Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

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

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

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.


There are 6 alternatives - vote for the best!

Terminal - Alternatives
watch "netstat -plan | grep -v LISTEN | grep \":80 \" | awk {'print \$5'} | cut -d: -f 1 | uniq -c | sort -nk 1"

Doesn't list connections to other ports than port 80. Not f.e. 8080 or 8091.

Excludes programs listening for connections, like your favorite webserver.

Know a better way?

If you can do better, submit your command 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)

The suggested commands will also list connections to, which is one of the default ports of couchbase (http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-getting-started-install-ubuntu.html).
