Monitor health and performance of the Hyper-V clusters, hosts and VMs.
Extension- Product information
- Release notes
Overview
Get insights into performance of the Hyper-V fabric, tracking health, performance and resource utilization of the Hyper-V VMs, together with the context of their host and cluster resources. Monitor Hyper-V clusters, detect problems ahead of serious impact, and pinpoint the bottlenecks in the virtualization and application layer, including:
- Processor bottlenecks
- Memory shortages
- Network overload
- Storage shortages
- Slowness in the dependent applications hosted on the Hyper-V cluster
Hyper-V extension leverages PowerShell cmdlets and WMI queries to collect data from the Windows hypervisor, following best practices employed by Microsoft, as well as Dynatrace customers who contributed to validation of this extension in real-life situations.
Use cases
- Monitor health and performance of your Hyper-V cluster, using built-in analysis screens and easy-to-navigate dashboards
- Make sure resources are split optimally between the virtual machines
- Relate performance of the applications and VMs monitored with OneAgent to the underlying Hyper-V resources allotted to the VMs
Compatibility information
This extension requires:
- x64 OS with BIOS-activated virtualization:
- Windows 10 Enterprise/Pro/Education
- Windows Server 2016 or newer
- Hyper-V VM Configuration Version 9.0 or higher
Note on topological relationships between discovered Hyper-V VMs and OneAgent-monitored VM instances:
- This extension maintains SAME_AS relationship between discovered VMs and OneAgent-monitored instances of the guest OS, using IP address as the join property.
- This relationship enables:
- Davis AI analytics to look together at metrics obtained by this extension and from OneAgent, to completely characterize monitored guest OS instances performance
- Discovery and Coverage app to suggest which discovered VMs should be instrumented with OneAgent for full visibility into performance
- This relationship works for known Windows guest OSes, but has limitations when guest OS is Linux. This limitation stems from the fact that on Hyper-V, Linux guest OS should be instrumented with the Microsoft's Linux Integration Service, while this service supports limited spectrum of the Linux distributions. See the link for details.

⚠️IMPORTANT CHANGES
- This extension release requires Dynatrace cluster version 1.313 or later.
- The extension now runs with elevated privileges, which requires editing the extensionsuser.conf to allow the extension to run with such privileges. In return, you get much improved scalability and stability of the monitoring. See the tile text for more details.
- Breaking change this upgrade will require recreation of the monitoring configurations.
New features
- Added the ability to interpret entity filters as an allow or deny rule, which simplifies filtering configuration and makes it more flexible.
- The dt.security_context attribute is now propagated to all entities created by the extension. When enabling entity access control based on dt.security_context ensure you set the Grail security context destination property to dt.security_context.
- Enabled the extension to present the Dynatrace Platform (a.k.a. Gen3) entity details screens in the future platform apps that will expect these screens.

Published Thu Apr 04 2024
New features

2.0.12
Published Mon Feb 26 2024
New features
- This release introduces an important change Hyper-V extension requires local activation now (i..e. activation on an OneAgent-instrumented host).
- Previous releases allowed remote installation (i.e. activation on an ActiveGate), but because of Hyper-V specifics, this very often caused permission issues that severely limited extension functionality and weren't solvable. So anyway - we have been advising you to move to local activation. Now it's the only way to activate this extension.
Patch level changes
- Additionally, this release fixes some issues with filtering monitored entities.
2.0.10
Published Fri Feb 09 2024

2.0.3
Published Wed Nov 29 2023
Patch level changes
- Fixed a bug affecting extension activation under certain conditions. Extension logs on affected systems reported "AttributeError 'dict' object has no attribute 'feature_sets' "
