Observability is the practice of understanding the internal state of a system by analyzing its outputs—primarily logs, metrics, and traces. In software, observability provides insights into the health, performance, and behavior of applications, services, and infrastructure, allowing teams to identify and resolve issues faster, optimize system performance, and improve user experience.

Key Components of Observability

Logs: Logs are records of events or messages generated by applications or infrastructure, often capturing errors, warnings, or significant operations. They help in understanding what actions occurred and in what sequence.
Metrics: Metrics are numerical values that represent the performance of a system, such as CPU usage, memory usage, response times, and throughput. Metrics help monitor trends and spot anomalies.
Traces: Traces follow a request’s path through different parts of the system, particularly in distributed or microservices architectures. They provide a deta

Get files from directory

string[] filePaths = Directory.GetFiles(@"C:\path\to\file");

foreach (var item in filePaths)
{
    Console.WriteLine(item);
}

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).
