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 are shown as follows: “We can include other contexts through the use of the include directive.”

A block of code is set as follows:

agent.sinks.k1.hdfs.path=/logs/apache/access
agent.sinks.k1.hdfs.filePrefix=access
agent.sinks.k1.hdfs.fileSuffix=.log

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

agent.sources.s1.command=uptime
agent.sources.s1.restart=true
agent.sources.s1.restartThrottle=60000

 $ tar -zxf apache-flume-1.3.1.tar.gz ...
