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 an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You can change this by logging in to the server with SSH using both username and password as conf and running the NETCONF utility."

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

check_mysql -H $HOSTADDRESS$ -u myhrmuser -p myhrmpassword -d HRM

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: "When creating a new SNMP service, enter the name of your host in the Example Host field and click on SNMP Walk to scan the host."
