Server version** : **APM Agent language and version** : 1.19.0 - dotnet **Browser version** : 108.0.5359.125 - chrome **Original install method (e.g. download page, yum, deb, from source, etc.) and version**: nuget **Fresh install or upgraded from other version?** fresh **Is there anything special in your setup?** no **Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**: Working in .net core locally I had an issue stated in #1724, the application would hang because of the CPU metrics not being captured. After some search on the forums and on github I found that I could add the PerfomanceCounter key and some CPU values and the service would work fine. After the v.1.16.0 update I stopped needing to add this values on the configuration at all. Now I'm working on .net framework 4.6.2 service and the problem appeared again. If I add the new DisableMetrics setting to disable the cpu metrics the service stops hanging. Was this not added to .Net framework? **Provide logs and/or server output (if relevant)**: where are apm logs being saved? ---

Hi Pedro, could you collect and attach agent logs (with log level `Trace`)? See here: [Troubleshooting | APM .NET Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/dotnet/current/troubleshooting.html) Thanks Wolfgang ---

Helllo Wolfgang, Here is the logs. ![log0](https://us1.discourse-cdn.com/elastic/original/3X/4/3/4368a523aa472661bd02fbc58d55dee9cbc9c465.png) ![log1](https://us1.discourse-cdn.com/elastic/original/3X/1/5/155e8203addcb89db20aeb03e342cd1d1141de2e.png) ![log2](https://us1.discourse-cdn.com/elastic/original/3X/2/b/2b7cc8a4f73921f20292411b4e31fd711a201678.png) ![log3](https://us1.discourse-cdn.com/elastic/original/3X/9/8/982a0d2a76bb2a7716b848259a78e30612414a74.png) To note that we have the ElasticModule on the Web.Config, but add in the Global.asax a filter to remove the swagger calls. On this last image we see that I called the endpoint and got Outcome=Unknown. After this no more logs from APM, but if I add the DisableMetrics everything works fine (locally), because on the server I don't need to add anything and works fine. ---
