> zacatek staci TOP a zjistit, kdo vlastne ma tu pamet na svedomi.
^-- Stale ale narazam na problem, ako udaje zobrazovane v top vlastne
interpretovat. Napr. u mna teraz zobrazuje toto:
last pid: 88929; load averages: 2.51, 2.56, 2.57 up 0+23:00:16 13:57:51
99 processes: 3 running, 95 sleeping, 1 zombie
CPU states: 85.2% user, 0.0% nice, 14.5% system, 0.4% interrupt, 0.0% idle
Mem: 338M Active, 749M Inact, 188M Wired, 53M Cache, 112M Buf, 175M Free
Swap: 1024M Total, 1024M Free
PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND
663 root 1 76 0 174M 136M select 19:02 0.00% Xorg
6894 babjak 4 20 0 108M 84732K kserel 14:46 0.00% firefox-bin

1239 babjak 1 76 0 31560K 18180K select 0:01 0.00% kdeinit
Este zlozitejsie to vidim napr. u Solarisu, kde neviem ani poriadne
dat dohromady udaje z top a prstat. Z toho isteho servera v tej istej
chvili zobrany top:
last pid: 3786; load averages: 0.13, 0.12, 0.11 14:01:50

Co mi pride najdivnejsie, ak spocitam polozky "rss" alebo polozky "size",
dojdem k suctu daleko vyssiemu, ako ram+swap: ten server ma 2GB ram a
-- podla vsetkeho -- 3.1GB swap, aj ked netusim, ako admin prave
k takejto hodnote prisiel. Pricinou moze byt shared memory, ktora
sa zapocitava kazdemu procesu, ktory ju vyuziva; preto tolko pamate
pre oracle.
Ako teda interpretovat udaje zobrazene programom top(1) vo FreeBSD?
Ako ich interpretovat vo vseobecnosti na inych unixovskych systemoch?
