JF91.AppMetrics.InfluxDB2.Net7

Saya telah membuat paket ini sehingga Anda dapat dengan mudah mengintegrasikan App.Metrics ke dalam ASP WEB API Anda untuk mengirim metrik yang dikumpulkan ke Server InfluxDB2.

Penyiapannya sangat mudah, cukup instal Paket Nuget, tambahkan bagian konfigurasi ke appsettings.json Anda dan masukkan layanan ke program.cs Anda.

Harap ikuti instruksi dengan cermat.

Instal Nuget:

 dotnet add package JF91.AppMetricsInfluxDB2 --version 1.2.0

1 - Tambahkan bagian ini ke appsettings.json Anda dan ubah sesuai kebutuhan Anda:

 "MetricsOptions": {
    "DefaultContextLabel": "MyCustomContext",
    "Enabled": true
},
    "MetricsWebTrackingOptions": {
    "ApdexTrackingEnabled": true,
    "ApdexTSeconds": 0.1,
    "IgnoredHttpStatusCodes": [ 404 ],
    "IgnoredRoutesRegexPatterns": [],
    "OAuth2TrackingEnabled": true
},
    "MetricEndpointsOptions": {
    "MetricsEndpointEnabled": true,
    "MetricsTextEndpointEnabled": true,
    "PingEndpointEnabled": true,
    "EnvironmentInfoEndpointEnabled": true
},
    "MetricsReportingInfluxDb2Options": {
    "InfluxDb2": {
    "BaseUri": "http://127.0.0.1:8086",
    "Organization": "metrics",
    "Bucket": "metrics",
    "Token": "changeme"
},
    "HttpPolicy": {
    "BackoffPeriod": "0:0:30",
    "FailuresBeforeBackoff": 5,
    "Timeout": "0:0:40"
},
    "ReportInterval": "0:0:1"
}

2 - Tambahkan Variabel Lingkungan ini ke launchSettings.json Anda :

 "APPLICATION_NAME": "MyKickassApi"

3 - Tambahkan ini sebelum builder.Build() :

 builder.Services.AddMetricsServices();
builder.WebHost.AddInfluxDb2AppMetrics(builder.Configuration);

4 - Tambahkan ini setelah builder.Build() :

 app.UseRequestsCounterMiddleware();
app.UseRequestsDurationMiddleware();
app.UseResponsesSizeMiddleware();
app.UseResponsesApdexMiddleware();
app.UseMetricsAllMiddleware();
app.UseMetricsAllEndpoints();

5 - Tambahkan ini sebelum app.Run() :

 app.UseHttpStatusCodesCounterMiddleware();

Cara menambahkan middleware metrik baru:

1 - Buat middleware pencegat;

2 - Suntikkan IMetrics ;

 public class MyNewMetricMiddleware
{
    private readonly RequestDelegate _next;
    private readonly IMetrics _metrics;

    public MyNewMetricMiddleware(RequestDelegate next, IMetrics metrics)
    {
        _next = next;
        _metrics = metrics;
    }

    public async Task InvokeAsync(HttpContext context)
    {
        try
        {
            await _next(context);

            var tags = new MetricTags
            (
                new[] { "Tag1-Key", "Tag2-Key" },
                new[] { "Tag1-Value, "Tag2-Value }
            );

            _metrics.Measure.Counter.Increment
            (
                new CounterOptions
                {
                    Name = "my-new-metric",
                    Context = "my-new-context",
                    MeasurementUnit = Unit.Calls,
                    Tags = tags
                }
            );
        }
        catch (Exception ex)
        {
        }
    }
}

3 - Tambahkan middleware ke saluran aplikasi:

 builder.UseMiddleware();

Cara menambahkan metrik baru di pengontrol:

1 - Suntikkan IMetrics ke pengontrol:

 public WeatherForecastController(ILogger logger, IMetrics metrics)
{
    _logger = logger;
    _metrics = metrics;
}

2 - Gunakan IMetrics :

Get() { var tags = new MetricTags ( new[] { "Tag1-Key", "Tag2-Key" }, new[] { "Tag1-Value, "Tag2-Value } ); _metrics.Measure.Counter.Increment ( new CounterOptions { Name = "my-new-metric", Context = "my-new-context", MeasurementUnit = Unit.Calls, Tags = tags } ); return Enumerable.Range(1, 5).Select ( index => new WeatherForecast { Date = DateOnly.FromDateTime(DateTime.Now.AddDays(index)), TemperatureC = Random.Shared.Next(-20, 55), Summary = Summaries[Random.Shared.Next(Summaries.Length)] } ) .ToArray(); }">

 [HttpGet(Name = "GetWeatherForecast")]
public IEnumerable Get()
{
    var tags = new MetricTags
    (
        new[] { "Tag1-Key", "Tag2-Key" },
        new[] { "Tag1-Value, "Tag2-Value }
    );
    
    _metrics.Measure.Counter.Increment
    (
        new CounterOptions
        {
            Name = "my-new-metric",
            Context = "my-new-context",
            MeasurementUnit = Unit.Calls,
            Tags = tags
        }
    );

    return Enumerable.Range(1, 5).Select
        (
            index => new WeatherForecast
            {
                Date = DateOnly.FromDateTime(DateTime.Now.AddDays(index)),
                TemperatureC = Random.Shared.Next(-20, 55),
                Summary = Summaries[Random.Shared.Next(Summaries.Length)]
            }
        )
        .ToArray();
}
