PRTG Manual: PRTG Status—Auto-Update

Whenever a new version of the software is available from the Paessler website PRTG will download the setup file automatically if a direct internet connection is available. The administrator will then receive a ToDo ticket with instructions to initiate the update installation.

For customers using a Freeware or Trial Edition, automatic software updates are available at any time. Customers using a Commercial Edition need to have an active maintenance contract so updates are available.

Using Auto-Update

Note: This documentation refers to the PRTG System Administrator user accessing the Ajax interface on a master node. For other user accounts, interfaces, or nodes, not all of the options might be available as described. When using a cluster installation, failover nodes are read-only by default.

To view the auto-update page of your PRTG installation, select Setup | Software Auto-Update from main menu.

If there is a new version available, you will see detailed information about the available version. Please read these notes carefully!

In order to install an available version, click the Install Update [version number] button. You will be asked to confirm installation and license—and that's it!

Click on the button Show Auto-Update Log to show corresponding log entries.

Manually Install an Interim Update

Not all available updates from Paessler will be pushed to all customers, but they are still available from the website. Sometimes Paessler support may ask you to update to the latest version.

In this case please click the Check For Latest Update and Download button. PRTG will then connect to the Paessler servers and download the setup file, regardless of the status of the update-check. Then Install Update [version number]. Note: In order to use this function, a direct internet connection is necessary on the computer running the PRTG core server.

Select Other Release Channel

PRTG is available in three different release channels. For details about continuous rollout and release channels, please see the blog article in the More section below.

  • Stable: Updated about once a month. Best tested versions. We recommended this channel for live environments you have to depend on!
  • Preview: Updated about once a week. Thoroughly tested in our labs, but may still contain limitations in certain monitoring configurations
  • Canary: Updated every night. Use with caution! Software versions in this channel are not tested yet, might contain severe bugs, and are provided for testing purposes only. We strongly recommend to not use those versions in live environments you have to depend on!

In order to change the release channel you receive updates from, please open the System Administration—Core & Probes page by clicking on the Select Other Release Channel button and change settings in the PRTG Software Auto-Update section.


There are a few things we ask you to consider regarding automatic software updates:

  • In order for auto-update to work the machine running the PRTG core server needs direct internet access. If a proxy connection is needed, please configure it in the System Administration—Core & Probes settings. For details about the update servers, see More section below.
  • During installation the core server may be restarted without notice.
  • Existing remote probes will be updated automatically, causing short downtimes in monitoring of remote locations. In rare cases a manual update of remote probes is required after you update the core server. In these cases you will be notified in the device tree, and monitoring of remote locations will be interrupted until you perform the manual update on the system(s) running the remote probe(s).
  • In a cluster installation the update needs to be installed on one node only. The new version will then be deployed to all other cluster nodes automatically (causing a short downtime for the monitoring on the cluster nodes, one after another).
  • If you run several individual PRTG core servers that are not in a cluster, for example, in combination with the Enterprise Console, an update has to be initiated and confirmed for each single core server.
  • You can disable automatic downloading in the System Administration—Core & Probes settings. Updates will then only be downloaded on request, when you click on the Check For Latest Update and Download button.
