This happens because of the plugins not being installed correctly. Because of it Horizontal Discovery Sensor doesn't get installed in the system. You can follow the below mentioned resolutions.

Resolution1:

Login to your instance the go to "discovery_sensor" table and upload the attached xml.

Resolution2:

Uninstall all the plugins that you have installed for Discovery.

Then go https://developer.servicenow.com/dev.do#!/home site and go to the profile section you can see "Instance Action" under it you can see Activate Plugin option click on it then look for discovery in the list and then click on Activate option and wait for it to get installed once it is installed you will get an email informing the successful installation. After this the issue will be resolved
