Hello guys!
Guanlan Dai has written a new tool for my Nginx Systemtap Toolkit,
named ngx-lua-conn-pools, to dump out the current details of all the
cosocket connection pools in any Nginx worker process that you specify
by pid:
https://github.com/agentzh/nginx-systemtap-toolkit#ngx-lua-conn-pools
You can use this tool to tune your connection pool settings according
to the actual online behavior.
We're going to add more features to this tool like connection lifetime
statistics.
Have fun!
