Dear Dimak

The sunburst font size is automatically chosen by PRTG and cannot be changed. PRTG tries to find the optimal font size to usefully label as many object as possible while avoiding too many abridged labels.

But if it is not well enough for our needs, Can't we change it with CSS or anything?

Changing the font size in sunburst would help the reading image in large screen in monitoring room. Even changing the percentage on fill would be good.

Dear tzihad

The font size is mostly limited by its height when the outer rays are rendered. I am sorry, but we have currently no plans to make the sunburst configurable through the user interface. A javascript can be found at C:\Program Files (x86)\PRTG Network Monitor\webroot\javascript\, called _Prtg.ObjectTree.Sunburst.Plugin.js. This file includes the font size computation.

Please note that changes to that file are not covered by technical support.

Perfect! changed the font size to bigger, it cuts a little bit the long text but at least now we can see well everything on our monitor :) Thanks!

Can we please at least have a decent font for the sunburst? Like a Sans Serif of any kind?

Dear comma

The sunburst already uses a sans-serif typeface.

Dear Arne, With my installation it does now, with the last update.

Dimak , what did you change to get a bigger fontsize ? i looked into the java file but i have no clue where the font calculation takes place.

I changed the /1.8 to different values , so as *1.5 , buth both to no success

the fontsize is so small i cant even read it on 2 stacked 17"monitors each showing half the sunburst map.
