tail Input Plugin

The tail plugin "tails" a logfile and parses each log message.

By default, the tail plugin acts like the following unix tail command:

tail --follow=name --lines=0 --retry myfile.log

• --follow=name means that it will follow the name of the given file, so that it will be compatible with log-rotated files.
• --lines=0 means that it will start at the end of the file (unless the from_beginning option is set).
• --retry means it will retry on inaccessible files.

see http://man7.org/linux/man-pages/man1/tail.1.html for more details.

The plugin expects messages in one of the Telegraf Input Data Formats.

Configuration:

# Stream a log file, like the tail -f command
[[inputs.tail]]
