GrafanaCloud Hosted Metrics

GrafanaCloud Hosted Metrics

The App.Metrics.Reporting.GrafanaCloudHostedMetrics nuget package reports metrics to GrafanaCloud Hosted Metrics using the App.Metrics.Formatters.GrafanaCloudHostedMetrics nuget package to format metrics.

Getting started

To use the GrafanaCloud Hosted Metrics reporter, first install the nuget package:

nuget install App.Metrics.Reporting.GrafanaCloudHostedMetrics

Then enable the reporter using Report.ToHostedMetrics(...):

var metrics = new MetricsBuilder()
    .Report.ToHostedMetrics("base url of your hosted metrics", "your hosted metrics api key")

App Metrics at the moment leaves report scheduling up the the user unless using App.Metrics.AspNetCore.Reporting. To run all configured reports use the ReportRunner on IMetricsRoot:

await metrics.ReportRunner.RunAllAsync();

Report Scheduling will be added when Microsoft.Extensions.Hosting.Background is released, otherwise there are various other scheduling solutions available for C#. For ASP.NET Core reporting see details on the App.Metrics.AspNetCore.Reporting support package.


Configuration options are provided as a setup action used with ToHostedMetrics(...).

To configure GrafanaCloud Hosted Metrics reporting options:

var filter = new MetricsFilter().WhereType(MetricType.Timer);
var metrics = new MetricsBuilder()
        options => {
            options.HostedMetrics.BaseUri = "base url of your hosted metrics";
            options.HostedMetrics.ApiKey = "your hosted metrics api key";
            options.HttpPolicy.BackoffPeriod = TimeSpan.FromSeconds(30);
            options.HttpPolicy.FailuresBeforeBackoff = 5;
            options.HttpPolicy.Timeout = TimeSpan.FromSeconds(10);
            options.Filter = filter;
            options.FlushInterval = TimeSpan.FromSeconds(20);

The configuration options provided are:

Option Description
MetricsHostedMetricsJsonOutputFormatter The metric payment formatter used when reporting metrics to GrafanCloud Hosted Metrics.
Filter The filter used to filter metrics just for this reporter.
FlushInterval The delay between reporting metrics to InfluxDB.
InfluxDb.BaseUri The URI of the GrafanaCloud Hosted Metrics instance.
InfluxDb.ApiKey The Api Key which your application will use to authenticate with GrafanaCloud Hosted Metrics.
HttpPolicy.BackoffPeriod The TimeSpan to back-off when metrics are failing to report to the metrics ingress endpoint.
HttpPolicy.FailuresBeforeBackoff The number of failures before backing-off when metrics are failing to report to the metrics ingress endpoint.
HttpPolicy.Timeout The HTTP timeout duration when attempting to report metrics to the metrics ingress endpoint.

Web Monitoring


The App.Metrics.AspNetCore.Tracking nuget package automatically records typical web metrics when added to an ASP.NET Core application. App Metrics includes a couple of pre-built Grafana dashboards to visualize these metrics:

Install the App Metrics Grafana dashboard. There is also an OAuth2 dashboard for APIs using OAuth2.
