HP-UX supplies many tools to help monitor performance, some of which are described as follows:
The sar command reports relative and absolute I/O throughput rates to each disk and controller.
The vmstat command monitors virtual memory usage.
The netstat command monitors network status.
The ps command provides a snapshot of accumulated CPU time and usage for individual processes.
The time command can be useful in determining the various user, system, and real-time resources used over a complete run.
For details about these tools, see your operating system documentation.
