Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

For that the OpenTelemetry SDK could be used.

Understand your systems like never before with traces and PostgreSQL
Maybe surprisingly, there doesn't seem to be an open source C client library for OpenTelemetry at the moment -- I'd guess that such a library would make introducing spans/traces in PostgreSQL a bit easier (although to be honest, I don't know/remember much about building and integrating C and C++).
(there is a C++ client[1], although they mention that support for C is not currently[2] a goal of the project -- and I couldn't find any other implementations elsewhere)

Guide to Distributed Tracing with OpenTelemetry Dotnet
💡Good to know -- If you wish to export traces to Jaeger, you should use the AddJaegerExporter instead of the AddOtlpExporter. Visit the opentelemetry-dotnet repository to see how it's done.

Observability with Grafana Cloud and OpenTelemetry in .net microservices
We're going to use OpenTelemetry .NET SDK. Add following nuget dependencies to the project:

OpenTelemetry in Action: Identifying Database Dependencies
We instrument the application with the OpenTelemetry SDK and SqlClient instrumentation library for .NET. First, we add the following NuGet package references to the API’s project file:
-
State for each API Request
It should be handled automatically by OpenTelemetry middlewares. Just look through documentation and samples https://github.com/open-telemetry/opentelemetry-dotnet

[c#] Using W3C Trace Context standard in distributed tracing
Besides that, the propagation fields (traceparent and tracestate) were added in the message header. In the last article, I said that the standard (in the Working Draft (WD) step of the w3c process) recommends to add the propagation fields in the application-properties section by the message publisher. For the current example, I chose to propagate that context in the message header even for AMQP calls as was done in the dotnet OpenTelemetry example. It's important to reinforce that Trace Context: AMQP protocol is not a W3C Recommendation yet. Take a look at the place where the propagation fields were added:

Tracing End-to-End Data from Power Apps to Azure Cosmos DB
As long as the Azure Functions app knows the instrumentation key from an Application Insights instance, it traces almost everything. OpenTelemetry.NET is one of the Open Telemetry implementations, has recently released v1.0 for tracing. Both metrics and logging are close to GA. However, it doesn't work well with Azure Functions. Therefore, in this post, let's manually implement the tracing at the log level, which is sent to Application Insights.
