Webhooks are cool, but not how Prometheus works.

Wait, it doesn't use a database for metrics? That's surprising!

Prometheus uses HTTP to get metrics in JSON format.

I’m a bit confused; I thought Prometheus used SNMP too, but I guess that might be for other monitoring tools.

I practiced a question similar to this, and I think it was about how Prometheus collects data from applications. I feel like it might be option C.

I remember something about it querying a database, but that doesn't sound right for Prometheus. It feels like it uses a different method.

I think Prometheus gathers metrics using HTTP, but I'm not completely sure if it's JSON encoded or something else.

I'm pretty confident that Prometheus uses a webhook approach where the monitored applications submit various metrics, so I'll select option B.

I'm not entirely sure about the details of how Prometheus gathers information, but I think the HTTP JSON option sounds the most plausible, so I'll go with C.

Ah, I remember learning about this in class. Prometheus implements the ICMP and SNMP protocols to ping and query remote services, so I'll choose option A.

Hmm, I'm a bit confused on this one. I'll need to think it through carefully before selecting an answer.

I'm pretty sure Prometheus uses HTTP to retrieve JSON encoded metrics from the monitored objects, so I'll go with option C.

Haha, I can just imagine Prometheus trying to 'ping and query' services using ICMP and SNMP. That's definitely not how it works. C is the winner!

Option E sounds interesting, but I don't think running scripts on the Prometheus server is the way it gathers information. C is definitely the right answer here.
MA
Margot

Definitely, sticking with HTTP for retrieving metrics seems like a safer option.
VA
Van

Yeah, running scripts on the server seems like it could be risky.

I agree, that makes sense. Option E does sound interesting though.

I agree, C makes sense. It's a common way for Prometheus to gather information about monitored hosts and services.

I agree with Anthony. Option C is the way Prometheus collects metrics from the monitored services.

Option C seems to be the correct answer. Prometheus uses HTTP to scrape metrics from the monitored applications in JSON format.
