How NetOcean Works

  • Service endpoint is a back-end server e.g. shipping service, payment gateway or OTP services.
  • NetOcean works as a replacement of service endpoint server.
  • First we capture the actual request and response flows between system under test and service end point and store them in NO.
  • Now, when service end point is not there then NO serves the response of a particular request coming from system under test.

Quick Start Guide for Using NetOcean

User needs to perform the following steps to deploy a virtual service using NetOcean:

  1. Record request and responses or Add Service manually
    • Automatic or Manual mode
  2. Parameterization
    • Identify content in requests which affect response
    • For example – account number in Account Summary request
  3. Define response customization
    • Response Templates
  4. Activate service
    • The Service is ready for use!! Point the application to the controller IP and port and user is ready to go.
  5. Use additional features:
  • Parameters
    • Hold values needed for response generation
    • Assigned from Requests, HTTP headers, URL Query parameters
    • Generated by NetOcean (e.g. system date, random number, counters)
    • Loaded from indexed datasets (e.g. account details based on account id)
  • Defines how response is generated
    • Based on data (parameters) in specific request
    • Custom logic, if needed

Service Virtualization

  • Service Creation: Record request and responses or Add Service manually
  • Service Correlation: Capture dynamic values passed from the client to the server and send the response based on these dynamic values.
  • Parameterization: Identify content in requests which affect response and add them to response
  • Response Templates: Predefine response file that serves as a starting point for a new response.

Structure of NetOcean


Service is a collection of request and response. Each service has a unique name and is associated with a key like URL of the web service. Service comprises of Templates, Parameters, and Service Settings Services are added either by recording existing services or manually using Add Service feature.

Sample Request

Sample Response

A Service has following components:

  • Templates
  • Data Source
  • Parameters
  • Service Settings

Services are added either by recording existing services or manually using Add Service feature.


User can use templates to define the response of a service. Templates use various parameters to send the appropriate response based on the request data. One service can have one or more templates. In case of multiple templates, conditions are used to select the template for the matching response.

Data Source

Data Sources are global data source which can be used by one or more services. Data from data source are used for parameterization of the response templates, selection of the template and index for index data set.


Parameterization is a technique to change the recorded value in the script to some other value during the run-time. Parameterization is needed to generate real-life load, while optimizing the size of the script and avoiding cache effect. For example, to perform the script’s actions (query or submit) using different values from those recorded, we replace the recorded values with parameters. It is mandatory in situations where different user-ids are needed to login in form of a real-life load scenario.

Following types of parameters are supported by NetOcean:

  • Search Parameter
  • Request parameters
  • URL query parameters
  • Scratch parameters
  • Scratch Array parameter
  • Dataset
  • Indexed dataset
  • Data/time parameters
  • Random number
  • Random string
  • Unique number
  • Cookie parameter
  • XML Parameter
  • Conditional Logic based parameter values
  • Select Data Source
  • Indexed Data Source

Service Settings

Service settings are used to configure the following settings:

  • HTTP settings
  • Additional HTTP Headers
  • Trace level
  • Service Time Delay
  • Comments
  • Callback Methods

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. At the top-right corner, the count of active sessions and active users is displayed.

Upon expanding the record, detailed activities of the user along with the various details, such as activity time, IP address, session ID, user name, module name, activity name, description, and response time (ms) is displayed.

Columns Selection: The user can select columns to be displayed from the drop-down list.

‘Group by’ Columns: 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.

Download Report: You can download Audit logs (the logs of user activity performed in dashboard) in three formats – PDF/Word/Excel.

Other Actions

SR No. Action/Icon Description
1 Include Inactive Session Select the check box to include inactive sessions in the Audit log report
2 To generate user session report
3 To filter / search a record
4 To refresh the Audit log list

User Sessions Report: This report displays number of users and sessions per day, number of sessions per user and activities count of each activity and its module, done by user in between a specified period in three different tables as follows:

  1. Summary: Displays date wise number of active users and its session count. The details include Date, LOB, Environment, Application, Application URL, number of Unique Users, and number of Sessions along with Session Duration (Avg duration, Min duration, and Max duration).
  2. Top N Users: Displays number of sessions count per user (unique) between the specified period. The details include LOB, Environment, Application, Application URL, Users, and number of Sessions along with Session Duration (Avg duration, Min duration, and Max duration).
  3. Top N Activities: Displays the count of per activity performed by user in the specified period. The details include LOB, Environment, Application, Application URL, Module, Activity, and Activity Count along with Response duration (Avg, Min, and Max).

Key Pointers

  • In case of multi-dc, the tables displayed are – Summary, Top-N Users from each application, and Top-N Activities from each application.
  • For summarized table, two chart are displayed, which shows the relation between date and number of users, date and number of sessions. The first chart displays dates on X-axis and number of user count on Y-axis. The second chart displays dates on X-axis and number of session count on Y-axis.
  • Activities, such as Login attempt failed, Login attempt failed due to maximum session limit reached and its session are not counted as active user, active session for summary table, and Top-N user table. This data only come in Top-N Activities table.
  • An HTML link is provided on the number of unique users in the summary table of User session report. To see date wise user list, click or CTRL+Click the user count in summary table. A click opens an HTML in the same tab and ctrl-click opens an HTML in a new tab. This html contains the date wise user list.
  • The current date and time is displayed at the end of report URL to get the actual data when the report is generated.

Generate a User Session Report

  1. Click the icon, specify the time period for the report generation, and click the Apply button.

  1. To generate the user session report, click the icon. The report gets generated and displayed in PDF format. Few are some sample sections of the generated report.

Generate Token

This feature allows only an authorized user to access external REST API URLs. To access URLs, you need to generate a security token, and use it in REST calls for authentication and authorization purpose. Server validates 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, you cannot access the URL with this token. You need 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 This displays the Generate Authentication Token window.

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

This generates a token, which is valid for the specified duration. You can generate multiple tokens. To copy the generated token, click the Copy button.
