Getting Started with NDE

Once the NDE machine is installed, user can login to the system and access various features of NetDiagnostics Enterprise.

Login to NetDiagnostics

User needs to follow the below mentioned steps to login to NetDiagnostics:

  1. Open web browser and type the following address in the address bar and press ENTER. http://<hostname>/NetDiagnostics.
 note <hostname> in the address bar is the name of the Server on which NetDiagnostics is running.  For example, if the NetDiagnostics is running on a Server named Hostname Server, the URL is http://HostnameServer/NetDiagnostics/.
  1. The NetDiagnostics login window is displayed as illustrated in the image.


  1. Enter the Username and Password and click Login. User logged-in into the NetDiagnostics system and NetDiagnostics – Home page is displayed.

Product Home Page Description

ND Home page consists of a left pane and a right pane. Left pane contains a menu, which enables a user to view details on sessions, scenarios, monitors, and various other sections. Using these menus, user can access further sections and can perform various operations, such as compare sessions, generate reports, access various features of web dashboard and application end-to-end view, and so on. On the right pane, summary of all-important aspects is displayed, be it a release version, CPU usage, memory utilization, or alerts generated in the system.

Left Pane

It contains following menus / sub-menus, and menu items:


  • Dashboard: This displays the current Dashboard.
  • Application End to End View: To view end to end monitoring approach.
  • Geo Map: To view Geo map.
  • DB Monitoring: This is a powerful feature to measure the performance of each query contributing in a session execution. It provides complete monitoring of MSSQL queries with insights into SQL activity, wait statistics, databases, support services, Temp DB, and high availability. It enables a user to detect such queries, which are consuming more resources as compare to normal ones. Once identified, user can diagnose the issue and perform corrective measures.


  • Compare: This feature is used to compare two test runs. User can perform further actions for post compare operation:
    • Enable Compare: To apply the comparison.

Favorites: Favorite allows a user to save current view of Real Time Graphs (RTG). User can create a new profile by saving current view of RTG UI as a profile. If user wants to see current view of graphs next time in Web Dashboard, then user needs to add graphs in favorite. When user loads saved favorite, then all graphs of favorite are displayed in Web dashboard’s graph panel.
