Includes information on processes that may have exited while the script was running. The script contains configuration options listed in the script source. $ stap proctop.stp -T 12 5 seconds: showing 25 out of 54 tasks PID Process State VirtMem RSSMem ShrdMem CPU Time User Time 2236 pulseaudio S 643694592 8724480 6864896 7094425000000 2978547000000 1158 Xorg S 223195136 28401664 9035776 5774527000000 4390357000000 12744 qemu-system-x86 S 4969811968 2215833600 7876608 2569998000000 62426178000000 2741 tmux S 143491072 17453056 2449408 1325262000000 2353978000000 9032 firefox S 3280347136 1484169216 77258752 1281250000000 102632316000000 7345 qemu-system-x86 S 4983103488 2269044736 7933952 1225863000000 7366649000000 9145 plugin-containe S 1173696512 121954304 41582592 1129882000000 4464864000000 2633 xchat S 702238720 28114944 15888384 467695000000 2456379000000 24798 xfwm4 S 507027456 13905920 10489856 331524000000 732607000000 2140 xfce4-panel S 598822912 16449536 11145216 187518000000 1842513000000 2131 xfce4-session S 442097664 8134656 6328320 80346000000 133387000000 7 rcu_sched S 0 0 0 52510000000 0 2239 xscreensaver S 199114752 5754880 4874240 48930000000 43000000000 8 rcuos/0 S 0 0 0 42512000000 0 0 swapper/0 R 0 0 0 38474000000 0 846 rngd S 4468736 1282048 1253376 33684000000 69954000000 10 rcuos/2 S 0 0 0 33366000000 0 2389 pool S 654041088 13492224 4538368 29291000000 35436000000 976 NetworkManager S 454553600 6369280 4857856 28305000000 123014000000 7410 vhost-7345 S 4983103488 2269044736 7933952 23621000000 0 869 in:imjournal S 822587392 8859648 8499200 23447000000 13619000000 4284 xfce4-terminal S 778174464 24412160 18997248 23330000000 152980000000 22385 python2 S 2573504512 13864960 7249920 13122000000 61526000000 523 systemd-journal S 111550464 36225024 33824768 12646000000 3644000000 8501 python2 S 2573733888 16203776 7573504 11809000000 55554000000 ----------------------------------------------------------------------------------------------------------------- 10 seconds: showing 25 out of 58 tasks PID Process State VirtMem RSSMem ShrdMem CPU Time User Time 2236 pulseaudio S 643694592 8724480 6864896 7094446000000 2978555000000 1158 Xorg S 223195136 28401664 9035776 5774528000000 4390357000000 12744 qemu-system-x86 S 4969811968 2215833600 7876608 2569998000000 62426178000000 2741 tmux S 143491072 17453056 2449408 1325262000000 2353978000000 9032 firefox S 3280347136 1486053376 77258752 1281262000000 102633852000000 7345 qemu-system-x86 S 4983103488 2269044736 7933952 1225863000000 7366649000000 9145 plugin-containe S 1173696512 121954304 41582592 1129887000000 4464898000000 2633 xchat S 702238720 28114944 15888384 467696000000 2456379000000 1021 wpa_supplicant S 60608512 10592256 4325376 339374000000 32641000000 24798 xfwm4 S 507027456 13905920 10489856 331524000000 732607000000 849 irqbalance S 19599360 2162688 2060288 237728000000 39968000000 2140 xfce4-panel S 598822912 16449536 11145216 187518000000 1842513000000 2131 xfce4-session S 442097664 8134656 6328320 80346000000 133387000000 7 rcu_sched S 0 0 0 52510000000 0 2239 xscreensaver S 199114752 5754880 4874240 48930000000 43000000000 8 rcuos/0 S 0 0 0 42512000000 0 0 swapper/0 R 0 0 0 38474000000 0 846 rngd S 4468736 1282048 1253376 33684000000 69954000000 10 rcuos/2 S 0 0 0 33366000000 0 2389 pool S 654041088 13492224 4538368 29291000000 35436000000 976 NetworkManager S 454553600 6369280 4857856 28305000000 123014000000 7410 vhost-7345 S 4983103488 2269044736 7933952 23621000000 0 869 in:imjournal S 822587392 8859648 8499200 23447000000 13619000000 4284 xfce4-terminal S 778174464 24412160 18997248 23330000000 152980000000 39 khugepaged S 0 0 0 18809000000 0 ----------------------------------------------------------------------------------------------------------------- This is the default configuration of the proctop.stp script. It sorts based on cpu time, and only shows a max of 25 processes. A configuration that might be useful would be to sort by the state to see a short list of the processes that have stopped while the script was running. $ stap proctop.stp -T 12 -G show=5 -G sort=state -G sortby=decrease 5 seconds: showing 5 out of 61 tasks PID Process State VirtMem RSSMem ShrdMem CPU Time User Time 12319 systemd-udevd DEAD 0 0 0 0 0 9032 Timer S 3280166912 1453039616 76521472 1288175000000 104009126000000 12318 stapio S 129527808 860160 782336 18000000 3000000 7 rcu_sched S 0 0 0 52576000000 0 10 rcuos/2 S 0 0 0 33408000000 0 ----------------------------------------------------------------------------------------------------------------- 10 seconds: showing 5 out of 74 tasks PID Process State VirtMem RSSMem ShrdMem CPU Time User Time 12319 systemd-udevd DEAD 0 0 0 0 0 12323 bash DEAD 0 0 0 0 0 12324 git DEAD 0 0 0 1000000 0 12325 bash DEAD 0 0 0 1000000 0 12326 git DEAD 0 0 0 0 0 -----------------------------------------------------------------------------------------------------------------
