Reads log file lines that have not been read.

Project description

A python “port” of logcheck’s logtail2.

Pygtail reads log file lines that have not been read. It will even handle log files that have been rotated.

Usage

From the command line:

Usage: pygtail.py [options] logfile

Print log file lines that have not been read.

Options:
  -h, --help            show this help message and exit
  -o OFFSET_FILE, --offset-file=OFFSET_FILE
                        File to which offset data is written (default:
                        <logfile>.offset).
  -p, --paranoid        Update the offset file every time we read a line
                        (as opposed to only when we reach the end of the
                        file).
  -n N, --every-n=N     Update the offset file every N'th time we read a
                        line (as opposed to only when we reach the end of
                        the file).
  --no-copytruncate     Don't support copytruncate-style log rotation.
                        Instead, if the log file shrinks, print a warning.
  --read-from-end       Read log file from the end if offset file is
                        missing. Useful for large files.
  --log-pattern         Custom log rotation glob pattern. Use %s to
                        represent the original filename. You may use this
                        multiple times to provide multiple patterns.
  --full_lines          Only log when line ends in a newline `\n`
                        (default: False)
  --version             Print version and exit.

In your code:

from pygtail import Pygtail

for line in Pygtail("some.log"):
    sys.stdout.write(line)
