Does Timer functionality exist in Prometheus.Client?

[cscoon]

I'm migrating our applications from Prometheus-net to Prometheus.Client.

I've been able to migrate all of the functionality we were using EXCEPT for the ITimer functionality.

Here is a sample of our existing code (with Prometheus-net):

Prometheus.Metrics.CreateHistogram(name, description,
    new HistogramConfiguration { LabelNames = MetricCollectorHelper.GetLabelNames(labels), Buckets = MetricCollectorHelper.GetHistogramBuckets(bucketType, _metricsConfiguration) })
        .WithLabels(MetricCollectorHelper.GetLabelValues(labels))
        .NewTimer()

Does this functionality exist in Prometheus.Client or in an extension somewhere?

We have similar functionality: ObserveDuration and ObserveDurationAsync extension methods that could be used for Histogram and Summary.

For example:

await myHistogram.WithLabels("a", "b").ObserveDurationAsync(async () => {
    await Task.Delay(1000);
});

The benefit of this approach - it's a determined moment of the observation (unlike nonintuitive at least for me observation in timer dispose).

I hope this helps =)
