第二、 命令参数
# topas -h
Usage: topas [-d number_of_monitored_hot_disks]
[-h show help information]
[-i monitoring_interval_in_seconds]
[-m Use monochrome mode - no colors]
[-n number_of_monitored_hot_network_interfaces]
[-p number_of_monitored_hot_processes]
[-w number_of_monitored_hot_WLM classes]
[-c number_of_monitored_hot_CPUs]
[-P show full-screen Process Display]
[-L show full-screen Logical Partition display]
[-U username - show username owned processes with -P]
[-W show full-screen WLM Display]
整个命令都比较简单。并且这些参数都可以作为子命令,在运作情况下直接按相应键来完成显示的却换。
例子:
# topas -d1 -c0 -p3
但是试验发现在非全屏(P参数)下,指定p参数并没有任何效果,只有在单独显示处理器的情况下才有效。
