Virtual Machine Monitoring is the process of monitoring the individual virtual machines and VMs created in a virtualization environment. A virtual machine monitor software helps in the creation and management of VMs with separate operating systems and applications when installed over a host machine. It also handles the allocation of memory, storage and computing resources for the created VMs. With a virtual machine monitoring tool, you can view the availability status, performance stats and manage the VMs connected to the host and their corresponding guest virtual machines.
OpManager provides a comprehensive monitoring of VMware ESX/ESXi servers, HyperV, Xen servers and the related guest virtual machines. It provides detailed insights on the performance and health of the host servers. OpManager also ensures the peak performance of the ESX/ESXi servers and helps administrators extend the uptime of virtual servers with proactive monitoring. With out-of-the-box reports, the option to set thresholds, fault and alarm management and performance monitors for virtual machines, OpManager provides comprehensive monitoring for your VMware vSphere, Microsoft Hyper-V, or Citrix Xen host and associated virtual machines in real-time.
OpManager simplies the entire process of virtual machine performance monitoring. It automatically discovers, maps and monitors all the VMs in a host with just the server host-name and the required credentials. You can easily view the CPU allocated for each virtual machine and identify which virtual machine is consuming more CPU resources using OpManager.'s virtual machine monitors. Monitor the performance and availability of VMs with pre-configured performance monitors that help in monitoring various parameters. You can also drill down on specifics and identify the virtual servers running low on resources.
The 'Top Hosts' listing in OpManager lists the machines with high CPU consumption or Swap memory consumption. Some of the monitors available are CPU Wait/ Ready, Memory Balloon/ Shared/ Swapped/ Overhead, etc. You can also configure thresholds for the monitors which enable OpManager to proactively monitor VM resources and raise alerts when they go down or reach a critical level. OpManager supports device templates that can be used to apply and associate monitors in bulk.
With OpManager, you can tackle the major problem of memory allocation and prevent virtual machines from running out of memory. Get instantly notified when the memory usage shoots up or when the memory becomes low. Monitor parameters like free physical memory, page faults, page reads, page writes, pages per second, available page-file memory size, available physical memory and available virtual memory with the help of monitors which can be associated with the virtual machine.
Capacity planning for a large organization which spans over different geographical locations can be tedious. In a large scale organization, hundreds of VMs will be created to manage the server load. It is difficult to analyze and predict when the limit will be reached. Lack of resources can affect businesses and once VMs get accumulated, they will drain a considerable amount of resources. This will lead to a point where the administrator can no longer manage them effectively. This is called Virtual machine (VM) sprawl or virtualization sprawl. OpManager's advanced memory and availability monitoring capabilities provide critical insights on capacity planning and memory allocation and simplifies capacity planning.

To get a better visual understanding of your VM hosts and the related virtual machines associated with the host, OpManager provides real-time network topology maps. Spot virtual servers that need relocation and understand the relation between hosts and VMs, networks and data stores. OpManager also offers VM migration tracking that helps administrators migrate virtual machines from one physical host to another.
OpManager's fault management capabilities help you monitor your virtual machines on the go. Take charge of your virtual machine management on the go with instant notifications via SMS or email on performance hiccups, faults and downtime with OpManager. You can perform instant fault troubleshooting and remediation tasks on virtual machines using OpManager's advanced workflow automation feature. Automate and execute workflow actions based on the configured trigger profile for the related faults. OpManager also provides over a 100 out-of-the-box reports that help in identifying and analyzing utilization trends, performance, memory and network utilization for hosts and VMs. These reports can also be scheduled and sent as an email to the desired recipients.
