The best way is to use the processor ROMs (CTRL-B on the console) and choose whether you want to simply force a reboot or actually create a crashdump on the test system. On the network, the effect is identical--the machine simply stops responding. Since it sounds like the measurement tool is looking at several systems (most likely from the network), you don't need to create a panic condition, just pull out the LAN cable.
Now if the measurement tool actually runs on the target system, note that all system crashes (for *any* OS) halt everything, and nothing (repeat: nothing) will be logged because the system has crashed. For HP-UX, a detected panic condition (versus a CPU failure or power failure) will start a crash dump based in the processor ROMs. Once complete, the system reboots and the savecrash startup script will see if the designated dump area has a new crash dump. If so, the time stamp of the crash is saved in /etc/shutdownlog, the only record of the crash. So the measurement tool won't be able to report anything until after the system reboots if it resides on the affected system.
