Grafana graph plot data only once instead of again and again metric java

Question

I have implementation on java and Grafana/prometheus

From our java service we are ingesting payload to grafana and it plots

I have defined a Metric using java

public class MyPayloadService {

    
    private final AtomicInteger lastPayloadValue = new AtomicInteger(0);

    public MyPayloadService(MeterRegistry registry) {
        Gauge.builder("my.payload.value", this.lastPayloadValue, AtomicInteger::get)
            .description("The value from the most recently processed payload")
            .register(registry);
    }

    public void processPayload(int newPayloadValue) {
        this.lastPayloadValue.set(newPayloadValue);
        System.out.println("New payload value set to: " + newPayloadValue);
    }
}

Current it working with the same point is plotting again and again over a period of time

I am looking for something like if I ingest data1 in 12:00 and data2 12:30 in graph it should plot only once. something like in graph against 12:00 should be one point and 12:30 second point

but now its plotted again and again.

anyone can give suggestion may be using registry can we delete old one and keep only once.

IIRC, the problem is that you're using a Gauge: it will report the last value set until it changes. It sounds like you want a Histogram instead. — Mark Rotteveel

This is expected behaviour for metrics in Prometheus. From the sounds of it, you don't really need metrics, but rather logs instead. — markalex

I think you dislike getting a whole line while you only have distinct data points.

This is likely a feature of Grafana called Line interpolation. See configurable options here: https://grafana.com/docs/grafana/latest/panels-visualizations/visualizations/time-series/#line-interpolation

If you do not like that, maybe you need to switch to another kind of visualization.

I mean plot in grafana chart as points only once as per the ingestion time. Not as lines
