Install Dynatrace Managed in offline mode

How-to guide
8-min read

Dynatrace Managed is available in an offline version. In offline mode, Dynatrace Managed uses an offline license that disables all features requiring an internet connection — such as connecting to Mission Control for license reporting and health checks, or receiving automatic cluster updates.

In offline mode, you are responsible for keeping Dynatrace Managed up to date and reporting license usage to Dynatrace.

To install in offline mode, pass the license file using the --license-file <license-filename> parameter. The activation email includes the full installation command with this parameter and the offline license file attached. The installation log confirms offline mode with offline mode is active entries.

The server verifies the license after startup (not during installation) through a signature (hash) included in the license file. The installer copies the license file to the server's config directory. The license.file entry in the server's config.properties file contains the path to this file.

The Dynatrace Server does not include installation packages for OneAgent or ActiveGate — in online mode these are downloaded automatically from Mission Control. In offline mode, they must be added manually. Download links are provided in the activation email.

Review requirements

Ensure that your system meets the hardware requirements and system requirements.

Avoid installing the data stores for Dynatrace Managed components on network or remote disks — this can cause performance and stability issues.

Download files

Download the following files from the activation email and copy them to the directory on your Linux host where you want to install Dynatrace Managed:

License file (license.lic).
Dynatrace Managed installer (cluster installer).
OneAgent, RUM JavaScript, ActiveGate, and Synthetic installation packages (agents bundle).

Activation email example

managed-activation-email

Verify installer

The Dynatrace Managed installer is digitally signed. Use OpenSSL and the Dynatrace root certificate to verify the installer's authenticity. The signature file has the same name as the installer with a .sig extension.

Download the Dynatrace root certificate and the installer signature file using the links provided in the activation email.

Verify the installer file signature using this command:

openssl cms -inform PEM -binary -verify -CAfile dt-root.cert.pem -in dynatrace-managed-<version>.sh.sig -content dynatrace-managed-<version>.sh > /dev/null

Replace <version> with your Dynatrace Managed version.

A successful verification returns Verification successful. On failure, you see Verification failure followed by details.

Retrieve SBOM file

Follow the instructions in step 3 of the cluster installation guide to retrieve an SBOM file.

Run installer

Follow the instructions in Run installer (step 4) and Finalize setup (step 5) of the cluster installation guide. Use the --license-file parameter instead of a license key:

sudo /bin/sh dynatrace-managed-<version>.sh --license-file license.lic

Replace <version> with your Dynatrace Managed version.

Activate license

After the installation, activate your license.

Log in to Cluster Management Console.
Go to Licensing and select Activate license.
- If you have internet access, you are redirected to an external registration form (https://mcsvc.dynatrace.com/register.html) with all fields pre-filled. Verify the details and submit.
  - If you don't have internet access, open https://mcsvc.dynatrace.com/register.html in a browser with internet access and complete the form manually.
  - Required: License key and Cluster identifier
  - Optional: Installed version (the current cluster version) and Cluster admin email address (an email address through which Dynatrace product experts can contact cluster administrators in case of an emergency)
Select Activate license. The next page confirms that the license has been activated.
On the confirmation page, select Download license file to download the license-activated.lic file.
Select Go to Licensing page.
On the Licensing page, select More (…) > Apply license in the upper-right corner.
Select the license-activated.lic file you downloaded earlier.
- After applying the license, the license status changes to Active.

Upload agents bundle

To upload the agents bundle to the cluster:

Log in to Cluster Management Console.
Go to Settings > Automatic update.
Select Upload installation package to upload it to the cluster.

Alternatively, you can manually copy the agents bundle to the following directory on your Linux machine:

/var/opt/dynatrace-managed/agents

Update Managed Cluster in offline mode

Follow the semi-automatic Managed Cluster update instructions in the update guide.

FAQ

What can I do if an error occurred while uploading the installation package?

An installation package upload error typically occurs when attempting to upload a full package containing a Managed installer, OneAgent, RUM JavaScript, ActiveGate, and Synthetic. In this case, the package size exceeds the 2 GB upload limit.

Log in to Cluster Management Console.
Go to Settings > Automatic update.
Select Upload installation package to upload only selected installation packages to the cluster.

Alternatively, you can manually copy installation packages to the following directories on each cluster node.

For the cluster to:

/opt/dynatrace-managed/installer/upgrade

For OneAgent, RUM JavaScript, ActiveGate, and Synthetic to:
```
/var/opt/dynatrace-managed/agents
```

What can I do if there is a problem with the license?

If the license file is corrupted, the installation completes and the server starts, but it indicates a problem with the license. In this case, upload a new license in Cluster Management Console. For details, see Update offline license.

How can I update the license?

To update your license:

Download the license.lic file from the activation email.
Log in to Cluster Management Console.
Go to Licensing and apply the new license.

How can I obtain diagnostic data for further analysis?

In Cluster Management Console, you can download diagnostic data. For details, see Diagnostic archives.
