SO Monitoring app creates a blank tab
If when selecting SO Monitoring from the portal a blank tab labeled “SO Monitoring” is returned, then the issue may relate the URL you are using in portal by default.
A fix for this issue is to change “https” to “http” and change the port from “30225” to “30215”, within the browser url.
IE using this url “http://portal.api.simpledemo.onap.org:30215/ONAPPORTAL/applicationsHome” instead of the default “https://portal.api.simpledemo.onap.org:30225/ONAPPORTAL/applicationsHome”.
