Hello, I am looking at a ,NET core CoreClR process, dynatrace is showing below: ![henk_stobbe_0-1713267679840.png](https://global.discourse-cdn.com/dynatrace/original/3X/c/a/ca3df67f408e6dc2e471efd7b91be8b49983a505.png) What could be the reason for this?

Hey [@henk\_stobbe](https://community.dynatrace.com/user/11427) Check your Custom Process Monitoring Rules. ![ChadTurner_0-1713268311293.png](https://global.discourse-cdn.com/dynatrace/original/2X/1/161290f4d0a07283e0f50cb3838e300e7df1d719.png) The built in rules have IDs and they are shown in that error statement typically. I would love to see Dynatrace add in some ID and reference to the rule(s) that is disabling/preventing deep monitoring. ---

Hi, You can read this in [Process deep monitoring](https://docs.dynatrace.com/docs/shortlink/process-group-monitoring): ![AntonPineiro_0-1713277001010.png](https://global.discourse-cdn.com/dynatrace/original/3X/0/e/0ef99d8f4efec1a8899f7932b3e4f22c33544dea.png) I would check that process and I will turn on deep monitoring or creating some custom process rules and [@ChadTurner](https://community.dynatrace.com/user/14877) is saying. Best regards ---

Hi [@henk\_stobbe](https://community.dynatrace.com/user/11427) , You have mentioned that the monitoring of this process is on, I think the deep monitoring is set to default and you can change it to monitor, then the message should be changed to restart the process ![Mohamed_Hamdy_0-1713293250062.png](https://global.discourse-cdn.com/dynatrace/original/3X/7/6/76b6da271eac18cb721befaa91de24768fb3221e.png) also, you need to be aware that enabling deep monitoring can cause an issue, so you can test it on stage/UAT or enable it on one process only. Regards, Mohamed ---
