logburn

logburn is a fast log analysis tool for parsing logs realtime.

Installation

If you don't have it, install Crystal:

curl -sSL https://dist.crystal-lang.org/apt/setup.sh | sudo bash
sudo apt install crystal

For other distributions and other operating systems, refer to crystal-lang.

Then clone the repo and install:

git clone https://github.com/PenguinOwl/logburn
cd logburn
shards build
sudo ln -s $(pwd)/bin/logburn /usr/bin/

Usage

To add new profiles and errors, edit the configuration file and rebuild using shards build.

The configuration file needs to be formatted like this:

# The name of the profile
my_profile:
  # The name of the first item to match
  my_first_error:
    # A regular expression to match from the log
    regex: /ERROR-(\d+)/
    # Color to display in log, avaible colors are: red, green, yellow, blue, magenta, cyan
    color: red
    # The severity of the match, avaible severities are: moniter, low, medium, high (moniter is not shown in the reports)
    severity: low
    # If your error uses a error code, this is the matching group of an identifying id in the regex, use 0 for the whole match
    id: 1
    # Only include if you want your error to be hidded from display (it will still be logged)
    # hide: true
  my_second_error:
    regex: /Info/
    color: blue
    severity: moniter
    hide: true
