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: "What we need to do is just uncomment the one pipeline that is defined in the configuration file, located in the /etc/logstash folder."
A block of code is set as follows:
<memoryBacking> <locked/> </memoryBacking>
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
POWER TTWU_QUEUE NO_FORCE_SD_OVERLAP RT_RUNTIME_SHARE NO_LB_MIN NUMA NUMA_FAVOUR_HIGHER NO_NUMA_RESIST_LOWER
Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "After you push the Refresh button, new data should appear on the page."
