不同进程log占有量分析
如果中某个进程打印太多log，也会影响系统同性能和monkey煲机成功率。下文是针对具体进程log输出量统计，可以直观的了解到不同进程log输出情况。
获取不同级别TAG的行数和占用字节数
awk '{tag[$3]++;use[$3]+=length($0)} END{for(i in use) print use[i],tag[i],i}' android.log | sed 's:\([0-9]*.*[0-9].*[a-zA-Z]\).*[(].*:\1:g;s:\(.*\)[@].*:\1:g' | awk '{tag[$3]+=$2;use[$3]+=$1} END{for(i in use) print use[i],tag[i],i}' | sort -h -k 1 > result00.txt
