locust:tldr:a1ba3

This command is used to start Locust, which is an open-source load testing tool. Locust simulates users (known as "swarm") that interact with a target website or system, generating a specified number of requests per second to test its performance under heavy loads.

Here's the breakdown of the command:

• "locust" is the command to start the Locust load testing tool.
• "--master" specifies that this instance of Locust will act as the master node in a distributed load testing setup. The master node is responsible for coordinating and aggregating results from slave nodes.
• "--host=${http:--example-com}" sets the target host that Locust will test. This syntax uses environment variables to define the target host URL. In this case, the host URL is set to "http://example.com". The "--host" flag is used to specify the base URL or host where the Load Test will take place.

To customize the target host URL, you can modify the value after the "--host=" part of the command. For example, "--host=http://mywebsite.com" would set the target host to "http://mywebsite.com".
