# Getting Started with OpenTelemetry .NET in 5 Minutes
|
||||
|
||||
First, download and install the [.NET Core
|
||||
SDK](https://dotnet.microsoft.com/download) on your computer.
|
||||
|
||||
Create a new console application and run it:
|
||||
|
||||
```sh
|
||||
dotnet new console --output getting-started
|
||||
cd getting-started
|
||||
dotnet run
|
||||
```
|
||||
|
||||
You should see the following output:
|
||||
|
||||
```text
|
||||
Hello World!
|
||||
```
|
||||
|
||||
Install the
|
||||
[OpenTelemetry.Exporter.Console](../../../src/OpenTelemetry.Exporter.Console/README.md)
|
||||
package:
|
||||
|
||||
```sh
|
||||
dotnet add package OpenTelemetry.Exporter.Console
|
||||
```
|
||||
|
||||
Update the `Program.cs` file with the code from [Program.cs](./Program.cs):
|
||||
|
||||
Run the application again (using `dotnet run`) and you should see the metric
|
||||
output from the console, similar to shown below:
|
||||
|
||||
<!-- markdownlint-disable MD013 -->
|
||||
```text
|
||||
Export[] 16:38:36.241 16:38:37.233 TestMeter:counter [tag1=value1;tag2=value2] SumMetricAggregator Value: 590, Details: Delta=True,Mon=True,Count=59,Sum=590
|
||||
Export[] 16:38:37.233 16:38:38.258 TestMeter:counter [tag1=value1;tag2=value2] SumMetricAggregator Value: 640, Details: Delta=True,Mon=True,Count=64,Sum=640
|
||||
Export[] 16:38:38.258 16:38:39.261 TestMeter:counter [tag1=value1;tag2=value2] SumMetricAggregator Value: 640, Details: Delta=True,Mon=True,Count=64,Sum=640
|
||||
Export[] 16:38:39.261 16:38:40.266 TestMeter:counter [tag1=value1;tag2=value2] SumMetricAggregator Value: 630, Details: Delta=True,Mon=True,Count=63,Sum=630
|
||||
Export[] 16:38:40.266 16:38:41.271 TestMeter:counter [tag1=value1;tag2=value2] SumMetricAggregator Value: 640, Details: Delta=True,Mon=True,Count=64,Sum=640
|
||||
```
|
||||
<!-- markdownlint-enable MD013 -->
|
||||
|
||||
Congratulations! You are now collecting metrics using OpenTelemetry.
|
||||
|
||||
What does the above program do?
|
||||
|
||||
The program creates a
|
||||
[Meter](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md#meter)
|
||||
instance named "TestMeter" and then creates a
|
||||
[Counter](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md#counter)
|
||||
instrument from it. This counter is used to repeatedly report metric
|
||||
measurements until exited after 10 seconds.
|
||||
|
||||
An OpenTelemetry
|
||||
[MeterProvider](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md#meterprovider)
|
||||
is configured to subscribe to instruments from the Meter `TestMeter`, and
|
||||
aggregate the measurements in-memory. The pre-aggregated metrics are exported
|
||||
every 1 second to a `ConsoleExporter`. `ConsoleExporter` simply displays it on
|
||||
the console.

The query language allows filtering and aggregation based on these dimensions. Changing any label value, including adding or removing a label, will create a new time series.

[](https://www.nuget.org/packages/OpenTelemetry.Exporter.Prometheus)
|
||||
[](https://www.nuget.org/packages/OpenTelemetry.Exporter.Prometheus)
|
||||
|
||||
## Prerequisite
|
||||
|
||||
* [Get Prometheus](https://prometheus.io/docs/introduction/first_steps/)
|
||||
|
||||
## Installation
|
||||
|
||||
```shell
|
||||
dotnet add package OpenTelemetry.Exporter.Prometheus
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
You can configure the `PrometheusExporter` by following the directions below:
|
||||
|
||||
* `Url`: The url to listen to. Typically it ends with `/metrics` like `http://localhost:9184/metrics/`.
|
||||
|
||||
See
|
||||
[`TestPrometheusExporter.cs`](../../examples/Console/TestPrometheusExporter.cs)
|
||||
for example use.
|
||||
|
||||
## References
