在Windows for ASP中,你可以得到它perfmon,但是......
如何在Linux中获取“每秒请求数”?
答案 0 :(得分:25)
这是一个简短的bash脚本,用于对请求率进行采样(基于日志文件中使用wc -l
的{{3}})。
#!/bin/sh
##############################################################################
# This script will monitor the number of lines in a log file to determine the
# number of requests per second.
#
# Example usage:
# reqs-per-sec -f 15 -i /var/www/http/access.log

usage="Usage: `basename $0` -f <frequency in seconds, min 1, default 60> -l <log file>"
# Set up options
while getopts ":l:f:" options; do
case $options in
l ) logFile=$OPTARG;;
f ) frequency=$OPTARG;;
\? ) echo -e $usage
exit 1;;
* ) echo -e $usage
exit 1;;
esac
done
# Test for logFile
if [ ! -n "$logFile" ]
then
echo -e $usage
exit 1
fi
# Test for frequency
if [ ! -n "$frequency" ]
then
frequency=60
fi
# Test that frequency is an integer
if [ $frequency -eq $frequency 2> /dev/null ]
then
:
else
echo -e $usage
exit 3
fi
# Test that frequency is an integer
if [ $frequency -lt 1 ]
then
echo -e $usage
exit 3
fi
if [ ! -e "$logFile" ]
then
echo "$logFile does not exist."
echo
echo -e $usage
exit 2
fi
lastCount=`wc -l $logFile | sed 's/\([0-9]*\).*/\1/'`
while true
do
newCount=`wc -l $logFile | sed 's/\([0-9]*\).*/\1/'`
diff=$(( newCount - lastCount ))
rate=$(echo "$diff / $frequency" |bc -l)
echo $rate
lastCount=$newCount
sleep $frequency
done

实时,或者您可以使用mod_status吗?
显然,有top for apache的版本......
答案 2 :(得分:9)
总而言之,您可以使用mod_status和apachetop。
或者,您可以使用Adam Franco和Jon Daniel的漂亮脚本来实时观看。
如果您想查看一个临时日期和小时,可以发出以下命令:
grep "29/Oct/2014:12" /var/log/apache2/example.com.log | cut -d[ -f2 | cut -d] -f1 | awk -F: '{print $2":"$3}' | sort -nk1 -nk2 | uniq -c | awk '{ if ($1 > 10) print $0}'
替换为您感兴趣的日期和小时,并使用日志文件的正确路径名。替换。
它将打印出类似的内容:
1913 12:47
226 12:48
554 12:49
918 12:50
有一篇很好的文章here,其中有更多选项可以使用awk,cut和uniq命令组合来快速获取此类数据。
答案 3 :(得分:5)
您可以在访问日志中使用'wc -l'来获取行数(大致对应于请求数...)。每分钟执行一次并减去最后一个值以获取delta ...
答案 4 :(得分:3)
我认为mod_status可以做到......
http://httpd.apache.org/docs/2.0/mod/mod_status.html
您还可以使用zenoss使用社区apache插件从mod_status收集数据。
答案 5 :(得分:3)
脚本显示不一致的数字。 -f
参数会影响输出很多!一读也不准确。
我最终使用了:
while true; do tail -n0 -f access.log>/tmp/tmp.log & sleep 2; kill $! ; wc -l /tmp/tmp.log | cut -c-2; done 2>/dev/null
找到here。
答案 6 :(得分:3)
我不喜欢我找到的任何解决方案,所以我自己写了。
因此,此解决方案在access_log 15000请求之前采用特定行,并使用记录的时间与当前时间进行比较。
# This check is needed because if the logs have just rolled over, then we need a minimum
# amount of data to report on.
# You will probably need to adjust the 3500000 - this is roughly the file size when the
# log file hits 15000 requests.
FILESIZE=`ls -l /var/log/httpd/access_log | awk '{print $5}' `
if [ $FILESIZE -le 3500000 ]
then
# not enough data - log file has rolled over
echo "APACHE_RPS|0"
else
# Based on 15000 requests. Depending on the location of the date field in
# your apache log file you may need to adjust the ...substr($5... bit
LASTTIME=`tail -15000 /var/log/httpd/access_log | head -1 | awk '{printf("%s\n",substr($5,2,20));}' `
APACHE_RPS=`echo $LASTTIME | gawk -vREQUESTS=15000 ' {
# convert apache datestring into time format accepted by mktime();
monthstr = substr($0,4,3);
if(monthstr == "Jan"){ monthint = "01"; }
if(monthstr == "Feb"){ monthint = "02"; }
if(monthstr == "Mar"){ monthint = "03"; }
if(monthstr == "Apr"){ monthint = "04"; }
if(monthstr == "May"){ monthint = "05"; }
if(monthstr == "Jun"){ monthint = "06"; }
if(monthstr == "Jul"){ monthint = "07"; }
if(monthstr == "Aug"){ monthint = "08"; }
if(monthstr == "Sep"){ monthint = "09"; }
if(monthstr == "Oct"){ monthint = "10"; }
if(monthstr == "Nov"){ monthint = "11"; }
if(monthstr == "Dec"){ monthint = "12"; }
mktimeformat=sprintf("%s %s %s %s %s %s [DST]\n", substr($0,8,4), monthint, substr($0,1,2), substr($0, 13,2), substr($0, 16,2), substr($0, 19,2) );
# calculate difference
difference = systime() - mktime(mktimeformat);
# printf("%s - %s = %s\n",systime(), mktime(mktimeformat), difference);
printf("%s\n",REQUESTS/difference);
} ' `
echo "APACHE_RPS|${APACHE_RPS}"

我编写了一组Perl脚本,显示过去1分钟,5分钟和15分钟的平均请求数(如上)。它位于https://gist.github.com/1040144。

mod_status是一个!如果你打电话给:
的http:// {IP} /服务器状态刷新= 1&安培;自动刷新=真
然后它每2秒自动刷新一次,这样你就可以看到一个恒定的实时视图: - )
