计算性能摘要日志的最大和最小执行时间:

日志摘要：

 

st,Y,10000ms,DDD
st,N,10ms,EEE
o,Y,30000000ms,EEE
b,N,399ms,dd
c,Y,400ms,mm
d,N,20000ms,aa
eee,N,388ms,NNN

 

统计成功情况：

 

awk -F , 'BEGIN {min=10000000;max=-1;} /,Y,/ {span=substr($3,0,length($3)-2)+0;if(min > span){min = span;min_row=$0}; if(max < span){max=span;max_row=$0};} END {print "Min Time:",min_row;print "Max Time:",max_row}' test.log 

 

统计失败情况：

 

awk -F , 'BEGIN {min=10000000;max=-1;} /,N,/ {span=substr($3,0,length($3)-2)+0;if(min > span){min = span;min_row=$0}; if(max < span){max=span;max_row=$0};} END {print "Min Time:",min_row;print "Max Time:",max_row}' test.log 

 

 

结果 ：

Min Time: c,Y,400ms,mm
Max Time: o,Y,30000000ms,EEE
