Citrix: professional and high-performance virtualization

Virtualization is a crucial component of many firms’ IT environments. Citrix XenServer is a professional virtualization platform that boasts an extremely high level of performance. Citrix XenApp and XenDesktop provide these virtual servers with Windows apps and desktops for a variety of end devices.

With Citrix performance monitoring, you’ll not only ensure the performance of your virtual machines always remains high, but you’ll also avoid downtime.


Advantages of Citrix monitoring

Maintain a constant overview

Maintain a constant overview

When it comes to virtualization with Citrix XenServer, you should always have an overview of the key parameters. PRTG displays all the important data of your Citrix virtualization on easy-to-read dashboards. You'll immediately see if your hardware, hypervisor, and software are running smoothly or if any update or patch is available. With PRTG Citrix monitoring, you'll keep a constant eye on potential trouble spots.


Be promptly informed of malfunctions

Be promptly informed of malfunctions

In critical situations such as server failure or resource overload, it is vital that action is taken quickly. PRTG informs you by way of custom notifications whenever your Citrix environment fails to run the way it should. Let’s say you set your CPU load threshold value at 70%. Should the CPU exceed this level, you’ll automatically receive a notification from PRTG by email, by SMS, or by way of the app. The same goes for all the other values you assign.

You can therefore intervene quickly - before, for example, the host server reaches its load limit and your customers and coworkers can tell that something is up. Instead of complaining, the latter will thank you for ensuring that all the virtual machines are running smoothly and efficiently, and that they can continue working without interruption.



Optimize your resources with Citrix monitoring

With Citrix server monitoring, you can quickly determine which host servers are under the greatest strain, and which ones are not being used to capacity. A highly-strained server affects the performance of all the virtual machines running on it. By distributing the load equally, you will not only optimize performance, but may also save on hardware resources.

PRTG also helps you to properly size your Citrix virtual machines. You may need to assign more CPU and memory to individual VMs to provide for peak performance.


PRTG allows for multi-level Citrix monitoring

 i How PRTG defines sensors

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

The first step in Citrix performance monitoring is the monitoring of the host. Issues with virtual machines often lie in their underlying hardware. With the PRTG Citrix XenServer Host Sensor you can monitor all the important data of your host. For VMs to run trouble-free, metrics such as CPU load, hard disk usage, and memory/network utilization must be in the right range.

Along with the host, PRTG monitors all the virtual machines running on your Citrix XenServer. With the Citrix XenServer Virtual Machine Sensor you can keep an eye on all the relevant performance data of your VMs, including CPU and memory usage, read and write speed, and network load.

Operating system and applications

Operating system and applications

The next step involves the monitoring of the operating system and applications that are running on your Citrix VM – regardless of whether you are using Citrix XenDesktop, Citrix XenApp, or another product. As an example, WMI is perfectly suited for monitoring your Windows operating system; PRTG even comes with appropriate technologies for other operating systems, such as Linux and macOS.

Hardware and Servers

Hardware and servers

It is absolutely vital that you closely monitor the hardware and servers in your network - even when using virtual environments. Even the very best virtualization software is useless if your network connection is shaky or down because of a faulty router in the network, an unavailable file server, or some other hardware error. For in the event of network failure or bottlenecks in the network connection, your virtual infrastructure also takes a hit.

PRTG comes with several native sensor types which feature a variety of different technologies (such as SNMP or SSH), allowing you to get the very most out of your monitoring by monitoring your entire network infrastructure.


Other custom PRTG sensors

PRTG lets you implement your own sensors so you can personalize your monitoring even more. Check out our Knowledge Base for links to instructions on how to create user-defined sensors with PowerShell to monitor your Citrix environment.

5 good reasons to virtualize with Citrix

Improved use of resources

Improved use of resources

Non-virtualized servers often run at less than 20% capacity. As a result, precious resources are wasted. With virtualization, you can increase your server capacity to up to 80%. By using these capacities efficiently, you’ll spend a lot less money on new servers.


Greater flexibility

Greater flexibility

Are you in need of increased capacities for the short term? No problem – a few mouse clicks and Citrix XenServer has you covered. You’ll save time and increase your flexibility. Moreover, you can often avoid the cumbersome process of obtaining new physical servers.


Lower energy costs

Lower energy costs

By optimizing server capacity, Citrix virtualization reduces energy costs. Lower energy consumption also translates into a decreased need for server room cooling and a longer-lasting data center.


Less money spent on maintenance

Less money spent on maintenance

Virtualization with Citrix XenServer also lowers maintenance costs. Its easy-to-use software and straightforward maintenance are two of the things administrators love most. You can even use the virtualization to reduce the size of your data center, and thereby lower ongoing expenses such as rent.


Become an indispensable part of your company

Become an indispensable part of your company

A good virtualization strategy with Citrix XenServer shows that as an admin, you work efficiently and with an eye on costs. As a result, you’ll be seen as an innovator and as an indispensable part of the team by upper management. With PRTG monitoring, you’ll achieve total control of your Citrix environment and can prevent downtime completely.
