linux進程記憶體佔用排序命令

linux進程記憶體佔用排序命令 今天查看linux伺服器，想查看各個進程的佔用率，就使用： [qhkf@116share ~]$ top PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND29613 build 15 0 158m 7136 3720 S 2.0 0.1 0:00.27 svn29609 build 15 0 158m 7132 3720 S 2.3 0.1 0:00.70 svn29601 qhkf 15 0 12868 1260 820 R 0.3 0.0 0:00.09 top29598 oracle 15 0 1935m 15m 13m S 0.0 0.2 0:00.00 oracle29596 oracle 15 0 1936m 27m 24m S 0.0 0.3 0:00.03 oracle29582 qhkf 15 0 102m 3420 2252 S 0.0 0.0 0:00.04 vim29506 build 15 0 158m 7252 3724 S 2.3 0.1 0:03.76 svn但是沒有按照記憶體排序，然後查了下，按一下shift + f 就可以出現排序的列 Current Sort Field: N for window 1:DefSelect sort field via field letter, type any other key to return   a: PID = Process Id shown due to screen width or your  b: PPID = Parent Process Pid field order, the '<' and '>' keys  c: RUSER = Real user name will be unavailable until a field  d: UID = User Id within viewable range is chosen.  e: USER = User Name  f: GROUP = Group Name Note2:  g: TTY = Controlling Tty Field sorting uses internal values,  h: PR = Priority not those in column display. Thus,  i: NI = Nice value the TTY & WCHAN fields will violate  j: P = Last used cpu (SMP) strict ASCII collating sequence.  k: %CPU = CPU usage (shame on you if WCHAN is chosen)  l: TIME = CPU Time  m: TIME+ = CPU Time, hundredths* N: %MEM = Memory usage (RES)  o: VIRT = Virtual Image (kb)  p: SWAP = Swapped size (kb)  q: RES = Resident size (kb)  r: CODE = Code size (kb)  s: DATA = Data+Stack size (kb)  t: SHR = Shared Mem size (kb)  u: nFLT = Page Fault count  v: nDRT = Dirty Pages count  w: S = Process Status  x: COMMAND = Command name/line  y: WCHAN = Sleeping in Function  z: Flags = Task Flags <sched.h>然後就可以選擇自己喜歡的排序方式啦，例如選擇N，看看那幾個進程佔用的記憶體大，接下來就可以分析啦 PID   USER   PR NI VIRT RES SHR   S %CPU%MEM TIME+  COMMAND14101 oracle 15 0 1941m 613m 608m S 0.0 7.7 2:25.78 oracle14095 oracle 15 0 1987m 521m 477m S 0.0 6.5 2:24.58 oracle20477 oracle 15 0 1945m 483m 478m S 0.0 6.1 0:24.79 oracle14522 oracle 15 0 1941m 427m 420m S 0.0 5.4 2:20.59 oracle14105 oracle 15 0 1941m 268m 262m S 0.0 3.4 3:46.04 oracle
