As we aware that vSphere upgrades can be performed seamlessly without disturbing the production workloads running inside the virtual machines. Where does the real downtime starts during the vSphere Upgrades? Yes, You are right!!. Drivers provides smooth mouse operations, Improve sound, Graphic and performance of the virtual machine. Improves Screen resolution. In vSphere 5. However, this statement is Partially accurate and has caused some confusion with customers.
VMware Tools upgrades has always required an operating system reboot as new device drivers and kernel modules will not go into effect until the next reboot. In both case, you can continue to run your virtual machine in a partially upgraded state for a limited amount of time until your next maintenance window, but it is recommended that you reboot as soon as possible.
It depends. This enables you to build your own customized reports, apps, and alert rules. Veeam One is a paid product. However, there is a free version. Veeam One Free includes all of the virtual machine monitoring capabilities of the paid system.
There is no capacity limit on the free version of the system, which is rare in the industry. The free version also lacks charge tracking and billing features. Both the free and paid versions display alert notifications on screen. These can also be sent by email , but only paid users can customize alert conditions. Tenant tracking also makes this an excellent choice for service providers, both for cloud storage provision and for software-as-a-service.
If you think you would be better served by the full, paid Veeam One service, you can test it on a day free trial. Foglight is a system monitoring system that has versions for cloud monitoring and VM environment management. The system works with VMWare and Hyper-V , focusing on the information gathered at the vSwitch, combined with physical performance data from the server.
The system sets itself up through an autodiscovery function. It identifies servers and their client virtual machines, and it examines the traffic that passes between them to highlight network performance. The traffic analysis data gathering section of this tool examines packet-level data to identify which VMs and applications generate the most traffic. The application monitoring dashboard gives you a display of all the elements in the Citrix VDI stack , highlighting strained infrastructure that could impact performance delivery.
The system cleverly maps the topology of your virtual environment to help visualize the locations of each VM and monitor the physical traffic flows between servers and VMs. The monitor extends into management functions as well. You can set it to dynamically adjust resources allocated to each application or VM to account for underutilization or over-capacity in different areas of the network.
The monitor dashboard gives you a range of views on Citrix user session activity from overall VM count summaries through to application activity. The Foglight monitoring system closely tracks NetScaler performance and network latency. The load on physical devices and virtual switches are other considerations. The Foglight monitor identifies inactive VMs and lets you remove zombie processes to free up resources.
This is an excellent feature because, unfortunately, the VM environment is prone to hanging processes and abandoned sessions that leave locks on resource allocations behind. The Foglight system explores and stores data to build up a testbed. The dashboard will show trend and variant performance and isolate data for each hardware element of your system.
This helps discover bottlenecks and resource misallocation. The data patterns and regular usage statistics give you a capacity planning function. With this tool, you can identify where to adjust the allocation of resources to improve performance and work out the effects of increased demand.
The Foglight monitor includes predictive capabilities that suggest actions to resolve alert conditions. This will also work with live data to help adjust network utilization on the fly. If you operate a multi-vendor environment with both VMWare and Hyper-V software operating onsite, you can unify your monitoring and management tasks in one place with the Foglight system. The monitor extends to cloud storage, so you can vary capacity by adjusting extra offsite provisions, such as additional storage.
Quest Foglight is not free. However, you can access a free trial to get a feel for the system. Foglight runs on Windows , Linux , and Solaris operating systems. You also need to see issues that arise on the network, on the storage server, in the database, or within the virtualization platform software. The interface for the system is browser-based. It includes graphical displays, lists of live data and alerts, and sections to assist with capacity planning.
The links between resources are mapped in the dashboard when you install the system. Examples of these relationships include application and VM platform interaction and the underlying physical infrastructure needs of the VM software.
That baseline informs the rule base of eG Enterprise on alert conditions that impair the performance of the environment. Not only will you receive alerts that the response times of a particular VM is slow, for example; you will be notified if the database is overloaded and whether that is causing a particular VM to perform poorly.
The ability to identify the root cause of performance issues at the lowest levels gives eG Enterprise its power. Multi-vendor environments are common and eG Enterprise unifies the monitoring of the provision stack for a wide range of possible combinations of virtualization systems. So, you will see each of the platforms individually, but the underlying resources that support several environments are monitored for total demand, not on a platform-by-platform basis.
The benefit of the unified stack approach is that it lets you see which VM hogs resources and makes the going tough for the rest of the network. The dashboard includes a great color-coded stack diagram that shows the coexistence of platforms at the supporting levels. EG calls this its in-n-out monitoring. Another nice visualization feature of eG Enterprise is a workflow-style diagram that traces all of the resources needed by a virtual machine and, in turn, the resources that each supporting feature requires.
Each element in the chain shows its status. So, if one of those nodes shows an alert, then you know exactly where to go to get that VM back in good health. The VM monitoring market is crowded with some very powerful tools provided by some huge software houses.
The eG Enterprise package has some handy features that the big guys lack. So, this little guy packs a punch and deserves its place among the top providers of VM monitoring systems. Aptare Virtualization Manager focuses on the storage servers that operate in virtualized environments.
This tool will monitor storage usage in your virtual network and report which VMs are using up capacity. The interface for the Aptare Virtualization Manager includes a planning tool. This tool can predict storage capacity needs based on historical data. The monitor also keeps track of VM access to storage and identifies potential bottlenecks and access contention.
Management functions extend to the identification of rogue processes that lock up storage allocations. You can use this performance management tool to free up space allocated to hanging processes, making it available to the other VMs in the environment. Monitoring VM environments is complicated.
