Save test messages into Prometheus

[Pasha Nesm]

Can I push a text message (JSON format) to Prometheus (or Prometheus poll this message)?

I have the endpoint:

@RestController
@RequestMapping("/message")
public class MessageController {

    @PostMapping()
    @ResponseStatus(CREATED)
    public void postMessage(@RequestBody String message) {
     //TODO save message into Prometheus
    }   
}

I think you're referring to prometheus.io.

It appears to be a service for monitoring metrics about your web application. There are Java libraries available that help you instrument your code: https://github.com/prometheus/client_java

I don't know what you mean by "push a text message to Prometheus". It's not a general purpose database. Please explain what you're trying to achieve.

I mean, to push a string like an object to Prometheus.

That doesn't mean anything to me. What do you want Prometheus to do with it? For what purpose?
