Advanced Server Analysis™ Module for Linux
Operating System Monitoring
These add-on modules for Web Performance Load Tester™ track the major operating system performance areas: CPU usage, memory, disk I/O, and network for various flavors of Linux. About 23 statistics are automatically collected and the values automatically integrated into load testing/performance reports. The top six most-important parameters are then analyzed, the problem areas are flagged, and advice is provided on what the performance should be under normal circumstances. We've taken great pains to normalize the metrics coming off of each system to better provide a direct comparison between multiple computers in your rig that may be running different operating systems.
Customizable Live and Print Views
| The reports can be viewed from either inside the GUI or output for view in a browser or for printing. The statistics included can be customized so that you only see the sections of the report you want, and only the statistics that are of interest. |
