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: "Let's use tcpdump to collect on my en0 interface, capturing full-sized packets (-s), and saving the file to local-capture.pcap."
A block of code is set as follows:
{
  "acknowledged" : true,
  "shards_acknowledged" : true,
  "index" : "my-first-index"
}
Any command-line input or output is written as follows:
$ curl -X PUT "localhost:9200/my-first-index?pretty"
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "The Administration interface is seemingly fairly sparse, but it allows you to drill down into detailed configurations for the security policies for the Elastic Agent."
