How to get \"requests per second\" for Apache in Linux?

Answer 1

To sum up, you can use mod_status and apachetop.

Alternatively, you can use Adam Franco's and Jon Daniel's nice scripts to have a live look.

If you would like to have a look at a partiular date and hour, you can issue this little command:

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}'

Replace with the date and hour you are interested and also with the proper pathfilename of the log file.

It will print out something like:

1913 12:47
 226 12:48
 554 12:49
 918 12:50

There is a nice article here with more options on using a combination of awk, cut and uniq commands to get quick stats of the kind.
