Virtual Machine Monitoring is the process of monitoring the individual virtual machines and VMs created in a virtualization environment. With VM monitoring tools you can view the availability status, performance stats and manage the VMs connected to the host and their corresponding guest virtual machines.
Despite the availability of a number of virtual machine monitoring tools in the market, only a few of them can monitor virtual environments holistically. OpManager's VM monitoring functionalities help monitor 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. With out-of-the-box reports, the option to set thresholds, fault and alarm management and performance monitors for virtual machines, OpManager provides comprehensive virtual server management for your VMware vSphere, Microsoft Hyper-V, or Citrix Xen host and associated virtual machines in real-time.
OpManager's virtual network management tool 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. Monitor the performance and availability of VMs with pre-configured performance monitors that help in monitoring various parameters. With OpManager's virtual server monitoring tools, 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 making monitoring virtual machines proactive; OpManager's VM monitoring tool raises alerts when the performance thresholds are violated helping identify faults for efficient troubleshooting. OpManager supports device templates that can be used to apply and associate monitors in bulk.
Today's hybrid networks have virtual machines from different hypervisors such as VMware ESX/ESXi servers, Hyper-V, Nutanix, Xen servers and more. Without a virtual machine monitor that is compatible to all hypervisors, network admins need to toggle multiple tools or tabs and lacks a centralized view on their critical metrics.
With OpManager's centralized dashboard for entire virtual environment, network admins can keep a track of VMware vSphere, Microsoft Hyper-V, or Citrix Xen host, and associated virtual machines in a single pane of glass. You can choose to have a separate view for individual hypervisors on their critical prformance metrics such as Top VMs by Memory utilization, Top VMs by CPU utilization, Top VMs by Disk I/O usage, Top hosts by Network usage. The VM sprawl dashboard features Top under, over-alocated VMs, idle VMs by CPU/ Memory utilization.
"VM sprawl: 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".
Optimize resources with VM monitoring tools
Resources are the crucial part in ensuring smooth functioning of virtual machines. Keeping the resources accessible to any virtual machine at the given point of time is necessary to ensure VM availability and performance. This requires managing VM sprawl, since idle, under or over-allocated VMs consume abnormal resources that creates excessive workload in the virtual environment. OpManager's dedicated VM sprawl dashboard features all those VMs so that network admins can easily get a glimpse of devices causing VM sprawl and reallocate resources to active VMs that actually need them. For instance, with the list "Top VMs by CPU over-allocated", network admins can identify which virtual machine is consuming more CPU resources and re-allocate to needy devices.
Perform effective capacity planning with VM monitor
OpManager's real-time monitoring of critical performance metrics such as CPU usage,memory usage and storage helps alert you instantly when the CPU usage shoots up or when the memory becomes low. Deciding whether to upgrade or purchase VM resources comes down to proper capacity planning.
OpManager's virtual machine monitoring 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. Leverage OpManager`s reports to analyze the growth patterns of critical metrics like CPU, memory, and storage of VM devices to determine if it`s a false spike or nearing its maximum capacity. This helps you make an informed decision, and prevent indiscriminate storage purchases.
To get a better visual understanding of your VM hosts and the related virtual machines associated with the host, OpManager's virtual machine monitoring 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's VM monitor also offers VM migration tracking that helps administrators migrate virtual machines from one physical host to another.
Monitor virtual machines 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. With Workflows, you can automate and execute certain actions based on the configured trigger profile for the related faults. This helps initiate better fault management activities and automates task that longer require manual intervention.
A virtual machine monitor helps in the 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.
Virtual machine monitor is used to collect data about the availability, and performance of virtual machines such as VMware, Hyper-V, and Xen, that is required to perform quicker fault resolution. Virtual machine monitoring hence helps ensure maximal uptime, manage resources, and thwart VM sprawl.
Virtual machine monitoring can be performed with the help of comprehensive VM monitoring solution such as ManageEngine OpManager. With threshold-based monitoring, OpManager proactively monitors virtual devices in real-time and notifies instantly on threshold breaches, thereby preventing unforessen network downtime and business losses.
