This article applies to PRTG Network Monitor 12 or later, as well as to previous (deprecated) versions

Add Custom Device Icons

In order to extend the icons available in a device's settings, please copy any 14x14 pixels PNG image you would like to add into a sub directory of your PRTG program directory. The correct sub folder differs, depending on the PRTG version:

For PRTG version 13.2 or later, please use: \webroot\icons\devices\

For PRTG version 12 through 13.1 (as well as in previous deprecated versions), please use: \website\icons\devices\

After adding it, the icon will show up immediately the next time you enter a device's settings page.


  • The image must have exactly a size of 14x14 pixels. If it does not match this size, it will not be clinched/stretched automatically on all pages of the web interface!
  • The image must be saved in PNG format. If it does not match the PNG extension, it will not show up in the icon list.
  • Avoid blank characters in the filename (e.g. instead of web server.png use webserver.png or web_server.png)

Using More Than One Web Interface

When using several web interfaces in a cluster, please make sure you add the additional icons on every cluster node, so they show up in whatever node's web interface you log in.

If a custom icon is set for a device, but it does not exist in the respective sub-directory of a node's installation, the web interface of this node will show a standard device icon instead.
