Hi Friends, I am trying to bump session limits via the maxconn in the global section as below:
cat /etc/haproxy/redacted-haproxy.cfg global maxconn 10000 stats socket /var/run/redacted-haproxy-stats.sock user haproxy group haproxy mode 660 level operator expose-fd listeners frontend redacted-frontend mode tcp bind :2004 default_backend redacted-backend backend redacted-backend mode tcp balance leastconn hash-type consistent server redacted_0 redacted01.qa:8443 check agent-check agent-port 8080 weight 100 send-proxy server redacted-684994ccd-6rn9q 192.168.39.223:8443 check port 8443 weight 100 send-proxy server redacted-684994ccd-c88d9 192.168.46.66:8443 check port 8443 weight 100 send-proxy server redacted-canary-58ccdb7cf4-47f4m 192.168.53.47:8443 check port 8443 weight 100 send-proxy NOTE: I removed some portion of the config for conciseness sake. However this did not seem to have any impact on HAProxy after a reload as seen below: echo "show stat" | socat unix-connect:/var/run/redacted-haproxy-stats.sock stdio | cut -d"," -f7 slim 2000 200 I do not know where 2000 and 200 are coming from as I did not at any point configure that, the maxconn was previously 4096. A more detailed stats output is below: echo "show stat" | socat unix-connect:/var/run/redacted-haproxy-stats.sock stdio # 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,comp_in,comp_out,comp_byp,comp_rsp,lastsess,last_chk,last_agt,qtime,ctime,rtime,ttime,agent_status,agent_code,agent_duration,check_desc,agent_desc,check_rise,check_fall,check_health,agent_rise,agent_fall,agent_health,addr,cookie,mode,algo,conn_rate,conn_rate_max,conn_tot,intercepted,dcon,dses, redacted-frontend,FRONTEND,,,0,2,2000,3694,0,0,0,0,0,,,,,OPEN,,,,,,,,,1,2,0,,,,0,3,0,9,,,,,,,,,,,0,0,0,,,0,0,0,0,,,,,,,,,,,,,,,,,,,,,tcp,,3,9,3694,,0,0, redacted-backend,redacted_0,0,0,0,1,,2,0,0,,0,,0,0,0,0,UP,94,1,0,0,0,1582,0,,1,3,1,,2,,2,0,,1,L4OK,,0,,,,,,,,,,,0,0,,,,,683,,via agent : up,0,0,0,0,L7OK,0,50,Layer4 check passed,Layer7 check passed,2,3,4,1,1,1,10.185.57.54:8443,,tcp,,,,,,,, redacted-backend,redacted-684994ccd-6rn9q,0,0,0,1,,46,0,0,,0,,0,0,0,0,UP,100,1,0,0,0,1582,0,,1,3,2,,46,,2,0,,1,L4OK,,0,,,,,,,,,,,0,0,,,,,6,,,0,0,0,1,,,,Layer4 check passed,,2,3,4,,,,192.168.39.223:8443,,tcp,,,,,,,, redacted-backend,redacted-684994ccd-c88d9,0,0,0,1,,45,0,0,,0,,0,0,0,0,UP,100,1,0,0,0,1582,0,,1,3,3,,45,,2,0,,1,L4OK,,0,,,,,,,,,,,0,0,,,,,12,,,0,0,0,0,,,,Layer4 check passed,,2,3,4,,,,192.168.46.66:8443,,tcp,,,,,,,, redacted-backend,redacted-canary-58ccdb7cf4-47f4m,0,0,0,1,,45,0,0,,0,,0,0,0,0,UP,100,1,0,0,0,1582,0,,1,3,4,,45,,2,0,,1,L4OK,,0,,,,,,,,,,,0,0,,,,,10,,,0,0,0,1,,,,Layer4 check passed,,2,3,4,,,,192.168.53.47:8443,,tcp,,,,,,,, redacted-backend,BACKEND,0,0,0,2,200,3694,0,0,0,0,,0,0,0,0,UP,394,4,0,,0,1582,0,,1,3,0,,138,,1,3,,9,,,,,,,,,,,,,,0,0,0,0,0,0,6,,,0,0,0,1,,,,,,,,,,,,,,tcp,leastconn,,,,,,, I need guidance on what I need to do to configure session limits correctly and also make it reflect in the exported metrics. Thanks! Abejide Ayodele It always seems impossible until it's done. --Nelson Mandela
