NagVis - can't modify host icon

Hello, i have built a map in nagvis and added some icons (Host Groups) to it. For some reason i cannot right click → Unlock/Modify one of those icons anymore - right clicking only opens the normal web browser right-click menu. Is there another way to edit or remove this icon?

Yes, i am in edit mode. When i mouseover the icon the hover menu shows up as expected, but i cannot select the icon with the right mouse button to modify it.

The NagVis map config files can be found in /omd/sites/[sitename]/etc/nagvis/maps

In https://[servername]/[sitename]/nagvis/docs/en_US/map_config_format_description.html you can find the docs.

Probably you need to find specific hostgroup definition and remove it.

define hostgroup {
 hostgroup_name=servers
 x=100
 y=200
}

I believe I was able to edit the config files without stopping / starting the site in the past. Just don’t try to edit it with both gui as cfg at the same time.
