Hyper-V Virtual Machines
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.
- Availability tab lists all the virtual machines present in the Hyper-V servers and their availability status. You can also view the Availability history of the virtual machines for the past 24 hours or 30 days.
- Performance tab shows some key performance indicators of the virtual machine including CPU Utilization, Memory Utilization, Disk I/O Utilization and Network Utilization along with heat charts for these attributes. This tab also shows the health status and events for the past 24 hours or 30 days.
- List view displays all the virtual machines discovered under each Hyper-V server. This view provides an overall idea of the availability and health of all the virtual machines. The list view also enables you to perform bulk admin configurations. Click on the individual virtual machines listed to view detailed VM metrics.
- Top Virtual Machines tab shows graphs for the top CPU consumers, top memory consumers, top disk I/O consumers, and top network consumers of the Hyper-V server. This section enables you to find out which virtual machines are consuming your server resources and take action accordingly.
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
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.
