Transactions

A transaction is an employee action or event in a web application that creates business value for the company. A service manager needs enough granularity to see if employees can efficiently perform specific actions on an application's web page.

The Nexthink web interface defines transactions by specifying start and end events:

Start events are user-defined actions, such as clicking or keypressing on an element to which the action is applied to. For example, clicking on a save button.
End events are page-defined elements that are added or changed. For example, a message or icon appears on the page, or on the contrary, an element disappears from the page.

Nexthink uses CSS selectors to define start and end elements on the application's web page.

Nexthink allows configuring unlimited transactions per application, as long as the total number of transactions across all apps remains under 1000.

Transaction Configuration

Use the configuration form to set up transactions by indicating the start and end of a transaction.

Some applications contain elements that are always a part of the web page. These elements may become visible or invisible with changes to the CSS:

The visible attribute of the element can change.
The class name of the element can change dynamically.
The element might be obscured by another element that includes an attribute or class that can change dynamically.

Adding a new transaction

To add a new transaction:

Select Applications > Manage applications from the main menu.
Click on a chosen application's name to access its configuration.
Click on the Transactions tab from the application's configuration page.
Click on the Add transaction button to open the Add transaction window.

From the Add transaction window, fill in the Transaction start and Transaction end tabs.

Defining the Transaction start

From the Add transaction window, click on the Transaction start tab and fill in the fields.

The following table displays the Transaction start fields and how to define them:

Transaction start field

Description

Transaction name

Enter a meaningful name for the transaction.

Start event type

Pick one of the options depending on how the user triggers the transaction.

A trigger can be clicking, pressing the return key on the keyboard or navigating to the page.

Start event name

Choose a name for the start element that is up to 100 characters long.

When writing the name, use the standard UTF-8 characters set.

Note that copying text from other sources might bring unsupported special characters.

Start element CSS selector

Paste the CSS selector of the page element used to trigger the transaction.

Refer to the CSS selectors section on this page.

Start element text pattern (optional)

In addition to the CSS selector, you can narrow down the start element using a text pattern.

Note that the text might exist in multiple languages for some applications.

Select all matching elements

Tick this box to select all elements matching the element id.

This can be useful, for instance, to trigger a transaction when a user clicks on any table row.

Defining the Transaction end

From the Add transaction window, click on the Transaction end tab and fill in the fields.

You can either choose to:

Use automatic transaction end detection
Untick the automatic option for filling in manual transaction end fields.

Use automatic transaction end detection

To simplify the process transaction end configuration, Nexthink Applications offers automatic detection.

The system enables this feature by default. When you select this option, the rest of the configuration options collapse as they are no longer required.

Nexthink recommends backing up your existing transaction end configuration before proceeding with the automatic transaction end detection.

When editing an existing transaction end, you will lose the current configuration after ticking the checkbox and pressing Done.

Manual transaction end fields

Unticking the automatic transaction end detection option opens the manual tranesaction end fields.

The following table displays the manual transaction end fields and how to define them:

Manual transaction end field

Description

End event name

Choose a name for the start element using any standard safe character combination separated by a space, up to 100 characters long.

End event type

Pick one of the options for the end of the transaction:

Element appears
Element disappears
Element CSS class added
Element CSS class removed

End element CSS selector

Paste the CSS selector of the page element used to end the transaction.

Refer to the CSS selectors section.

End element text pattern (optional)

In addition to the CSS selector, you can narrow down the end element using a text pattern.

Note that the text might exist in multiple languages for some applications.

Select all matching elements

Do not tick the box for this field as it is deprecated and to be removed from Nexthink web interface.

Check for new elements only

Select this option for new elements that are generated with an existing element identifier after the transaction starts.

The system ignores the existing element already present and captures the transaction end.

Editing an existing transaction

Created transactions are listed under the Transactions tab on the application's configuration page:

Hover over an existing transaction to reveal the action menu.
Click on the Edit transaction option to open the Edit transaction windows.

Edits the transaction fields. Refer to Defining the Transaction start and Defining the Transaction end.
Click Done to save changes.

Importing and Exporting a transaction

Under the Transactions tab from the application's configuration page:

To export a transaction, hover over an existing transaction to reveal the action menu.
- Click on the Export transaction option to export the transaction in a JSON file format.
- The file appears in your browser’s downloads folder.
To import a transaction, click the Import transaction button to import a JSON-format transaction file.

Setting CSS selectors for transactions

CSS selectors identify specific elements on web pages. It is crucial to use the appropriate selectors when setting up transactions.

Keep in mind these special considerations:

Selectors can change when the application is updated or upgraded.
Selectors can change when the page is reloaded.
One selector can reference more than one element of the page.

To work around these issues, analyze the following points for each transaction start and end event:

If the application is available in multiple languages, avoid selectors containing text.
Avoid selectors containing randomly generated strings of characters.
Reload the page to make sure that the selector still works after the page reloads.
Explore all page elements to ensure that other elements might not be selected when the page is in a different configuration.
- For example, expanding a combo box or unveiling a hidden menu.
Confirm that the selectors still work when the application gets updated or upgraded.

If Nexthink fails to collect transactions after system maintenance, it may indicate the need for selector adjustment.

You can find the CCS selectors using the following options:

Nexthink browser extension (recommended)
Nexthink toolbox extension
Browser's developer tools

Using the Nexthink browser extension

The Nexthink browser extension lets you detect individual transactions for the monitored web application or domain. The extension significantly simplifies and facilitates the process of setting up transactions by allowing you to:
