Fluent::Plugin::ColorStripper

An out plugin for Fluentd to strip ANSI color from log files. No more nasty logs from apps that use color that appear similar to:

[0;33;49mWARN [0m : [0;33;49mRate limit of 6 notifications per hour met for Http monitor 'test' for 'server
'[0m

You can specify all or specific fields to have the ANSI color stripped

Installation

$ gem install fluent-plugin-color-stripper

<match input.tag>
    @type color_stripper
    tag  output.tag
    strip_fields key1, key2
</match>

Pass this record:

input.tag: {
    "key1": "\033[30mvalue1\033[0m",
    "key2": "\033[31mvalue2\033[0m"
    "key3": "\033[32mvalue3\033[0m"
}

Then you get:

output.tag: {
    "key1": "value1",
    "key2": "value2",
    "key3": "\033[32mvalue3\033[0m"
}

If the field strip_fields is omitted or is empty then all fields will have their color stripped.

<match input.tag>
    @type color_stripper
    tag  output.tag
</match>

Pass this record:

input.tag: {
    "key1": "\033[30mvalue1\033[0m",
    "key2": "\033[31mvalue2\033[0m"
    "key3": "\033[32mvalue3\033[0m"
}

Then you get:

output.tag: {
    "key1": "value1",
    "key2": "value2",
    "key3": "value2"
}
