get content from different origin server

Hi ,

We have have a scenario, where we have to point three origin server in parent config, when client requested to play a video any one of the origin server which having video need to complete the request.
Please any one suggest me .

Parent config with two origin server

dest_domain=10.55.0.109 port=80  parent="10.55.0.109:80; 10.55.0.108:80" parent_is_proxy=false parent_retry=simple_retry

parent config with three origin server:

dest_domain=10.55.0.109 port=80  parent="10.55.0.109:80; 10.55.0.108:80; 10.111.10.8:80" parent_is_proxy=false parent_retry=simple_retry

works fine with two origins ,but it  did not work with three origins .

FWIW, these are also reloadable. So, you can set them on the command line:
traffic_ctl config set proxy.config.diags.debug.tags
"http.*|dns.*|parent_select"
traffic_ctl config set proxy.config.diags.debug.enabled 1

(don't forget to unset the debug logs. If you are getting any sort of
volume, your log will be quickly full!)

Vasath,

Edit your records.config and modify the following config parameters:

CONFIG proxy.config.diags.debug.enabled INT 1
CONFIG proxy.config.diags.debug.tags STRING http.*|dns.*|parent_select

or use

CONFIG proxy.config.diags.debug.tags STRING parent_select

then execute 'traffic_ctl config reload'

you should then see debug logging.

To disable debug looging:
CONFIG proxy.config.diags.debug.enabled INT 0
traffic_ctl config reload

Vasanth,

Instead of dest_domain, use dest_ip in your example.  dest_domain would match on the remapped fqdn or you could use a wild card of dot, '.'.

Since you did not specify a round_robin type, it defaults to 'false' which means the first parent is always chosen until it fails and is marked down.
If the content isn't on the first parent, it will retry using the second parent becuase you have enabled simple_retry.  The maximum number of retries for simple_retry defaults to 1 so,

Vasanth,

Instead of dest_domain, use dest_ip in your example.  dest_domain would match on the remapped fqdn or you could use a wild card of dot, '.'.

Since you did not specify a round_robin type, it defaults to 'false' which means the first parent is always chosen until it fails and is marked down.
If the content isn't on the first parent, it will retry using the second parent becuase you have enabled simple_retry.  The maximum number of retries for simple_retry defaults to 1 so,
it will not try the third parent unless you set max_simple_retries to 2, ie in the parent.config line, add 'max_simple_retries=2'

Re: get content from different origin server

Posted by John Rushford <jj...@gmail.com>.
I'm assuming the second parent was chosen in your test because of
simple_retry.  If the first parent is marked down, then the second parent
would be chosen and a single simple_retry would have worked to the third
parent.

Re: get content from different origin server

Posted by John Rushford <jj...@gmail.com>.
Vasanth,

Instead of dest_domain, use dest_ip in your example.  dest_domain would
match on the remapped fqdn or you could use a wild card of dot, '.'.

Since you did not specify a round_robin type, it defaults to 'false' which
means the first parent is always chosen until it fails and is marked down.
If the content isn't on the first parent, it will retry using the second
parent becuase you have enabled simple_retry.  The maximum number of
retries for simple_retry defaults to 1 so,
it will not try the third parent unless you set max_simple_retries to 2, ie
in the parent.config line, add 'max_simple_retries=2'

Try changing max_simple_retries.  If you still have trouble, turn on
debugging using 'parent_select', then we can look at the  logs.

thanks
John
