我有以下结果/ stat文件来自运行我想用awk分析的测试:
$date $time $statname $traffic_rate $val1 $val2
20140909 132920326 stat1 30/sec 40 80
20140909 132950326 stat1 29/sec 60 20
20140909 133020326 stat1 28/sec 70 100
20140909 133050326 stat1 0/sec 0 0
20140909 133120326 stat1 0/sec 0 0
20140909 133150326 stat1 30/sec 90 50
$time
采用以下格式:HHMMSSmmm
,并以30秒为间隔生成统计信息。我需要为每个具有$ traffic_rate值> =' 28 /秒'的连续统计信息平均$val
和$val2
值。使用traffic_rate<忽略统计信息28 /秒并重复下一个系列的过程> = 28 /秒等等。
我想使用bash脚本,并认为awk将是分析列数据的不错选择。为了将连续时间戳与$ traffic_rate> = 28 /秒进行比较,我需要使用mktime转换$ time。但是,由于没有分隔符,我无法分割$ time。有没有办法按像PHP中的字符计数分割?
示例输出如下:
test# $val $val2
1 170/3 200/3
2 90/1 50/1
也就是说,每个连续的> = 28 /秒是单个测试结果,应该单独计算。
此外,任何其他建议分析这些类型的模式将不胜感激。感谢。

使用awk
:
awk -v OFS="\t" '
BEGIN { print "test#", "$val", "$val2" }
$4 == "0/sec" && count {
print ++id, val1/count, val2/count
count = val1 = val2 = 0
}
$4+0>=28 && NR>1 {
val1+=$5
val2+=$6
++count
}
END {
print ++id, val1/count, val2/count
}' file
test# $val $val2
1 56.6667 66.6667
2 90 50

如果val1
每30秒一次,您可以使用平均val2
traffic_rate
的简短脚本来完成您的需求:
#!/bin/bash
## validate data file input
[ -f "$1" ] || {
printf "\nError: insufficient input. File '%s' not found.\n\n" "${0//\//}"
exit 1
}
declare -i cnt=0 # simple count variable
printf "\n val1 val2\n\n" # print generic header
## read each line in file
while read -r dt tm sn trf v1 v2 || [ -n "$dt" ]; do
trf=${trf%/*} # extract numeric traffic_rate
if [ "$trf" = 30 ]; then # if equal to 30
v1a+=( $v1 ) # add values to v1 array and v2 array
v2a+=( $v2 )
((cnt++))
else
v1s=0 # reset v1 sum and v2 sum
v2s=0
for i in ${v1a[@]}; do v1s=$((v1s+i)); done # calculate v1 sum from v1 array
for i in ${v2a[@]}; do v2s=$((v2s+i)); done # calculate v2 sum from v2 array
if [ $v1s -gt 0 ] && [ $v2s -gt 0 ]; then # if both greater than 0, output
printf " %6s %6s\n" \
$( echo "scale=2; $v1s/$cnt" | bc ) $( echo "scale=2; $v2s/$cnt" | bc )
fi
cnt=0
unset v1a v2a
fi
done <"$1"
## output if array elements remain
if [ ${#v1a[@]} -gt 0 ]; then
v1s=0
v2s=0
for i in ${v1a[@]}; do v1s=$((v1s+i)); done
for i in ${v2a[@]}; do v2s=$((v2s+i)); done
if [ $v1s -gt 0 ] && [ $v2s -gt 0 ]; then
printf " %6s %6s\n" \
$( echo "scale=2; $v1s/$cnt" | bc ) $( echo "scale=2; $v2s/$cnt" | bc )
fi
cnt=0
unset v1a v2a
fi
printf "\n"
exit 0
