In-Depth Information
You'll need metrics to monitor e.g how many requests get
through to the web servers, and how many requests can
squeeze through per second before users start getting a
response time of over two seconds. You will have to monitor
RAM, CPU and disk usage to make sure that the load
balancer can handle the connections. might need to review
web server log files, start performance counters, or rely on the
reporting ability of your stress test tool. Aspects required to
be monitored:
• CPU usage
• RAM usage
• Disk usage
• Disk latency
• Network utilization
You might also choose to look at SQL deadlocks, seek times,
etc depending on what you're specifically testing.
Step III: Add User Load
Simulate a test load. There are plenty of tools that can do this,
with configurable options:
• JMeter (Web)
• Apache Benchmark (Web)
• Grinder (Web)
