JF91.AppMetrics.InfluxDB2.Net7
1.0.0
J'ai créé ce package afin que vous puissiez facilement intégrer App.Metrics dans votre API WEB ASP pour envoyer les métriques collectées à un serveur InfluxDB2.
La configuration est très simple, installez simplement le package Nuget, ajoutez la section de configuration à votre appsettings.json et injectez les services dans votre program.cs.
Veuillez suivre attentivement les instructions.
Installez Nuget :
dotnet add package JF91.AppMetricsInfluxDB2 --version 1.2.0
appsettings.json
et modifiez-la selon vos besoins : "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",

},

1 - Créer un middleware intercepteur ;
2 - Injecter 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 - Ajoutez un middleware au pipeline d'application :
builder.UseMiddleware();
1 - Injectez IMetrics
dans le contrôleur :
public WeatherForecastController(ILogger logger, IMetrics metrics)
{
_logger = logger;
_metrics = metrics;
}
2 - Utilisez IMetrics
:
[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();
}
