Hello Thanakorn Sirikulpan,
Welcome to MS Q&A Forum.
Based on the error message above, this Resource Group was created by Azure Monitor.
When you create an Azure Monitor workspace, by default a data collection rule and a data collection endpoint in the form
<azure-monitor-workspace-name>
will automatically be created in a resource group in the formMA_<azure-monitor-workspace-name>_<location>_managed
.
From what I know if you delete Azure Monitor Account Resource, it would delete this Managed Resource group from your subscription.
