Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and explanations of their meanings.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Save the file in the /usr/src folder."

A block of code is set as follows:

# vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix

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

# yum install mysql-server zabbix-server-mysql

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "The Media tab is the place where the user can add the media that he or she wants to use to get notifications."

Note
