http-check string and rerturn code != 200 behaviour
Hi, I'm using an http-check expect string to test the presence of a certain string in the body response. Like this option httpchk GET /mycheck HTTP/1.1\r\nHost:\ myhost.xx\r\nConnection:\ close http-check expect ! string healthStatus:Unhealthy When the backend is not accessible, our nginx returns a default page, with a 5XX return code. In this case (return code != 200), it should be considered as an error, and the associated serveur should be removed from the server. It's not the case : HAProxy only check the string, and says it's OK. Question : How to check the string AND check the return code ? I want my server to be removed if string is absent OR if return code is != 200 ! Thank you, Sébastien Rohaut

Load Problem with v1.5.5+
Hello, Our installation and configuration of HAProxy v1.5.3 on Debian GNU/Linux Wheezy (v7.8, fully patched to date, and running on bare metal with no virtualization) has been stable. I have an active/passive server deployment using keepalived, and they have been running without issue on this version since 7/31/14. HAProxy interfaces with a backend Windows Server 2008 R2/IIS v7.5 web farm. The physical servers are Dell PowerEdge R310 with (1) Intel Xeon X3430 (4 cores) @2.4GHz and 32GB of RAM (@800 MHz). Each server has bond0 configured, which is comprised of eth0 and eth1, and each physical interface connects to a switch stack (Cisco Catalyst 3750) using 802.3ad. The on-board network cards are Broadcom Corporation NetXtreme II BCM5716 Gigabit Ethernet (rev 20). Cisco 3750 switch interface configuration and statistic reporting (i.e. input/output errors, CRCs, etc.) is clean. The backend servers are physically connected to the same Cisco 3750 switch stack. Active/passive high availability for HAProxy using keepalived works as expected. HAProxy Statistics under normal weekly workloads reflect the following: Queue/Cur - 0, Max - some #, Limit -- Session rate/Cur - 1 to 200 per server Session rate/Max - 300 to 500 Session rate/Limit - blank Sessions/Cur - 1 to 30 per server; could spike to 50 Sessions/Max - 50 Sessions/Limit - 50 Denied Req/Resp - 0 Errors/Req - Errors/Conn - 0 Errors/Resp - usually 1+, but not incrementing fast (i.e., in six hours' time today there are 41 total) Warnings/Ret/Redis - 0 In January 2015, I tried to catch up on HAProxy maintenance releases by upgrading only our active server from v1.5.3 to v1.5.10 (before 1.5.11 was announced) late on a Tuesday night. Immediately post upgrade, the active server seemingly behaved per testing. Unfortunately, v1.5.10 surfaced a new problem early the next morning around 9:00 a.m. which forced me to fail over to our passive server (still running v1.5.3) in order to restore service to our customers, which was followed by downgrading our active server to v1.5.3 in order to stabilize the system and restore the high availability pair. *The problem exhibited the following behaviors on the active server: * * HAProxy Statistics (HPS) showed many, but not all, web farm servers with Queue/Cur in the low thousands, and they would remain there with minor queue count fluctuations both incrementing and decrementing by 100 every stats page refresh. For these same servers, the Sessions/Cur was stuck at 50, which is the configured Max Limit, which explains the queuing and why some customers weren't able to use our service. * HPS would intermittently flash yellow horizontal lines, also noting a very high 2000ms L7 response time, typically on the servers with the high queue count. * Stopping and starting the HAProxy service would shuffle around the numbers in HPS as to which server had the high queues, but not all servers would have high queues (only two or three would have them). Waiting for five or ten minutes wouldn't self heal the queues through session processing. * HPS would rarely flash a red horizontal line, and that server's sessions would seem to zero out its Queue/Cur. * CPU utilization (30%) and memory consumption ( 5GB) on the active node during the event are within standard trends. None of the backend web farm servers, per active cacti graphing, displayed any CPU, memory, or disk anomalies during this time. At the time, I decided to table any further upgrade attempts until I could research the issue further. On the night of 2/13/15, I thought I would try again with v1.5.11 even though I struggled to find anything relevant to my former experience in the /HAProxy ChangeLog/ or problems with my configuration. All weekend and early this morning, v1.5.11 behaved up until more customers came online and started using our services. Looking at our cacti graph, from 8:50 a.m. EST to 9:00 a.m. EST, our total ingress and egress traffic combined jumped from 80Mbps to 170Mbps. It was during this time that the problem described above surfaced again, causing a service failure for large amount of our customers. * @ 9:05 a.m. stopping and starting HAProxy v1.5.11 didn't resolve the problem. Waited six minutes for processing which didn't catch up. * @ 9:12 a.m. I downgraded HAProxy from v1.5.11 to v1.5.3 and everything normalized in less than a minute. * @ 9:16 a.m. I upgraded HAProxy from v1.5.3 to v1.5.5 and the problem surfaced again and didn't heal in five minutes' time. * @ 9:22 a.m. I downgraded HAProxy from v1.5.5 to v1.5.4 and everything normalized in less than a minute. It has been stable all day so far. Each time I would build HAProxy I would * wget http://haproxy.1wt.eu/download/1.5/src/haproxy-1.x.x.tar.gz * tar -xf haproxy-1.x.x.tar.gz * cd haproxy-1.x.x * service haproxy stop * make TARGET=linux2628 CPU=generic USE_PCRE=1 USE_OPENSSL=1

Is it possible for your to replay or generate traffic on test system ans use git bisect on 1.5.5 release? I think this is due to a bug prior to 1.5.5 : http://www.haproxy.org/git?p=haproxy-1.5.git;a=commit;h=2e47a3ab11188239abadb6bba7bd901d764aa4fb Your configuration matches the condition, meaning that with haproxy 1.5.4 and before, option http-server-close is ignore from your backends, and not ignored anymore in 1.5.5+. The direct effect is that the server connection is closed after each connection, and that every requests require a new SSL handshake (which can be a performance killer). We can verify this quickly : - using haproxy 1.5.5 and later, remove option http-server-close. It will default to option http-keep-alive, and see if it's better. - using haproxy 1.5.4 and before, move option http-server-close to the defaults section, I think it should reproduce the same issues. -- Cyril Bonté

Me, I try to choose a solution with two master, which will be my two HAProxy. Maybe it's impossible and i dream ^^, but this is what I need. well.. it all starts with a MAC address needing to be resolved from an IP. So if all your requests goes to one IP.. there will be one MAC responding to that ip - and hence one machine. Switches etc. cache which MAC belongs to which port etc. - so trying to fake MAC's and let 2 servers respond to the same MAC will give you issues :) You could probably do something like setting up a mirror port (or a hub) in between two servers - and then each will get all traffic.. and then they must agree for EACH request- who shall respond to it, and also notice if a response (the other one should have handled) is not handled.. and react.. it's simpler (and hence more performant) to let one machine respond to the ip (controlled by keepalived) - and then just ensure that someone responds to that ip (VRRP does this). - and then let the active part - delay traffic to both. But that will send all traffic past the active box first.. normally it's the responses that's large and hence that's normally ok. LVS can do Direct Routing, where it leaves the destination IP alone, so it simply forwards the package to another MAC address - and you can then setup your other haproxy box, to also react to that ip. (I normally setup the ip on loopback interface - but take care that it does not disturb keepalived :) so in reality someone has to be master.. and in normal active/active cluster setups - there is indeed a master - and the cluster then reelects a new master, whenever the master is inresponsive. -- Regards, Klavs Klavsen, GSEC - k...@vsen.dk - http://www.vsen.dk - Tlf. 61281200 Those who do not understand Unix are condemned to reinvent it, poorly. --Henry Spencer
