 ## Overview: Monitor VM host and guest metrics and logs
 
-You can collect metrics and logs from the **VM host**, which is the physical server and hypervisor that creates and manages the VM, and from the **VM guest**, which includes the operating system and applications that run inside the machine.
+You can collect metrics and logs from the **VM host**, which is the physical server and hypervisor that creates and manages the VM, and from the **VM guest**, which includes the operating system and applications that run inside the VM.
 
 VM host and guest data is useful in different scenarios:
