![]() It makes your application back-end agnostic and provides a consistent way to export data for all your applications. The recommended way is to use the collector to export data. Using the OpenTelemetry Collector (recommended) There are 2 ways to export data from OpenTelemetry: Shell copy dotnet tool install -global dotnet-countersĭotnet counters monitor -process-id 123 -counters MyApplication Then, you can use the following command to get the metrics: You can install it using dotnet tool install -global dotnet-counters or direct download link. Using Meter also allows you to monitor the application using dotnet counters or dotnet monitor. For example, using the following logger method, you could query all names containing a specific value requested within a specific time range.Ĭ# copy var builder = WebApplication.CreateBuilder(args) Īpp.MapGet( "/", (ILogger logger, string name) => This enables logging providers to store the parameter values as fields, which is useful to query your logs later. It supports structured logging, the arguments themselves are passed to the logging system, not just the formatted message template.

That's being said, you can still instrument your application manually if you want to. This means you can use OpenTelemetry to monitor your application and get insights even if you don't manually instrument your application. You can use OpenTelemetry.Instrumentation.* packages to collect data from common sources: Also, there are lots of libraries that provides instrumentation for OpenTelemetry. NET code that use objects from these namespaces to instrument the code are already instrumented for OpenTelemetry. Instead you can use types provided in System.Diagnostics and. Instead, you don't need to use an OpenTelemetry library. Instrumenting the code for OpenTelemetry in. OpenTelemetry defines 3 concepts when instrumenting an application:Įxample of metrics in Grafana #Code instrumentation It could be the service name, the service instance, or the service version.