You need to check on both infrastructure and software and monitor every element constantly in order to prevent performance impairment. Progress WhatsUp Gold covers all of the angles that you need to watch in order to successfully maintain virtualization. The core WhatsUp Gold software implements network performance monitoring, keeping an eye on the devices that connect your network links together.
However, there is a lot more that needs to be tracked to keep your VM system up and running. The Virtualization Monitoring add-on will cover those extra tasks. A vital feature of the add-on is an extension of the network discovery function of WhatsUp Gold. This will apply to all VM components the processes of mapping connections and dependencies that the main package applies to network devices. The system check gives WhatsUp Gold a baseline and from that, the add-on builds a map that shows the application stack that supports each VM.
You will be able to see which servers support which VMs and the status of server attributes and virtualization server software. As your VM system proceeds into normal operations, the add-on will continue to monitor performance, looking out for potential failure in software, servers, and the network.
Data collected by WhatsUp Gold is shown in real-time in the dashboard and it also gets saved as source information for analysis functions. With those planning tools you can work out whether any of your servers are overloaded and take appropriate action. Whichever way you choose to acquire WhatsUp Gold and the Virtualization Monitoring add-on, you can get them on a day free trial before you commit to buy.
Also, you need to have the VMWare software installed and operating to use this monitoring tool. However, it would be suitable for small-business virtualization implementations and lab scenarios. The tool offers an enhanced interface to your ESXi clients.
You can set up new VMs through this utility and configure the hosting for each. The monitoring aspect of the tool gives you insight into host statuses.
It will also list live data on events occurring in the VM environment. This is a simple tool, but the fact that it is free and that it comes directly from VMWare will tempt you to install it. The growth of the cloud in the provision of virtual environments can be seen by the product presentation of Turbonomic. Until recently, VM products prioritized on-site resources and then maybe dealt with Cloud-based services.
Oh, and by the way, it can also watch any onsite VM servers you might have. This very comprehensive VM performance monitoring tool for virtual environments comes in three packages: Essentials, Advance, and Premier.
Although this monitoring software is not free, you can get a day free trial of the Premier package. Pricing is based on the number of workloads that the monitor covers. The Essentials package has a limit of workloads, but the other two editions have unlimited capacity.
The monitor integrates controlling mechanisms and integrates AI into its action recommendation processes. You get more automation with the higher plans, but all editions include capacity planning capabilities. The setup process is automated and finishes with a system health check. This scan by the Turbonomic engine maps all of your virtual environment.
It finishes its onboarding with a list of recommendations on where your system problems lie and how you should resolve them. Once that initial phase completes, Turbonomic continuously monitors the environment, producing alerts on the dashboard, backing them up with action recommendations.
You can set an action rule base in the higher editions of Turbonomic to automatically perform resolution when specific alerts arise.
That automation is optional and you can launch recommended actions manually, or ignore them if you wish. This is a good tool for departments or services that adhere to service level agreements. Those SLAs can be translated directly into the monitoring system as quality of service requirements.
You can set alert levels for aspects of service including response times for delivery and transaction throughput for billing. The monitor allows you to reallocate resources to different applications or user groups and highlights areas where an expansion of cloud resources is inevitable. On the flip side, the Turbonomic AI engine will show you where you have over-provisioned , allowing you to scale back online services and cut costs.
That capacity visualization also extends to planning functions. The interface provides a capacity testing section where you can preview the effects of extensions to the user base or the inclusion of new applications and services. This is a great planning tool for bidding processing because it will enable you to plan out your extra services more effectively.
The dashboard for the monitor is customizable and you can allocate different views and controls to members of your team. The ability to create a user interface that does not include any controls at all gives you the option of letting clients or directors access the system without risking damage to your VM setup. If your virtual environment is all Hyper-V, then read on. This is a good solution if you manage data for other companies because you can identify demand down to the tenant, examine the performance of each host, and track user activity.
The dashboard of this service is highly customizable, which allows you to create different user accounts with different access rights. This is another feature that appeals to businesses that host services. You can give a limited dashboard to customers and enable them to manage their own VM allocation. Other views can be given to team members at different levels of seniority in your own group, and it lets directors and other interested parties within your company see live views of performance data.
Customizable reports enhance the data sharing features of this package. This review has given you a wide range of VM monitoring tools to choose from. Which is the best for you? Your circumstances will dictate that. Some VM monitoring tools are really system-wide infrastructure management systems that feature great virtualization functions. Other tools in the list are just small utilities that enhance your view of VM data or improve just one aspect of VM performance.
VM tools provisioning is a very broad field. Paessler and ManageEngine also try to cater to all points in the market. Some of the small players offer fantastic products that are bound to appeal to the small- and middle-sized enterprises , but also offer capabilities that could help businesses with large and complicated virtualized networks.
As you will glean from the statements in this report, the network monitoring industry is in transition at the moment. Ten years ago, virtualization was in its infancy and cloud services were a new trend. Both concepts now dominate networked services. It is not impossible to predict that, very soon, cloud services and the virtualization technology that makes them possible will be the standard method of network provisioning. The complexities of on-site server and application management will be a thing of the past.

View previous topic :: View next topic. Can anyone help me with this? I just installed the VMware Tools package that is part of Fusion and at the end it asked if I wanted it to auto rebuild modules if needed. I said yes and then when it tried to do its thing it failed saying it could not find mkinitrd or update-initramfs.
