sematext-metrics

A .Net Standard Client for Sematext Custom Metrics

A free account to generate API tokens is available at www.sematext.com

Installation

Package Manager

    Install-Package Sematext-Metrics

.Net CLI

    dotnet add package Sematext-Metrics

Initialization

Once you create an account and application via the sematext web ui you will have an app token to use when you initialize the MetricsClient

    var client = new MetricsClient(<YOUR APP TOKEN>);

Usage

Send a single metric

    // create a new metric
    var metric = new Metric(timestamp: TimeHelper.EpochFromUtc,
                            name: "coffee-consumed",
                            value: 4,
                            aggregateType: AggregateTypes.Sum,
                            filter1: "floor=1",
                            filter2: "strength=bold");

    // send the metric to sematext
    await client.SendAsync(metric);

Send multiple metrics

    // create a list to hold multple metrics
    var metrics = new List<Metric>();

    // create the first metric
    metrics.Add(new Metric(timestamp: TimeHelper.EpochFromUtc,
                            name: "coffee-consumed",
                            value: 4,
                            aggregateType: AggregateTypes.Sum,
                            filter1: "floor=1",
                            filter2: "strength=bold"));

    // create the second metric
    metrics.Add(new Metric(timestamp: TimeHelper.EpochFromUtc,
                            name: "coffee-consumed",
                            value: 1,
                            aggregateType: AggregateTypes.Sum,
                            filter1: "floor=3",
                            filter2: "strength=medium"));

    // send the metrics to sematext
    await client.SendAsync(metrics);

Configuration

To send metrics to a different api endpoint (if you are running an on-premise SPM setup) you can override the default endpoint when you initialize the MetricsClient

    var customEndpoint = new Uri("http://spm-receiver.example.com/spm-receiver/custom/receive.raw");
    var client = new MetricsClient(<YOUR APP TOKEN>, customEndpoint);

Running the unit tests

If you want to run the unit tests in the solution you first need to set an environment variable named SEMATEXT_APP_TOKEN. This environment variable is used in the TestCaseBase class when it creates the MetricsClient that is used to run the unit tests.

Powershell

    [Environment]::SetEnvironmentVariable("SEMATEXT_APP_TOKEN", "<YOUR APP TOKEN>", "User")
