![]() A monitored machine groups together several Monitors. A monitored machine may be a physical machine or a network device. Monitored machineĪ monitored machine is a server, or other device in the infrastructure, that is to be monitored. A Monitor groups together several performance counters and indicators. MonitorĪ Monitor observes the behavior of a component part of a monitored machine (web server, application server, operating system, database, etc.). It helps determine if the application works fine with the loads that result from large numbers of simultaneous users, transactions and to determine whether it can handle peak usage periods. Load testing consists in simulating real-life workload conditions for the tested web application. Load Generator may refer either to the program simulating the users, or to the machine on which it is installed. NeoLoad Web has an agent and Load Generator built in for ease of use. A Load Generator is started by its Load Generator Agent for each User Path validation. The Load Generator is a program piloted by the Controller, which plays a scenario while simulating a predefined number of users. The HTTP response is the Web server answer to an HTTP request. Requests are the messages sent by the client to a server which emits a response HTTP response ![]() The HTTP request is the request sent to the server to retrieve an HTML page, image or CSS file. If the element is interrupted (because of error or end of test), then the count number is not incremented. CountĬount statistics are the number of full executions of an element of a User Path. Other than clearly pointing out unexpected or faulty behavior in load scenarios, assertions and assertion errors also reveal functional issues. NeoLoad and NeoLoad Design Studio can be configured to throw assertion errors when the conditions defined by an assertion are not met. Validation can be based on the response content, size or duration. Validates a server response during a test by defining and asserting a condition that must be met.
