Deprecated : most of the tail-multiline features had been merged to main in_tail plugin. This plugin is not maintained anymore!!!!!
Fluent::Plugin::Tail-Multiline, a plugin for Fluentd
Tail-Multiline plugin extends built-in tail plugin with following features
- Support log with multiple line output such as stacktrace
- RegEx parameter to detect first line
- Save raw log data
built-in templates are not supported. It does not support multiple line log anyway
Use ruby gem as :
gem 'fluent-plugin-tail-multiline'
Or, if you're using td-client, you can call td-client's gem
$ /usr/lib64/fluent/ruby/bin/gem install fluent-plugin-tail-multiline
Tail-Multiline extends tail plugin.

It's too long format. You can rewrite above parameters with format{1..20}.
