Performance Tests

Apache JMeter was the testing tool used for analyzing and measuring the performance of the MDA component. This tool simulates a group of tenants sending requests to a target server, and returns statistics that show the functionality of the target server/application via tables. For performance purposes, the dynamic features were the number of monitoring specs, the monitored metrics, and finally the number of active threads running/listening on our system. Next, we display those tests, divided by scenarios, and their corresponding results:

• Scenario A: increase the number of metrics inside a certain monitoring spec
• Scenario B: increase the number of monitoring specs with a set number of metrics
