Output metric count increments incorrectly

[komal-SkyNET]

I'm using '<match>' with '<store>' to count output records metrics.
Using fluentd-v0.14.25; fluent-plugin-elasticsearch (2.11.10); fluent-plugin-prometheus (1.1.0), fluent-plugin-bufferize (0.0.2).

So I have something like this:

<match> 
   <store> @type elasticsearch </store>
   <store> @type prometheus <metric>....</metric></store>
</match>

The problem is that my output metric count increases despite an elasticsearch(i.e, first store tag) delivery failure.
