Try "sar" from the package sysstat. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Alexandre Vieira Sent: Friday, 6 February 2009 5:34 a.m. To: redhat-list@xxxxxxxxxx Subject: Kernel statistic counters Hi list, I'm auditing (dimensioning, security, stability, performance, etc) a platform consisting of 4 RHEL machines and I'm having a hard time finding some system statistics. I'm used to Solaris where you have the kstats counters with basically everything. On linux I see that "ethtool -S ethX" gives me what I need for network stats. How about history counters on CPU activity, memory activity, disk activity? Imagine I want to see sd0 disk error statistic: #kstat sderr:0 module: sderr instance: 0 name: sd0,err class: device_error crtime 42.406513208 Device Not Ready 0 Hard Errors 0 Illegal Request 0 Media Error 0 No Device 0 Predictive Failure Analysis 0 Product MAT3073N SUN72G Recoverable 0 Revision 0602 Serial No 0530B093ML Size 73400057856 snaptime 59275843.5048492 Soft Errors 0 Transport Errors 0 Vendor FUJITSU Or partition 0 (/) from sd0 disk activity: #kstat sd:0:sd0,a module: sd instance: 0 name: sd0,a class: partition crtime 42.500566541 nread 408078787784 nwritten 770591441920 rcnt 0 reads 56436484 rlastupdate 59275924.4385759 rlentime 481828.942334242 rtime 331623.611754405 snaptime 59275924.4385759 wcnt 0 wlastupdate 59275924.4385759 wlentime 990.922349888 writes 35321509 wtime 973.857852654 Much appreciated for your time.
