Conventions used

There are a number of text conventions used throughout this book.

CodeInText: 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: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

POST _analyze
{
  "tokenizer": "standard",
 "text": "Tokenizer breaks characters into tokens!"
}

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

GET /amazon_products/_search
{
  "query": {
    "term": {
      "manufacturer.raw": "victory multimedia"
    }
  }
}

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

$> tar -xzf filebeat-7.0.0-linux-x86_64.tar.gz
$> cd filebeat

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: "Click on the Management icon on the left-hand menu and then click on License Management."
