Introduction

Qlik Sense is a powerful business intelligence tool that can help organizations make informed decisions. It allows users to connect to various data sources and create interactive visualizations, dashboards, and reports. However, the success of Qlik Sense largely depends on the accuracy and reliability of the data it processes. One of the critical factors that impact the data quality is the connectivity between the Qlik Sense server and the data source. To ensure that the connectivity is stable and secure, Qlik Sense provides a WebSocket Connectivity Tester. In this article, we will delve into the details of this tool and explore its features, benefits, and limitations.

What is Qlik Sense Websocket Connectivity Tester?

WebSocket Connectivity Tester is a utility provided by Qlik Sense that enables users to test the WebSocket connection between the Qlik Sense server and the data source. WebSocket is a communication protocol that allows bidirectional communication between a client and a server over a single TCP connection. It is commonly used in web applications to provide real-time data updates. In Qlik Sense, WebSocket is used to transfer data between the server and the client, such as selections, bookmarks, and app objects.

Why is WebSocket Connectivity Important?

The WebSocket connection plays a vital role in the performance and reliability of Qlik Sense. If the WebSocket connection is unstable or insecure, it can lead to various issues such as slow data loading, incomplete data retrieval, or even data loss. Therefore, it is essential to ensure that the WebSocket connection is properly configured and tested before deploying Qlik Sense in a production environment.

How Does WebSocket Connectivity Tester Work?

The WebSocket Connectivity Tester is a command-line tool that can be run on the Qlik Sense server or any other machine that has network access to the server. It sends WebSocket messages to the Qlik Sense server and waits for a response. If the response is received within the specified time limit, the connection is considered successful. Otherwise, the connection is considered failed, and the tool provides information on the cause of the failure.

Features of WebSocket Connectivity Tester

Easy to Use: WebSocket Connectivity Tester is a simple and straightforward tool that does not require any technical expertise. It can be run from the command line, and the output is displayed in a user-friendly format.
Customizable: WebSocket Connectivity Tester allows users to customize the test parameters, such as the message payload, timeout, and number of retries. This enables users to simulate different scenarios and test the WebSocket connection under various conditions.
Comprehensive: WebSocket Connectivity Tester provides detailed information on the test results, including the response time, message size, and error messages. This helps users diagnose and troubleshoot any issues with the WebSocket connection.
Scalable: WebSocket Connectivity Tester can be used to test the WebSocket connection for multiple Qlik Sense servers simultaneously. This makes it ideal for large-scale deployments where multiple servers are involved.
Secure: WebSocket Connectivity Tester supports secure WebSocket connections using SSL/TLS encryption. This ensures that the data transferred between the server and the client is protected from unauthorized access or interception.

Limitations of WebSocket Connectivity Tester

Although WebSocket Connectivity Tester is a useful tool for testing the WebSocket connection, it has some limitations that users should be aware of:

Not a Monitoring Tool: WebSocket Connectivity Tester is designed to test the initial WebSocket connection between the server and the client. It does not provide continuous monitoring of the connection or alert users when the connection is lost.
Requires Technical Knowledge: Although WebSocket Connectivity Tester is easy to use, it still requires some technical knowledge to interpret the test results and diagnose any issues with the WebSocket connection.
Does Not Test Data Transfer: WebSocket Connectivity Tester only tests the WebSocket connection and does not verify that data can be transferred successfully between the server and the client. Therefore, users should also test the data transfer separately to ensure the accuracy and completeness of the data.
