<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> 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 PRTG System Administrator user 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 to receive updates.



icon-i-round This documentation refers to the PRTG System Administrator user accessing the Ajax interface on a master node. If you use other user accounts, interfaces, or nodes, you might not see all of the options in the way described here. If you use a cluster installation, note that failover nodes are read-only by default.

To view the auto-update page of your PRTG installation, select Setup | Auto-Update from main menu. On the Status tab you can download and perform updates.

Using Auto-Update

If there is a new version available, you will see detailed information about the available version. Please read these notes carefully! You find a summary of current and past release notes below the update section. For detailed release notes, click PRTG Release Notes and Version History which will redirect you to the version history page on paessler.com.

To install the latest available version, click Install Update [version number]. PRTG will ask you to confirm installation and license—and that's it!

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: To use this function, a direct internet connection is necessary on the computer running the PRTG core server.

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.

Software Auto-Update

When a New Version is Available

Define what to do when there are software updates available. Choose between:

  • Automatically download and install the latest version: PRTG automatically downloads and installs any new version as soon as PRTG detects that there is a newer version available (PRTG checks this once per day).
    Note: Without prior notice, the installation of a new version will restart the PRTG Windows services and may also include a server restart.
  • Automatically download the latest version and alert the admin: PRTG automatically downloads any new version as soon as PRTG detects that there is a newer version available (PRTG checks this once per day). After successful download, PRTG will create a ToDo ticket for the PRTG System Administrator user.
  • Alert the admin only: When PRTG detects that there is a newer version available, it will not download updates automatically, but create a ToDo ticket only. You can still download updates manually on the Auto-Update page.

Installation Time

If you select the automatic installation option above, choose the desired time for installation of updates from the drop-down menu.

Release Channel

PRTG updates are delivered in different release channels. You can choose between maximum stability, or most early access to new features. Please choose between:

  • Stable: Updated about once per month (most conservative option, recommended): These are our best tested versions. Choose this channel for live environments you have to depend on!
  • Preview: Updated about once per week: Versions in this channel are already thoroughly tested in our labs, but may still contain limitations in certain monitoring configurations. Choose this channel if you are willing to take a little risk for the benefit of getting new features and bug fixes a little earlier. We strongly recommend to not use those versions in live environments you have to depend on!
  • Canary: Updated daily (testing only, should not be used on live systems): 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!

For more information about the different release channels, please see the blog article linked in the More section below.

Click Save to save your settings. If you change tabs or use the main menu, all changes to the settings will be lost!


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 the More section below.
  • During installation the core server may be restarted without notice.
  • PRTG updates existing remote probes 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). If a server with a probe uses several network connections with different IP addresses, ensure these addresses are included in the list of allowed IPs. Otherwise the remote probe on this machine might be disconnected after an update.
  • 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 on the Auto-Update Settings tab. Updates will then only be downloaded on request, when you click on the Check For Latest Update and Download button.
  • PRTG does not start auto-update downloads if there is less than 500 MB disk space available on the core server system. If this is the case, you can check this on the Log tab.
