Hi folks. For our company's convenience, we prefer to have our HAProxy unit script also allow us to talk to the stats socket. We also do a couple other things, like show connections with a "status" argument. Perhaps you can use it too.
Code and readme here: https://github.com/flores/haproxyctl A copy of that readme with examples is below. Note you need to enclose something like "show sess" (spaces) in quotes. Suggestions or requests for features is appreciated! ----- Simple wrapper to make life with HAProxy a little more convenient. It talks to or creates the stats socket and pid file, and doubles as an init script for those folks who installed haproxy from source. Here's a blog post about the inspiration for it: http://borderstylo.com/posts/228-haproxy-the-quick-and-the-dirty Examples of usage: # ./haproxyctl usage: ./haproxyctl <argument> where argument can be: start : start haproxy unless it is already running stop : stop an existing haproxy restart : restart the process status : is haproxy running? on what ports per lsof? configcheck : check /etc/haproxy/haproxy.cfg cloudkick : cloudkick.com-friendly status and metric for connected users clear counters : clear max statistics counters (add 'all' for all counters) help : this message prompt : toggle interactive mode with prompt quit : disconnect show info : report information about the running process show stat : report counters for each proxy and server show errors : report last request and response errors for each proxy show sess [id] : report the list of current sessions or dump this session get weight : report a server's current weight set weight : change a server's weight set timeout : change a timeout setting disable server : set a server in maintenance mode enable server : re-enable a server that was previously in maintenance mode # ./haproxyctl status haproxy is running. these ports are used and guys are connected. *:www (LISTEN) *:49122 # ./haproxyctl "show stat" # pxname,svname,qcur,qmax,scur,smax,slim,stot,bin,bout,dreq,dresp,ereq,econ,eresp,wretr,wredis,status,weight,act,bck,chkfail,chkdown,lastchg,downtime,qlimit,pid,iid,sid,throttle,lbtot,tracked,type,rate,rate_lim,rate_max,check_status,check_code,check_duration,hrsp_1xx,hrsp_2xx,hrsp_3xx,hrsp_4xx,hrsp_5xx,hrsp_other,hanafail,req_rate,req_rate_max,req_tot,cli_abrt,srv_abrt, http,FRONTEND,,,3,3,2000,4,1641,4353,0,0,0,,,,,OPEN,,,,,,,,,1,1,0,,,,0,0,0,2,,,,0,2,2,0,0,0,,0,2,4,,, ei,guinea,0,0,0,0,,0,0,0,,0,,0,0,0,0,UP,1,1,0,0,0,28,0,,1,2,1,,0,,2,0,,0,L4OK,,0,0,0,0,0,0,0,0,,,,0,0, ei,belem,0,0,0,0,,0,0,0,,0,,0,0,0,0,UP,1,0,1,0,0,28,0,,1,2,2,,0,,2,0,,0,L4OK,,42,0,0,0,0,0,0,0,,,,0,0, ei,BACKEND,0,0,0,0,0,0,0,0,0,0,,0,0,0,0,UP,1,1,1,,0,28,0,,1,2,0,,0,,1,0,,0,,,,0,0,0,0,0,0,,,,,0,0, apache,guinea,0,0,0,0,,0,0,0,,0,,0,0,0,0,UP,1,1,0,0,0,28,0,,1,3,1,,0,,2,0,,0,L4OK,,0,0,0,0,0,0,0,0,,,,0,0, apache,belem,0,0,0,0,,0,0,0,,0,,0,0,0,0,UP,1,0,1,0,0,28,0,,1,3,2,,0,,2,0,,0,L4OK,,42,0,0,0,0,0,0,0,,,,0,0, apache,BACKEND,0,0,0,0,0,0,0,0,0,0,,0,0,0,0,UP,1,1,1,,0,28,0,,1,3,0,,0,,1,0,,0,,,,0,0,0,0,0,0,,,,,0,0, sinatra,sinatra_downoi,0,0,0,1,,1,484,3641,,0,,0,0,0,0,UP,1,1,0,0,0,28,0,,1,4,1,,1,,2,0,,1,L4OK,,46,0,1,0,0,0,0,0,,,,0,0, sinatra,sinatra_rindica,0,0,0,0,,0,0,0,,0,,0,0,0,0,UP,1,1,0,0,0,28,0,,1,4,2,,0,,2,0,,0,L4OK,,45,0,0,0,0,0,0,0,,,,0,0, sinatra,sinatra_guinea,0,0,0,0,,0,0,0,,0,,0,0,0,0,DOWN,1,1,0,0,1,2,2,,1,4,3,,0,,2,0,,0,L4CON,,0,0,0,0,0,0,0,0,,,,0,0, sinatra,BACKEND,0,0,0,1,0,1,484,3641,0,0,,0,0,0,0,UP,2,2,0,,0,28,0,,1,4,0,,1,,1,0,,1,,,,0,1,0,0,0,0,,,,,0,0, static,ngnix_downoi,0,0,0,1,,1,153,264,,0,,0,0,0,0,UP 1/2,1,1,0,0,0,28,0,,1,5,1,,1,,2,0,,1,INI,,,0,1,0,0,0,0,0,,,,0,0, static,ngnix_petite,0,0,0,1,,1,522,230,,0,,0,0,0,0,UP 1/2,1,1,0,0,0,28,0,,1,5,2,,1,,2,0,,1,INI,,,0,0,1,0,0,0,0,,,,0,0, static,ngnix_rindica,0,0,0,1,,3,0,0,,0,,0,0,2,1,UP 1/2,1,1,0,0,0,28,0,,1,5,3,,1,,2,0,,1,INI,,,0,0,0,0,0,0,0,,,,0,0, static,nginx_stellatus,0,0,0,1,,1,482,218,,0,,0,0,0,0,UP 1/2,1,1,0,0,0,28,0,,1,5,4,,1,,2,0,,1,INI,,,0,0,1,0,0,0,0,,,,0,0, static,nginx_belem,0,0,0,0,,0,0,0,,0,,0,0,0,0,UP 1/2,1,1,0,0,0,28,0,,1,5,5,,0,,2,0,,0,INI,,,0,0,0,0,0,0,0,,,,0,0, static,nginx_petite,0,0,0,0,,0,0,0,,0,,0,0,0,0,UP 1/2,1,1,0,0,0,28,0,,1,5,6,,0,,2,0,,0,INI,,,0,0,0,0,0,0,0,,,,0,0, static,apache_guinea,0,0,0,0,,0,0,0,,0,,0,0,0,0,UP 1/2,1,1,0,0,0,28,0,,1,5,7,,0,,2,0,,0,INI,,,0,0,0,0,0,0,0,,,,0,0, static,BACKEND,0,0,0,1,0,3,1157,712,0,0,,0,0,2,1,UP,7,7,0,,0,28,0,,1,5,0,,4,,1,0,,2,,,,0,1,2,0,0,0,,,,,0,0, The real magic in the script (talking to the stats socket) is under the else case in the ARGV argument, or here: https://gist.github.com/632613 Thank you for HAProxy and a great list!
