I was just approached with a project involving server validation testing with reporting on power consumption and BTU/cooling. This is not my area of expertise. Open Source (read: free) is preferable. What tools should I look at using for this process?It seems like I need a two fork solution, one for load testing applications and another for hardware monitoring and reporting.Application Load Testing: The client currently uses Loadrunner for application load generation. I'm guessing that I can simulate usage via a number of different tools once I get more information on the requirements. Most likely something like JMeter or Locust.Performance Monitoring: My thought is that I can use a simple performance monitoring tool to track hardware sensors via SNMP and then generate reports. I've never reported on cooling requirements, but my guess is that I would just convert Watts to BTU to determine the cooling required.
