Update Dynatrace Managed

To run a successful update, you need at least 3 GB of available space on the partition where Dynatrace Managed is installed.

Update of Dynatrace Managed consists of two steps:

  1. Downloading the update package.
  2. Performing the actual update.
Sequential updates

Updates of Dynatrace Managed can only be done sequentially with regard to versions. If your Managed cluster currently runs for example, version 1.146 and you want to upgrade it to version 1.150, you'll have to upgrade first to version 1.148 and then to version 1.150.

Package download

Typically, the update package download occurs automatically. If you wish to download the update packaged manually, the automatic download can be disabled on demand only via the Mission Control.

For servers not connected to Mission Control (offline servers), upon update release, you will receive an official email with a link to download the update package.

For automatic updates, all you need to do is specify a convenient time when your users won't be using Dynatrace Managed and the system can upgrade itself (for example, during a previously scheduled maintenance window).

Update in progress

Your monitoring and cluster management pages won't be accessible during the upgrade process if your cluster consists of only two nodes or the upgrade requires a restart of all nodes simultaneously (rare occurrence).

To define a start time for automatic updates:

From the navigation menu, select Settings > Automatic update.

Set the Install Dynatrace cluster updates automatically switch to the On position.

Cluster license

This switch is disabled if the license for the cluster has the Enforce automatic cluster updates feature enabled. In such cases, even the cluster administrator can't change this setting.

Specify a weekly maintenance window start time. Dynatrace Managed updates will start at the time you specify.
This setting doesn't affect the download of updates.

Manually triggered update

For manually triggered updates, you have to trigger the actual update with the user interface or via the REST API. Once triggered, the update process is performed in the same way as in the automatic updates. Typically, you would use the manually triggered update if you wish to initiate the update outside scheduled maintenance window.

Offline cluster update

Offline cluster is a cluster with a specific license that permits this cluster to operate in closed environments. These clusters are administered by Cluster Management Console (CMC). Once the update is announced, you will receive an email with a link to download the update package.

To update an offline cluster:

Download the update package from the official source to the node.

Use the Cluster Management Console (CMC) to upload the patch to the cluster.
The Cluster Management Console will propagate the update package to all the nodes and execute the update in the same way as in the automatic updates.

Manual update

For manual update, you must manually download the update package, manually propagate the update package to all your cluster nodes and manually initiate the update script.

Update nodes in sequence

Since the node that is being updated is not operating, it is crucial that you manually update in sequence.
Wait until the node update completes before starting an update on the next node.

To manually update the cluster, perform this procedure for each node perform in sequence:

Download the update package from the official source to the node.
You can copy the update package into any convenient path on the node system.

Give update package executable permissions. Use Linux chmod command.

[root@localhost]# chmod +x update_package.sh

As a root user, execute the update script with the --upgrade-nodekeeper parameter.
Wait until the node-keeper update is complete.

[root@localhost]# ./update_package.sh --upgrade-nodekeeper

As a root user, execute the update script with the --upgrade parameter.
Once the update completes successfully, move to the next node and repeat the procedure.

[root@localhost]# ./update_package.sh --upgrade

Dynatrace Managed version check

To check which Dynatrace Managed version you currently use:

Log into the Cluster Management Console or one of your monitoring environments.

Open the User menu in the top right corner. The version number appears at the bottom right corner of the User menu.


Navigate to the home page of your Cluster Management Console, where you can view your Dynatrace Managed deployment status.

Click a Dynatrace Managed node to open the overview page of this node. The installed version appears right under the title of the page.
