For High CPU Utilization Process

ps -eo pcpu,pid,user,args | sort -k1 -r | head -10

ps -eo pcpu,pid,user,args | sort -k 1 -r | head -10


For Used Memory

free | awk 'FNR == 3 {print $3/($3+$4)*100}'

free -m|awk 'FNR == 2 {print $3*100/$2}'


For Free memory

free | awk 'FNR == 3 {print $4/($3+$4)*100}'


For High Memmory Utilization Process

ps aux --sort -rss | head


For avarage load on Server

uptime | sed 's/.*load average: //'


For Zomebee process

ps axo stat,ppid,pid,comm | grep -w defunct

ps aux --sort -rss| grep -w defunct

ps aux | grep 'Z'

For strace PID

strace -p PID -o output.file

For Sleeping process list

ps -eo pid,cmd,etime | sort -k 1 -r | head -10


For Only Cpu Utilization

mpstat 1 1 | awk '$3 ~ /CPU/ { for(i=1;i<=NF;i++) { if ($i ~ /%idle/) field=i } } $3 ~ /all/ { printf("%d",100 - $field) }'
