Does using http client for retrieving flags get recorded as metrics?

[ghiden]

I want to use a http client rather than the official unleash client (Unleash Client SDK for Node.js) because I want on-demand based feature flag retrieval rather than polling.
I understand the official client sends metrics to /metrics endpoint separately.
If I make http GET requests against the server's endpoint, would these requests be recorded as metrics in the server?
If so, what metrics are tracked?

I'm not sure what client you're talking about and also not clear what type of metrics you're referring to. Metrics as per feature evaluation metrics have nothing to do with http client requesting features from Unleash, in general my answer would be no, but I'm not entirely sure this is what you're asking. If you could provide more context maybe I can provide a more precise answer.

@gastonfournier thanks for your response. I've updated my question. Hopefully it's clearer now.

Still unsure what's your ask, sorry. Are you wondering about our metrics API? We have it documented here: https://docs.getunleash.io/reference/api/unleash/register-client-metrics you can also look at other APIs documentation.

I'm also not sure whether you're looking into "http client" or "SDK". Are you trying to change the default http client (make-fetch-happen) from the SDK?

Or maybe you're trying to build something similar to what we've built recently in Android SDK: https://github.com/Unleash/unleash-android/blob/34a0c789991bf68e45c582c4d8b01d2f4b55fcd3/unleashandroidsdk/src/main/java/io/getunleash/android/Unleash.kt#L32-L42

There usually has to be a reason for not using polling, it's been a very effective and reliable solution so far.
