Install OneAgent on Windows

This page describes how to download and install Dynatrace OneAgent on Windows.

Then continue with the installation steps provided below.


  • You need administrator rights for the servers where OneAgent will be installed as well as for changing firewall settings (necessary only if your internal routing policy may prevent Dynatrace software from reaching the Internet).
  • You need permissions and credentials for restarting all your application services.
  • You need to check also the disk space requirements.
  • The host on which you install OneAgent needs at least 200 MB RAM.
  • OneAgent installation isn't supported on networked storage mount points that are managed by standards such as NFS or iSCSI.
  • All hosts that are to be monitored need to be able to send data to the Dynatrace cluster. Depending on whether your Dynatrace deployment is on SaaS, or on Managed environment, and on your network layout and security settings, you may choose to either provide a direct access to Dynatrace cluster, or to set up an ActiveGate.

OneAgent Windows installer doesn't support the modify and repair operations. You can't reinstall OneAgent using the same installer version as the installed OneAgent. To reinstall OneAgent, uninstall it first or simply install a newer version.


In the Dynatrace menu, select Deploy Dynatrace.

Click the Start installation button and select Windows.

Provide a PaaS token. The token is required to download OneAgent installer from your environment. If you don't have a PaaS token, you can generate one right in the UI. The token is automatically appended to the download command you'll use later.

Download the installer. There are two options:

  • Select Download OneAgent installer to download the Windows installer (EXE file) for single-server installation.
  • Download via Windows Command Prompt. Copy and run the command. Note: this command will only work with PowerShell 3.0 and TLS 1.2 (or .later)

optional Customize your installation

  • Set a network zone for this host.
  • If your environment is segmented (for example, into development and production), consider organizing your hosts into host groups.
  • You can override automatically detected host name. This is useful in large and dynamic environments, where defined host names can be unintuitive or can change frequently.
  • You can also apply tags to the host to organize your monitored environments in a meaningful way.
  • Enable Infrastructure Monitoring in place of Full-Stack Monitoring.
  • Disable Log Monitoring.

Note: OneAgent command-line installer provides more options to customize your installation.

Run the executable file and follow the displayed instructions. If you set customized options, use the provided command and run it from your download folder. It contains all the installation parameters reflecting your custom settings.

Restart all processes that you want to monitor. You’ll be prompted with a list of the processes that need to be restarted. Note that you can restart your processes at any time, even during your organization’s next planned maintenance period. Though until all processes have been restarted, you’ll only see a limited set of metrics, for example CPU or memory consumption.

It’s recommended that you install the version of WinPcap that is packaged with the OneAgent installer. Its library is the cornerstone of Dynatrace network analysis. We’ve packaged the library in such a way that its DLLs are seamlessly integrated with Dynatrace software, thereby enabling unattended updates and other advantages. If you already have WinPcap installed, please remove it before OneAgent installation. The installer includes the latest, unmodified version of the library—so any other software you have that relies on WinPcap won’t suffer from library loss.

You've arrived!

Great, setup is complete! You can now take a look around your new monitoring environment. If you are a SaaS customer, you can access your monitoring environment anytime by going to Dynatrace website and clicking the Login button in the upper-right corner. If you are a Dynatrace Managed customer, you can access your monitoring environment through the Cluster Management Console.


One last thing: to monitor your processes, you need to restart them. At any time, you can check which processes aren't monitored and need to be restarted. Just select Deployment status from the navigation menu, click the All hosts or Recently connected hosts tab, and expand the host you are interested in.
