Hi! I use HA-Proxy version 1.5.6 2014/10/18/ . Red hat 6. I want use alert via mail. I find informations about this: ----------------------------------- Patch HAProxy So this brings us on to option 3 patch HAProxy to send the alerts, after all how hard can it be? As I don’t really want to write my own SMTP client or use any other library’s lets go with the easy option of using mailx from the mailutils package as we know it works. The following was written for HAProxy dev18. Now I’m no developer so take the code more of a proof of concept instead of something to add to your production environment.
Most of the work is already done for us, as HAProxy has functions for setting a server up or down and also has an array containing the server name, server’s status etc. So all we need to do is add our own function to send the email and parse the email address from the configuration file. This done in the following patch files: cfgparse.c checks.c log.c global.h So in the configuration file I have added the option “email_alert” to the global section with to and from address. http://blog.loadbalancer.org/3-ways-to-send-haproxy-health-check-email-alerts/ ------------------------------------- I try add text from patch file in the end original file and make haproxy file. /opt/haproxy/global.h.diff >> /opt/haproxy/include/types/global.h cat /opt/haproxy/cfgparse.diff >>/opt/haproxy/haproxy-1.5.6/src/cfgparse.c cat /opt/haproxy/log.diff >>/opt/haproxy/haproxy-1.5.6/src/log.c cat /opt/haproxy/checks.diff >>/opt/haproxy/haproxy-1.5.6/src/checks.c And while compiling I have error: [webadmin@srv-lb-qa haproxy-1.5.6_with_diff]$ make TARGET=linux2628 CPU=generic gcc -Iinclude -Iebtree -Wall -O2 -g -fno-strict-aliasing -DCONFIG_HAP_LINUX_SPLICE -DTPROXY -DCONFIG_HAP_LINUX_TPROXY -DCONFIG_HAP_CRYPT -DENABLE_POLL -DENABLE_EPOLL -DUSE_CPU_AFFINITY -DASSUME_SPLICE_WORKS -DUSE_ACCEPT4 -DNETFILTER -DUSE_GETSOCKNAME -DCONFIG_HAPROXY_VERSION=\"1.5.6\" -DCONFIG_HAPROXY_DATE=\"2014/10/18\" \ -DBUILD_TARGET='"linux2628"' \ -DBUILD_ARCH='""' \ -DBUILD_CPU='"generic"' \ -DBUILD_CC='"gcc"' \ -DBUILD_CFLAGS='"-O2 -g -fno-strict-aliasing"' \ -DBUILD_OPTIONS='""' \ -c -o src/haproxy.o src/haproxy.c In file included from include/proto/proxy.h:28, from include/common/cfgparse.h:30, from src/haproxy.c:61: include/types/global.h:207: error: expected identifier or ‘(’ before ‘--’ token include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:213: error: expected identifier or ‘(’ before ‘+’ token include/types/global.h:215: error: expected identifier or ‘(’ before ‘+’ token include/types/global.h:216: error: expected identifier or ‘(’ before ‘+’ token In file included from src/haproxy.c:76: include/types/global.h:207: error: expected identifier or ‘(’ before ‘--’ token include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:213: error: expected identifier or ‘(’ before ‘+’ token include/types/global.h:215: error: expected identifier or ‘(’ before ‘+’ token include/types/global.h:216: error: expected identifier or ‘(’ before ‘+’ token In file included from include/proto/channel.h:35, from src/haproxy.c:85: include/types/global.h:207: error: expected identifier or ‘(’ before ‘--’ token include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:209: error: stray ‘@’ in program include/types/global.h:213: error: expected identifier or ‘(’ before ‘+’ token include/types/global.h:215: error: expected identifier or ‘(’ before ‘+’ token include/types/global.h:216: error: expected identifier or ‘(’ before ‘+’ token make: *** [src/haproxy.o] Error 1 Pls help me!
