Re: Detecting Flapping Service

Hi Jonathan,

The "rise" directive did the trick for me. Thanks for your help.

Detecting Flapping Service

[Amit More]

Hi,

I have a Ubuntu Server 10.04 (64-bit) running HAProxy 1.4.21 in TCP mode and I 
was wondering if HAProxy is capable of detecting and removing a flapping 
service from the pool. If not, is there any workaround that'll take care of 
flapping services? Any help would be appreciated. 

Thanks,
Amit

Client Stickiness with Roundrobin Algorithm

[Amit More]

Hello All,

I have set up HAProxy (version 1.3.22 on Ubuntu Server 10.04 64-bit) with 
"source" as the load balancing algorithm and it works fine. I was wondering if  
i could configure HAProxy to use "roundrobin" with client timeout. What i mean 
is that the client should be timed out after some inactivity time and the 
client's request after the timeout should be served by the next available 
server. I have tried "roundrobin" with "timeout client 5m" but the client was 
timed out before the 5m timer expired. 
If i have understood the "timeout client" directive of the haproxy.cfg file 
correctly, then why is the client request routed to a different server before 
the timer (timeout client) expires? If I've got that totally wrong, can 
somebody please explain to me how to achieve stickiness with roundrobin (or 
leastconn) algorithm?
Appreciate your time and help.

Thanks,
Amit
