Hello,

I have a problem with my command:

/usr/lib/centreon/plugins/centreon_haproxy_web.pl --plugin=apps::haproxy::web::plugin --mode=backend-usage --hostname=xxxxxx --port=8404 --proto=http --username='centreon' --password='xxxxxxx' --filter-name='.*' --verbose --urlpath=/haproxy?stats --credentials

I have this return:
UNKNOWN: Cannot decode response (add --debug option to display returned content)

When I do a --debug, I have the information that comes back, it connects well to the API but with a bad format, for example:

 

My HAproxy: HAProxy version 2.9.14-1ppa1~jammy

I relied on the recommendations: https://docs.centreon.com/fr/pp/integrations/plugin-packs/procedures/applications-haproxy-web/

thanks you :)

 

Hello :)

Could you show us more about the debug output? An user meet maybe a similar issue and reported it in github here if it may help you to find where the issue occurs.

Kind regards.

Hi, see my --debug info. The rest is long, there are all my backends after. do you have any idea?
Thanks

Your demo link works fine from my centreon, but not mine
