Im testing directors in varnish 2.0 beta 2 with two backends.
The thing is that only one machine is getting all the traffic when using random
directors and .weight = 1 on both backends.
It seems like the last assigned backend in the director is the one that's
getting all the traffic.
If I use probing on the backends they both work.
[VCL]
backend child_1 {
.host = "192.168.0.192";
.port = "80";
/*
.probe = {
.url = "/Portals/0/logo1.gif";
.timeout = 1s;
.interval = 1s;
.window = 8;
.threshold = 6;
}
*/
}
backend child_2 {
.host = "192.168.0.193";
.port = "80";
/*
.probe = {
.url = "/Portals/0/logo1.gif";
.timeout = 100 ms;
.interval = 1s;
.window = 10;
.threshold = 8;
}
*/
}
director www_director random {
{
.backend = child_2;
.weight = 1;
}
{
.backend = child_1;
.weight = 1;
}
}
sub vcl_recv {
set req.backend = www_director;
# Cacha endast filer av denna filtyp
# *.jpg , *.jpeg , *.gif , *.png, *.js , *.css , *.swf
if (req.url ~ "\.(jpg|gif|png|js|css|swf)$") {
lookup;
}
pass;
} #RECV
sub vcl_fetch {
# Cacha endast filer av denna filtyp
# *.jpg , *.jpeg , *.gif , *.png, *.js , *.css , *.swf
if (req.url ~ "\.(jpg|gif|png|js|css|swf)$") {
set obj.ttl = 1h;
deliver;
}
pass;
} #FETCH
[/VCL]
In this case child_1 is getting all the traffic.
If I switch child_1 with child_2 in the director then child_2 is the one that
gets all the traffic.
