Response Content not in json format or plain text #32

Open juanprojas opened 2 months ago

juanprojas commented 2 months ago

Hi, i'm receiving as response in the content an array of numbers instead of a json with metrics, also i don't see header with plain text as others targets from prometheus. By the way, in the RawContent response i see the json with metrics but not in the Content header.

Do you know what can i do? or any info that help me to get a response in plain text format? thanks

@juanprojas what HTTP client are you using? I see plain text if I use curl:

$ curl -v http://$HOSTNAME:8161/metrics/

Hi i'm using curl from windows powershell, this brings 2 headers, Content and RawContent, the Content header shows {35, 32, 72, 69...}, the RawContent is ok. Can you test it from a windows powershell?

I have no way to run curl from a windows powershell but this issue doesn't seem related to artemis-prometheus-metrics-plugin it seems more related to the client you are using.
