What is each column?
man vmstat?
In one sense all manual pages are; reading them is an acquired skill. (Writing them is also a skill!)
It is certainly a skill. This particular one is better written than others. There are some that takes me months to understand, so fearing that, I asked.
Swap si: Amount of memory swapped in from disk (/s). so: Amount of memory swapped to disk (/s).
I'd prefer read/write
How is that not read/write?
I mean that to me, r/w is easier.
IO bi: Blocks received from a block device (blocks/s). bo: Blocks sent to a block device (blocks/s).
What's a block? Maybe 1KiB.
How is you system set up? What's a disk block? Is it 4K or ore you still on 512byte disk blocks?
There may be both, depending on the age of each disk. Tha manual says that it is 1KiB on all modern kernels, though.
CPU These are percentages of total CPU time. us: Time spent running non-kernel code. (user time, including nice time) sy: Time spent running kernel code. (system time) id: Time spent idle. Prior to Linux 2.5.41, this includes IO-wait time. wa: Time spent waiting for IO. Prior to Linux 2.5.41, included in idle. st: Time stolen from a virtual machine. Prior to Linux 2.6.11, unknown
stolen? what is that?
Since I don't run a virtual machine I don't know. I suspect it has to do it you run this ON a virtual machine.
I do run virtual machines some times, and I have never seen this concept. Any way, now it shows: procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu----- r b swpd free inact active si so bi bo in cs us sy id wa st 3 0 2329 19751 1637 9508 0 0 45 133 3620 6020 71 8 0 20 0 0 0 2329 19790 1637 9468 0 0 0 112 3568 6004 87 10 0 3 0 1 1 2329 19706 1637 9552 0 0 33 128 3243 5820 81 13 0 6 0 3 0 2329 19683 1637 9578 0 0 4 38 3267 5645 87 9 0 4 0 0 0 2329 19644 1637 9615 0 0 0 102 3240 5419 86 10 0 4 0 0 0 2329 19252 1910 9725 0 0 20092 269 4013 6954 49 8 0 42 0 0 0 2328 19250 1912 9731 0 0 171 185 3169 5506 66 7 0 27 0 1 0 2328 19277 1912 9706 0 0 0 97 3267 5490 85 9 0 6 0 4 0 2328 19287 1679 9930 0 0 49 127 3278 5681 69 10 0 22 0 3 0 2328 19251 1698 9943 0 0 33 1589 3545 6133 62 10 0 28 0 2 0 2327 19290 1698 9904 0 0 74 46 3360 5696 72 8 0 20 0 top - 14:02:56 up 4 days, 13:10, 2 users, load average: 0,60, 0,65, 0,53 Tasks: 551 total, 2 running, 548 sleeping, 0 stopped, 1 zombie %Cpu(s): 2,0 us, 0,3 sy, 0,0 ni, 97,5 id, 0,1 wa, 0,0 hi, 0,0 si, 0,0 st KiB Mem : 32876712 total, 18335128 free, 10401488 used, 4140096 buff/cache KiB Swap: 10485760+total, 10257641+free, 2281184 used. 20870552 avail Mem PID USER PR NI VIRT RES SHR SWAP S %CPU %MEM TIME+ COMMAND CODE DATA nMaj vMj vMn RSan RSfd RSlk 24710 cer 20 0 4430776 0,980g 85640 0 S 0,000 3,126 20:18.60 thunderbird-bin 212 1617252 377 0 0 942068 59760 0 11496 cer 20 0 4843260 872956 312428 64460 S 2,388 2,655 86:40.71 firefox 212 912816 5276 0 0 560528 59052 0 11845 cer 20 0 4071616 784796 95820 37160 S 0,000 2,387 11:57.00 Web Content 212 1161692 375 0 3 688976 55692 0 11976 cer 20 0 3977680 585980 86052 64712 S 0,597 1,782 168:09.69 Web Content 212 1028908 4925 0 123 499928 60132 0 20464 cer 20 0 4401012 584172 179544 0 S 0,000 1,777 19:17.50 firefox 212 729260 209 0 0 404628 55656 0 20628 cer 20 0 3577652 512744 202828 0 S 0,896 1,560 43:35.84 Web Content 212 554964 2 0 1k 309916 54028 0 11911 cer 20 0 3830272 473816 115144 4848 S 0,000 1,441 13:06.18 Web Content 212 802968 1146 0 0 358672 60896 0 11794 cer 20 0 3749636 465324 93140 5312 S 0,000 1,415 13:12.27 Web Content 212 757192 1515 0 0 372184 61308 0 3813 vscan 20 0 1168052 449440 3112 502912 S 0,000 1,367 2:08.61 clamd 180 995972 880k 0 0 446328 3112 0 - -- Cheers, Carlos E.
