Problem

[error]: config error file="/etc/fluent/fluent.conf" error_class=Fluent::ConfigError error="Unknown filter plugin 'concat'. Run 'gem search -rd fluent-plugin' to find plugins"

Steps to replicate

here is my part config:

<filter kubernetes.**>
@type concat
key log
multiline_end_regexp /\n$/
separator ""

If I comment out this configuration, fluentd words fine, why fluentd can't find this plugin, while other plugins work fine

Expected Behavior

Your environment

  • docker linux x86_64 3.10.0-967.27.2.el7.x86_64
  • fluentd 1.3.3
  • fluent-plugin-concat 2.5.0
