Remote Windows Host Monitoring extension
- Latest Dynatrace
- Extension
- Published Oct 27, 2025
Monitor health and performance of Windows Hosts without installing an agent.
Get started
Overview
This extension leverages the WMI protocol to collect data from Windows hosts, without the need for OneAgent. This enables agent-less, remote monitoring while providing the same transparency and visibility of Windows hosts as otherwise only offered with a OneAgent installation.
This is intended for users, who
- Want to monitor Microsoft Windows hosts
- Can’t install OneAgent on the host
This enables you to
- Remotely monitor windows host
- Collect all relevant data like:
- CPU and memory utilization
- I/O operations and disk usage
- Network interface and traffic statistics
- Details of processes and network services running
Compatibility information
- All versions of Windows supported by Microsoft
- Successfully tested on older version of Windows and will provide best effort support for older OS's
Details
The Remote Windows Host Extension is built on top of the new Extension Framework.
The Extension package contains
- WMI DataSource configuration
- Dashboard template
- Unified Analysis screen template
- Topology definition and entity extraction rules
Further information about the extension can be found in the Dynatrace Product News Blog

Feature sets
When activating your extension using monitoring configuration, you can limit monitoring to one of the feature sets. To work properly the extension has to collect at least one metric after the activation.
In highly segmented networks, feature sets can reflect the segments of your environment. Then, when you create a monitoring configuration, you can select a feature set and a corresponding ActiveGate group that can connect to this particular segment.
All metrics that aren't categorized into any feature set are considered to be the default and are always reported.
A metric inherits the feature set of a subgroup, which in turn inherits the feature set of a group. Also, the feature set defined on the metric level overrides the feature set defined on the subgroup level, which in turn overrides the feature set defined on the group level.
