While I am able to get to the config.php page, whenever I select an option such Overview, Open in NagVis, or the demo-server and demo2 maps, I get the following error message: The given instance name "default" in backend "ndomy_1" is not valid. This error occurs if I am at the server console, or if I am viewing it from a remote host. I made several changes to the nagvis.ini.php file, and I have enclosed a copy of the with this e-mail. Can someone tell me what I need to change in order to get NagVis to work properly? Thanks. <<nagvis.ini.php>> <pre> The information in this e-mail is intended only for the person to whom it is addressed.
