Simple Fluentd Plugin to count number of messages and outputs to log

<filter foo.bar.**>
  type flowcounter_simple
  unit second
</filter>

This filter plugin pass through records, and writes counts into the log file as

plugin:out_flowcounter_simple  count:30  indicator:num  unit:second

<match foo.bar.**>
  type flowcounter_simple
  unit second
</match>

This plugin does not emit, just writes counts into the log file as

plugin:out_flowcounter_simple  count:30  indicator:num  unit:second

• unit

  One of second/minute/hour/day. Default: minute

• indicator

  One of num/byte. Default: num

• comment

  Just a comment. You may use this to mark where you put flowcounter_simple.

There is a fluent-plugin-flowcounter, but I needed a very very simple plugin to use for performance evaluation.
