2 years ago Hi,
curl -ik https://netscaler/nitro/v1/config/login -X POST -H 'Content-Type: application/json' -d '{ "login" :{"username": "username", "password": "password"}}' HTTP/1.1 201 Created
It does look like the system you are connecting to returns a 201, which will eventually require the fix in #11472. However, Telegraf is not getting that far and instead getting a 400 per your telegraf log. The Citrix ADC docs say the reason is in the body, so let's try to find out why.
I have put up #11482, which should have some artifacts attached shortly. Can you give that a try and see what the body says?

System info
Telegraf 1.22.4 (also tried 1.24.0~e945364b), Redhat 8.6
Docker
No response
Steps to reproduce
Expected behavior
I expect Telegraf HTTP plugin will connect to Citrix ADC and initiate the session, so I can draw stats using API calls
Moreover Telegraf stops on that error code 400, which in my humble opinion may be a bad design choice since it may crash otherwise a perfectly fine running Telegraf instance. Telegraf should just ignore the error and maybe retry later instead of stopping entirely. Imagine a situation where we have 1 HTTP endpoint and 99 SNMP devices. When we poll a device with HTTP plugin and it replies with non-200 code (because of some internal error), then whole Telegraf instance crashes and stops gathering statistics for those 99 perfectly working devices.
Actual behavior
E! [telegraf] Error running agent: could not initialize input inputs.http: cookie auth renewal received status code: 400 (Bad Request)
Additional info
When I use curl then it all works:

At first I thought that maybe Telegraf just won't accept code 201 as per https://github.com/influxdata/telegraf/issues/11134 so I tested new build https://github.com/influxdata/telegraf/pull/11472 but it still fails
