How to view CPU-consuming processes in aix

How to view CPU-consuming processes in aix first check who has the largest CPU usage: display the first 10 processes that have accumulated CPU usage # ps-e | head-n 1; ps-e | grep-v "TIME | 0: "| sort + 2b-3-n-r | head-n 10 displays the first 10 processes that currently occupy CPU time # ps-ef | head-n 1; ps-ef | grep-v "C | 0: 00" | sort + 3b-4-n-r | head-n 10 Aix command: list the first few processes using memory and Cpu (1) display 10 processes that consume the most cpu # ps aux | head-1; ps aux | sort-rn + 2 | head-10 (2) displays 10 processes that consume the most memory # ps vx | head-1; ps vx | grep-v PID | sort-rn + 6 | head-10 (3) processes with the largest number of page breaks # ps vx | head-1; Ps vx | grep-v PID | sort-rn + 4 | head-10 (4) displays 10 processes that consume the most storage space # ps aux | head-1; ps aux | sort-rn + 3 | how does head-10 monitor the memory usage of processes (AIX) There are many tools for AIX to monitor the memory usage of processes? In my opinion, nmon is a convenient tool, svmon, in which svmon is an AIX tool that requires root permission for execution. It can monitor detailed memory usage information of processes, such as svmon-P pid (process PID to be monitored) -I 1 (refresh once per second) | process memory Analysis in grep pid AIX the ps v tool or svmon tool can be used in AIX to analyze process memory. Ps v command is a tool of ps command. Note that "-" is not added before v. The ps v tool can be used in any AIX operating system. For example: # ps-lfp 13288 f s uid pid ppid c pri ni addr sz wchan stime tty time cmd 240001 A oracle 13288 1 0 60 20 1ba2f 34032 Nov 03-0: 06ora_pmon_DEV # ps v 13288 pid tty stat time pgin size rss lim tsiz trs % CPU % mem command 13288-A 0:08 225 5616 13904 32768 28420 13512 0.0 1.0ora _ pmon_DEV from ps COMMAND to see sz is 34 M. The ps v command shows that rss is 13904 and TRS is 13512. The memory used by the process is RSS-TRS = 392 K (ps v sees the memory unit is K ). Svmon can be used to view more information. The result is consistent with ps v. For example: # svmon-P 23288 running Pid Command Inuse Pin Pgsp Virtual 64-bit Mthrd 23288 ora_pmon_V8 29598 1451 182 16560 N Vsid Esid Type Description Inuse Pin Pgsp Virtual AddrRange 1781 3 work shmat/mmap 11824 0 0 118240 .. 24700 1761 1 pers code, large file/dev 9681 0--0 .. 9680 0 0 work kernel seg 3982 1450 182 33900 .. 21804: 65474 .. 65535 18018 d work shared library text 2852 0 0 1580 .. 65535 4764 2 work process private 1127 1 0 1127 these command combinations are helpful for managing the RS/6000 AIX system: (1) display 10 processes that consume the most CPU: # ps aux | head-1; ps aux | sort-rn + 2 | head-10 (2) displays 10 processes that consume the most storage space: # ps aux | head-1; ps aux | sort-rn + 3 | head-10 (3) displays the penalty processes in the system in sequence: # ps-eakl | head-1; ps-eakl | sort-rn + 5 (4) display processes in the system in priority order: # ps-eakl | sort-n + 6 | head (5) display the first 10 processes in the system in the order of processing time: # ps vx | head-1; ps vx | grep-v PID | sort-rn + 3 | head-10 (6) display the first 10 processes in the system in the order of actual memory usage: # ps vx | head-1; ps vx | grep-v PID | sort-rn + 6 | head-10 (7) display the first 10 processes in the system in the order displayed on the switch-in page: # ps vx | head-1; ps vx | grep-v PID | sort-rn + 4 | head-10
