In this book, you will find a number of text styles 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: "For instance, in Cisco log files there is a src_ip field."

A block of code is set as follows:

[mySourcetype] 
REPORT-fields = myLinuxScript_fields

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[myUnstructured] 
DATETIME_CONFIG = 
NO_BINARY_CHECK = true 
category = Custom 
pulldown_type = true

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

ssh -v -p 8089 mydeploymentserver.com

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "The most common messages we see are things like unauthorized login attempt <user> or Connection Timed out to <ip address>."
