Monitor open connections for httpd including listen, count and sort it per IP

watch "netstat -plan|grep :80|awk {'print \$5'} | cut -d: -f 1 | sort | uniq -c | sort -nk 1"
It's not my code, but I found it useful to know how many open connections per request I have on a machine to debug connections without opening another http connection for it. You can also decide to sort things out differently then the way it appears in here.

What Others Think

netstat -pltn|awk '/:80/ {++B[$5]} END {for(a in B) print a, B[a]}' (add the awk code to sort by value or use the pipe to sort -nk1)
