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

Much appreciated for your time.
