Basic Commands Prerequisite Install Linux kernel header package(s) if you want to collect data using the LiKI DKLM module KI dump collection Examples Online kiinfo Examples KI dump help kiinfo help runki -h kiinfo -h Collect for 60 seconds PID Analysis Report with multiple PID filters for 30 seconds runki -d 60 kiinfo -kipid pid=6814,pid=6815,scdetail -a 30 Collect using ftrace with all events Disk Analysis report to show top 10 pids accessing a specific dev every 5 seconds for a minute runki -f kiinfo -kidsk dev=0x00800010,npid=10 -a 5 -p 12 Collect with Avanced CPU statistics runki -R CPU/RunQ Analysis with Advanced CPU statistics kiinfo -kirunq events=default,msr -a 5 Collect and include scsi subsys Installation: rpm --install --nodeps linuxki-5.7-1.noarch.rpm dpkg --install linuxki_5.7-1_all.deb runki -e default -s scsi Collect with Collect/MW, sar, perf data and Java stacks Add LinuxKI to your PATH variable: export PATH=$PATH:/opt/linuxki cd /dev/shm runki [-d] # if memory is available # default is 20 secs IMPORTANT NOTE: The longer the trace collection, the larger the resulting LinuxKI trace dump. Be sure you have plenty of disk space or space in /dev/shm to collect your LinuxKI trace dump! Post-process KI Dump data kiinfo -kitrace subsys=scsi -a 60 | grep -i synchronize_cache runki -M -U -X -j Collect with all subsystems, excluding some system calls Collect KI Dump: Show just SCSI Synchronize Cache commands for 1 minute echo “time” >sysignore echo “futex” >>sysignore echo “gettimeofday” >>sysignore runki -e all -I sysignore Collect using PID filtering for 2 minutes KI Dump kiinfo Examples PID Analysis Report with System Call details, Cooperating Task details, and per-pid RunQ Histogram kiinfo -kipid scdetail,coop,rqhist -ts 0416_1523 runki -P 26814 -d 120 PID Analysis Report with Time filtering runki -c “slow run, only 30 MB/sec” kiinfo -kipid scdetail -start 3.0 -end 4.0 -ts 0416_1523 KI Dump Post Processing Examples Disk Analysis Report with modify I/O Histogram Collect data and add a comment kiall [-r] Mounting the debug filesystem (debugfs) mount -t debugfs debugfs /sys/kernel/debug Curses-base live mode mount -t debugfs debugfs /sys/kernel/debug kiinfo -live [-a ] # default is 5 secs Clean-up KI files in cwd kiclean -p -v -f Post-processing help kiall -h Create / subdir structure kiall -r Create Visualization charts and graphs kiall -V Create Kparse Report in text format kiall -x Linux KI Quick Reference Guide (v5.7) echo “2 5 10 20 50 100” >bkfname kiinfo -kidsk bkfname=bkfname -ts 0416_1523 Kitrace Report with formatted time and the per-cpu sequence counter for a specific CPU kiinfo -kitrace seqcnt,fmttime,cpu=4 -ts 0416_1523 Kiinfo -live Commands Menu Global Statistics and Select Per-Task Statistics and Selective Statistics Control and Miscellaneous Commands s g l c p h i d m z y t f w u n k G D M L W P F O U - Task Task Task Task Task Task Task Task Task ? r b + - C T I K X - Select Select Select Select Select - Select Global Global Global Global Global Global Global Global Global Global Global Global Global Global Global Global Task/CPU/Disk Task List Node Stats CPU Stats Prof Stats HT CPU Stats IRQ Stats Disk Stats Mpath Stats HBA Stats WWN Stats IO by PID File Stats Wait Stats Futex Stats Socket Stats Docker Stats Main Stats Disk Stats Mpath Stats System Calls Wait Stats Profile Stats File Stats Coop Stats Futex Stats CPU Stats Disk Stats IRQ Stats Docker Stats Futex Stats Linux KI Quick Reference Guide (v5.7) - Help Refresh Prev Screen Show Syscall Detail Hide Syscall Detail Online mode only a - Set Alarm Interval e - Exclude Syscall E - Show Excl Syscalls Dump mode only > - Next Step < - Prev Step j - Step Time J - Jump to Time runki [-h] [-L] [-M] [-U] [-X] [-a] [-j] [-J path] [-f | -p] [-n interface] [-v] [-d duration] [-t maxrun] [-P pid] [-G tgid] [-C cpu] [-D dev] [-R] [-e vent] [-s subsys] [-I sysignore] [-T timestamp] [-c "comment"] -h Help -L Gather minimal data for local analysis...no gzip/tar -M Include Collectl/MeasureWare data collection -U Include userspace profile (perf) data collection -X Include sar data collection -a Execute 'perf annotate' on userspace profile (perf) data -j Collect Java stacks -J Location of Java jstack command -n Gather tcpdump trace data -v Skip vxfs, misc disc data collection -d Duration of KI data collection. Defaults to 20 secs if not specified. -t Maximum time for data collection tools to run.
