Applications Manager monitors the virtual machines configured in the Hyper-V server. It gives the ability to manage VMs (Start / Stop / Restart) from the Applications Manager web client in case of any performance problems. Applications Manager's Virtual Machine monitoring tool provides extensive metric data to monitor your virtual machine servers. The solution also tracks attributes related to processes, guest OS, event log, etc. at the VM level.
Click on the individual monitors listed in the Availability tab to view detailed performance metrics of the corresponding virtual machine. Below is an explanation of the metrics shown in these tabs:

Guest OS monitoring allows to monitor the Processes, Services, Event Logs(if windows VM) in a Virtual Machine monitor. To enable this for a VM monitor, Go to VM Monitor Details page -> Click Monitor Actions -> Click 'Configure OS' option. Provide the server credentials to connect with the OS. Once configured, under the Process / Services tab, the option to Add/Remove the process will be shown. By using this option, we can add process / services for monitoring.
