Plugin Helper: Event Loop
The event_loop plugin helper manages event loops.
Here is an example:
1
require 'fluent/plugin/input'
2
​
3
module Fluent::Plugin
4
class ExampleInput < Input
5
Fluent::Plugin.register_input('example', self)
6
​
7
# 1. Load `event_loop_helper`
8
helpers :event_loop
9
​
10
# Omit `configure`, `shutdown` and other plugin APIs
11
​
12
def start
13
super
14
​
15
# 2. Attach watcher
16
watcher = Coolio::TCPServer.new(...)
17
event_loop_attach(watcher)
18
end
19
end
20
end
Copied!
The attached watcher is managed by the plugin. No need of watcher detach code in plugin's shutdown. The plugin shutdowns the attached watchers automatically.
