It can be turned off with a workaround
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';
I know it's a bit of a necro, but I just discovered this little hole myself.
Despite the hack, the question remains, is there going to be a way to turn this off on an account by account basis, or maybe only have them for Admin accounts?
