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

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]]
  ## files to tail.
  ## These accept standard unix glob matching rules, but with the addition of
  ## ** as a "super asterisk". ie:
  ##   "/var/log/**.log"  -> recursively find all .log files in /var/log
  ##   "/var/log/*/*.log" -> find all .log files with a parent dir in /var/log
  ##   "/var/log/apache.log" -> just tail the apache log file
  ##
  ## See https://github.com/gobwas/glob for more examples
  ##
  files = ["/var/mymetrics.out"]
  ## Read file from beginning.
  from_beginning = false

  ## Data format to consume.
  ## Each data format has it's own unique set of configuration options, read
  ## more about them here:

  data_format = "influx"
