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 function used to get this information is the rate() function.”

A block of code is set as follows:

histogram_quantile(
    0.95, sum(
        rate(
            http_server_duration_milliseconds_bucket{}[$__rate_interval])
        ) by (le)
    )

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

$ helm upgrade owg open-telemetry/opentelemetry-collector -f OTEL-Collector.yaml

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: “From the dashboard’s Settings screen, you can add or remove tags from individual dashboards.”
