If you log to local deamon, you should not lose anything in UDP.
Yes, I am logging to a local daemon.
However, if the syslog daemon starts after haproxy or can't keep up with
log rate, it can lose logs but then the unix socket

Hi,
In our system, front end send request to back end with tcp protocol. So we
configure HAProxy working in tcp mode.
Can we configure or develop in HAProxy and let HAProxy check contents in
request and dispatch request to specific server based on arbitrary rule ?
Regards
Hi,
We compiled the HAProxy on Solaris and did the basic configuration in
haproxy.cfg file where it receives the request from our Front End
application and distribute to different back-end servers.
We configured the HAProxy as TCP mode.
Now as per our requirement, we need to read the incoming
Hi,
Thxs a lot. Could you kindly let us know how can we read and understand
the incoming request.
I read we need to carry out the below changes to capture the HAProxy
log.
edit the value of SYSLOGD in /etc/default/syslogd
SYSLOGD=-r
Then set up syslog facility local0 and direct it to file

Just do as you would with other rules, however if you want to match some

As part of the request, the Front end sends the user name and some sort

We are not trying to use sql proxy, indeed we are using the TCP proxy.
Just we need to read the incoming request and based on the sql file name
we need to route the request to a backend server. We doesn't need to

You are going need something like mysql proxy for that.
haproxy can only look at the attributes of a connection (port, is there data
available from the client (aka did the client speak first), etc.
And in the case of httpd the headers but it can't look at the full contents of
the whole data

Sorry, if I am misguiding you.
I am just curious to know, when HAProxy is set at TCP mode, we want to
scan or glance over the incoming request for a particular string say
'XYZ'. If the incoming request contains the 'XYZ' string, route the
request to a backend xyz group else route
Hi Roy
You simply need to send an HTTP 1.1 request with a Host: header in the http
check, like this:
option httpchk GET /index.html\r\nHost: vhost.example.com

If you want haproxy to load balance across your databases and do so by
some value in the traffic, you'll need to expose your database via a
protocol that haproxy supports.
Write an RPC service that speaks HTTP and have haproxy load balance
across your RPC servers using HTTP values. This is
How about passing healthcheck.cluster6.corp.amiestreet.com for the option
httpchk, and also have the Apache VirtualHosts recognize healthcheck as a
ServerAlias? The idea here is your healthcheck will be standardized to each
host in the cluster, which you'll also want when you split these hosts,
Thxs a lot for the solution.
Unfortunately our client(Front End)is a legacy system and it was developed
around 20 years back and the current design of the client can't send A B
actions to one backend server/HAProxy port and B D to another backend
server/proxy.
Unfortunately the client is not
