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: “We will be using pandas for data manipulation and structuring, matplotlib and seaborn for plotting graphs, tqdm for visualizing iteration progress, and lingua for text language detection.”

A block of code is set as follows:

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
from tqdm import tqdm
from lingua import Language, LanguageDetectorBuilder
tqdm.pandas()

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

sudo systemctl start node_exporter sudo systemctl start prometheus

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: “We can set up the Prometheus link now by clicking on the three-line button on the top-left tab and clicking on the Data Sources tab under the Administration dropdown.”
