| + | == Memory Usage Collector Install Steps == | ||
| + | |||
| + | * Install sp-smaps | ||
| + | ** wget http://repo.pub.meego.com/home:/timoph/Project_DE_Trunk_Testing_standard/armv7hl/sp-smaps-0.3.0-3.2.DE.armv7hl.rpm | ||
| + | ** rpm -Uvh sp-smaps-0.3.0-3.2.DE.armv7hl.rpm | ||
| + | * Copy/Paste from below the /usr/bin/memusage.sh script to Meego (remember to do: chmod a+x /usr/bin/memusage.sh) | ||
| + | * Edit /etc/rc.sysinit so that /usr/bin/memusage.sh is launched 120 sec after boot automatically | ||
| + | * Reboot --> Data should be available after 120 sec in /home/meego/memusage dir | ||
| + | ** html file for smaps findings | ||
| + | ** txt file for data generated by other mem tools | ||
| + | *** Especially "ps -e -orss=,args= | sort -b -k1,1n | pr -TW100" data from top memory usager processes is interesting | ||
