load balancer byrequest algorithm

["Chen, Yongcheng" <Yongcheng.Chen@xxxxxxxxxxxx>]

Hi everybody,

 

I’m testing now the apache load balancer. And I configured my apache server for testing the example from apache document (http://httpd.apache.org/docs/2.2/mod/mod_proxy_balancer.html):

 

worker	a	b
lbfactor	70	30
lbstatus	-30	30
lbstatus	40	-40
lbstatus	10	-10
lbstatus	-20	20
lbstatus	-50	50
lbstatus	20	-20
lbstatus	-10	10
lbstatus	-40	40
lbstatus	30	-30
lbstatus	0	0
(repeat)   My configuration was:

    <Proxy balancer://ServerCluster>

      BalancerMember http://vh-srv01:8080 min=1 max=50 loadfactor=70 route=vh-srv01

      BalancerMember http://vh-srv02:8080 min=1 max=50 loadfactor=30 route=vh-srv02

</Proxy>

 

And I used also the setting: “lbmethod=byrequests”

 

I expected such a schedule: “a b a a a b a a b a”

However in the real test, I got “a a b a a b a a a b”.

 

Can somebody explain what is the problem?

 

Best Regards
