Accessing Web Dashboard

User needs to follow the below mentioned steps to access the Web Dashboard.

1. Open the product login window.

2. Enter the Username and Password and click Login. The user logs-in into the system and Product UI window is displayed.

User Permission (Capabilities) Indication

This enhancement indicates the capabilities, which is assigned to a user so that user can have access to this information from all screens. For example, one of the capabilities in which guest user falls in is “ReadOnly”.

If that user has multiple capabilities, it is displayed in a comma separated format.  The list of capabilities is also displayed for Multi DC environment as well.

Product Home Page Description

Product home page consists of a left pane and a right pane. Left pane contains a menu from where a user can view details on test runs, scenarios, monitors, and various other sections. Using this menu, user can access further sections of the web dashboard and can perform various operations, such as compare test runs, generate reports, access various features of web dashboard, and so on. In the right pane, summary of the important aspects is displayed, be it a release version, CPU usage, memory utilization, or alerts generated in the system.

Multi-Data Center Monitoring

This feature provides users the capability to monitor multiple data centers within a single dashboard. In current days, all the e-commerce applications are moving into multiple data centers to accommodate the application complexity. Now, we have enhanced monitoring capability with the evolution of multi DC in a single dashboard. This advanced technology enables a user to use a single dashboard to monitor multiple data centers. There is a master data center among all the data centers, which allows a user to view the Dashboard of all the data centers.

In the below screen, the metrics are displayed for all data centers:

To view metrics of a particular data center, go to the Data Center drop down list (at the top) and select the required data center from there.

Then, only the metrics of that particular data center is displayed.

Topology is also defined for Multi-DC environment. To view this, go to the graph tree and navigate to the data centers:

In multi-DC environment, there is a group for data centers. Within the data center, there are tiers, servers and instances.

Multi-DC environment support can also be seen in the session window as follows:

In the above image, it can be seen that same session is running at different data centers.

Other features supported in Multi DC:

• Parametrization and Filters on Favorite.
• Lower Panel operations, such as show/hide metrics.
• Zoom Operation for derived Graph.
• Open Merge with Pattern.
• Capability name assigned to logged-in user is displayed in dashboard of Multi-DC in the Logged-in user’s button tooltip. If logged-in user is having multiple capabilities, it is displayed in comma-separated format.

Audit Log

Audit log displays the activity log details of all users. Initially, it displays number of users currently logged in.

In Audit log, entries are populated in audit log files for only those actions of users, which affects user’s object, such as add, edit, update, delete.

Audit log is a separate feature whose permission can be provided to a user, by default user has the permission to see own audit logs. If we assign audit log feature capability to any user, he/she is able to see all the activities performed by user logged in to that machine.

Audit log window displays User, Session Id, IP Address from where user has accessed, Activity Date Time, and Activity description. Every time when user logged in, then a session id is generated. ‘User’ and ‘session id’ group audit log table. Upon expanding any user, displays its multiple sessions. Upon further expansion of any session, activities for that session is displayed.

• By default, audit log window displays logs for a particular duration (such last n hour). More logs can be filtered by applying filter for specified time.
• Active users (which are currently performing some activities i.e. not idle in last one hour) is displayed in a section of User Management.
• Users with Admin capability can force or log out any other user (Users are forcefully logged out if inactive for ‘n’ duration). If same user is trying to log in from different browser or from different IP (Admin can allow access) then system prompts the user about old active session. After confirmation of user, old session is logged out, this allows user to log in new session.
• Session is not having time restrictions, user can also view Logs for specific period. Full session of user can be displayed if any activity lies between applied period.
• System displays complete log for that session. While finding Historical data, system searches for LoggedIn activity. If not found, then user can configure N hours and search for the same. If LoggedIn activity found, then activity is displayed from there to logged out. During that applied period, if LoggedOut session is not available, then go forward N Hours and search for LoggedOut activity. If found, cover all the activities done till LoggedOut otherwise time bound activities are displayed only.
• By default, logs are displayed for last one hour. User can apply any specified time range and view the logs.
• There is a filter provision on each field. User can filter by user, or session id, activity time, or some text in activity description.

View Audit Log

To view the Audit log, navigate to the logged in user, and click the Audit Log option.

This displays the Audit log window with logged in user details, such as user name, IP, and login time:

Upon expanding the record, it displays multiple activities of the user along with the activity time (as shown in below image):

User can select columns to be displayed from the drop-down list.

In addition, there are various options to select the “Group by” functionality, Such as session Id, activity name, activity time, IP, module name, and user name.

Single Sign On (SSO) support through OKTA

With SSO, a user logs in once and gains access to different applications, without the need to re-enter login credentials at each application. There are set of configurations, which need to be done one time in the OKTA and NDE server and after that user needs to login through OKTA. Upon successful authentication through OKTA, user is not prompted to login again until the user session expires. Both Service Provider Initiated and Identity Provider Initiated modes are supported.

Upon requesting a URL, user is navigated to OKTA login UI. Post successful authentication, user is redirected to product UI home page.

Okta integration is also supported with Multi DC.

When a user, who is not part of any group, tries to login the product into default system view, it is redirected to an error page.

For integration of different applications using OKTA, please contact your Cavisson representative.

Security Token based REST calls

This feature allows only an authorized user to access external REST API URLs. To access URLs, user needs to generate a security token, and use it in REST calls for authentication and authorization purpose. Server will validate the token and allow/discard the request. There is an expiration time associated with every security token, which is taken as input while generation of the token. Once token is expired, user will not be able to access the URL with this token. User needs to get/generate a new token for further use.

1. To access the Generate Authentication Token window, click the  icon beside the logged in user name, and click the Generate Token option.

2. This displays the Generate Authentication Token window.

3. Enter the duration in HH: MM format and click the Generate button.

4. This generates a token, which is valid for the specified duration. User can generate multiple tokens.

5. To copy the generated token, click the Copy button.
