Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “The Zookeeper configuration is not shown as it is identical to the first docker compose file.”

A block of code is set as follows:

using OpenTelemetry.Metrics;
using OpenTelemetry;
using System.Diagnostics.Metrics;
var meter = new Meter("NameOfMeter");
var counter = meter.CreateCounter<int>(Name: "requests-
  received", Unit: "requests", Description: "Number of
    requests the service receives");

Any command-line input or output is written as follows:

dotnet add package System.Diagnostics.DiagnosticSource
dotnet add package OpenTelemetry.Instrumentation
  .EventCounters --prerelease

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Be sure to uncheck the Use controllers checkbox to use minimal APIs if using the new project dialog from Visual Studio.”
