It's a bit of a hack, but it's possible:
Edit the file “C:\Inetpub\SolarWinds\Orion\js\NetObjectTips.js” and remove the following lines:
this.tooltip = 'processed';
BTW, be very careful. If you edit this incorrectly, there is a good chance that it won't work at all.
Thanks, it works.
To bad to lose the function but it's better anyway.
