One of my summaries scripts produces this: begin=3D1648245843 end=3D1648246023 Total ops for 180 seconds base dir Operations IOPs IOPS% Bandwidth bandwidth% /nas-1-0/abcdefg/home/user99/.schrodinger 7358 40.88 2.30% 0= =20=20=20=20 0.00% /scratch/carsXY.Z9_rsm#z1-14-0-3e/fort.50 4312 23.96 1.35% 1832394= =20=20=20=20 1.68% /scratch/carsXY.Z9_rsm#z8-77-0-99/fort.50 4103 22.79 1.28% 2376893= =20=20=20=20 2.18% hosts: Operations 192.168.6.55:31235 37529 11.74% 192.168.5.51:17155 10623 3.32% 192.168.13.28:9219 6981 2.18% 192.168.6.15:57603 6973 2.18% Operations nfsd.proc4.write 146374 45.77% nfsd.proc4.read 123553 38.64% nfsd.proc4.lookup 20517 6.42% nfsd.proc4.commit 19071 5.96% nfsd.proc4.remove 7566 2.37% nfsd.proc4.rename 2486 0.78% nfsd.proc4.create 223 0.07% I find it great for finding weird behavior, like say the above mentioned fi= le that's using zero bandwidth, but 40% of the OPS, turns out nearly all are nfsd.proc4.lookup. Another common problem is this weird issue where c++ programs seek to X, write 4 byte, seek to X write 8 bytes, seek to X and wr= ite 12 bytes .... 4096 bytes, then seek to X+4096. So only 1 in 1024 writes are actually kept. Do scripts like this seem generally useful? --=20 You are receiving this mail because: You are the assignee for the bug.=
