In Windows for ASP, you can get it perfmon, but... How to get "requests per second" for Apache in Linux? In realtime, or can you use mod_status ? And apparently, there is a version of top for apache ... Adam Franco Here is a short bash script I made up to sample the request rate (based on dicroce's suggestion of using wc -l on the log file). #!/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

I'm debugging communications with a serial device, and I need to see all the data flowing both directions. It seems like this should be easy on Linux, where the serial port is represented by a file. Is there some way that I can do a sort of "bi-directional tee", where I tell my program to connect to a pipe that copies the data to a file and also shuffles it to/from the actual serial port device? I think I might even know how to write such a beast, but it seems non-trivial, especially to get all of the ioctls passed through for port configuration, etc. Has anyone already built such a thing? It

Does anyone know of a tool to visually show the memory usage of a selected process on Ubuntu? ps aux will show a numerical snapshot, but I'd really like a line I can watch change as I hammer the process and hopefully see unexpected behaviours. Has anyone got any suggestions? LovesTha I couldn't find any real tools to do it. But I have found a neat small set of scripts that'll do it. Using this little bash loop to do the logging: while true; do ps -C <ProgramName> -o pid=,%mem=,vsz= >> /tmp/mem.log gnuplot /tmp/show_mem.plt sleep 1 done & This will create a nice little log file of memory usage

I would like to monitor user behaviors inside a winforms application. Is there a general way to hook into the eventing system, without having to write event handlers in every form, or on every button? I Would like to monitor following events accross the application: Windows opened Windows closed Buttons clicked Ideally: time spend in each form I dont want to subscribe to all the events in all the forms, the application is to big for that. I would just like to hook in and monitor all events. You don't need to write event handles in every form and for every control. You can put the logic in a
