[apps::haproxy::web::plugin] - Cannot decode response (add --debug option to display returned content)

[FranckLANTZ]

Hello,
I'm trying to use this plugin, but it seems that it can't decode the response. In debug mode I can clearly see the html code with all the backends without any particular error message.

command sample
/usr/lib/centreon/plugins//centreon_haproxy_web.pl --plugin=apps::haproxy::web::plugin --mode=backend-usage --hostname='xxx' --port='xxx' --proto='http' --username='xxx' --password='xxx' --filter-name='.*' --verbose --credentials --basic --debug

response begin

Authorization: Basic ==
Content-Type:application/json
Accept:application/json

=> Recv header: HTTP/1.1 200 OK
=> Recv header: Cache-Control: no-cache
=> Recv header: Content-Type: text/html
=> Recv header: Transfer-Encoding: chunked
=> Recv header:
=> Recv data: 001c2f

Perhaps it's because response is chunked, but I can find any parameter to change it.

Any idea ?

Best regards,

Hello :)

I have the feeling that the response is not being retrieved because it is in Content-Type: text/html and Content-Type:application/json.
To compare, you can check the behaviour of the HAPRoxy demo with the following command:

 perl centreon_plugins.pl --plugin=apps::haproxy::web::plugin  --hostname='demo.haproxy.org' --port='80' --urlpath='/;json' --mode=backend-usage --debug

Thank you,

With the '/;json' parameter on the demo website, it works.

Will try to reconfigure stat part of my LB to add a application/json header.
