Batched metric request results in 400 response

[DrDJIng]

This was working fine a couple of months ago, but now the scraping seems to fail.

Specifically it's the batched metric request in main.go line 44, it fails with the response:

{"http_code":400,"message":{"details":"Some content in message body is not correct.","code":"ces.0014"}}

I tried a fresh copy of the repo, and got the same response.

Any help with this would be appreciated.

Hello, sorry for the late reply. I will look into it now.

I just ran the program didn't encounter the error like you did. Can you provide me more information?

• Where is your project located? eu-de/eu-nl?
• Do you know how many elements/services/objects you are trying to monitor?
• Anything else you think is important.

Best regards

So I dug into it more deeply, and when I finally managed to get a copy of the actual request being sent, the part of the json in the body that represents the metrics we're requesting was empty.

I'm still not entirely sure what causes this, since we were collecting resources, but the appropriate part of the request was empty.

Also haven't managed to pin down exactly what causes this to happen, but if I do figure that out, I'll update here.

I was able to reproduce your error.

If we call the batch metric API with an empty input, then the API endpoints returns this errors message:

{"code":400,"element":"Bad Request","message":"The system received a request which cannot be recognized","details":{"details":"Some content in message body is not correct.","code":"ces.0014"}}

I debugged into the relevant part of the code and made a screenshot of the variables. Here you can see that the JSON body is in fact empty and that the error is a HTTP 400.

I will fix soon and inform you about it this issue about it.

Thank you very much!
