Fluentd fails to load separate gems with same @type name

Describe the bug

I have installed two splunk gems, namely, fluent-plugin-splunk-enterprise and fluent-plugin-splunk-hec. Both the gems (even though 2 separate gems) have types with same name splunk_hec. Even though the type names are same, they have different parameters, that makes them distinct. But when I use @type splunk_hec in my fluentd configuration with the parameters of fluent-plugin-splunk-enterprise, it fails to recognize them and throws below error:

2025-11-06 17:05:28 +0000 [error]: config error file="/etc/fluent/fluentd.conf" error_class=Fluent::ConfigError error="'hec_token' parameter is required"

It asks for hec_token, which is basically a parameter of fluent-plugin-splunk-hec and not fluent-plugin-splunk-enterprise.

To Reproduce

This bug can be reproduced by simply installing both these gems:

• fluent-gem install fluent-plugin-splunk-hec
• fluent-gem install fluent-plugin-splunk-enterprise

Fluentd will automatically register the @type name from first gem and ignore the second one. (which is happening in my case)

Expected behavior

Now, I do understand that this is a known behavior of fluentd and it has been like that for some time. So, this understanding brings me to a question that is there a workaround for this without having to remove any one of the 2 gems?

Is there a way that we can install both gems and use them in our configuration without conflicting with each other??

Your Environment

- Fluentd version: 1.19.0
- Package version: 6.0.0
- Operating system: Rocky 8
- Kernel version: 5

Your Configuration

<match splunk.**>
  @type splunk_hec
  protocol http
  host "example.com"
  port 8088
  token 00000000-0000-0000-0000-000000000000
  sourcetype "_json"
  <buffer>
    @type memory
    flush_interval 10s
    retry_max_times 2
    retry_wait 1s
  </buffer>
</match>

Your Error Log

2025-11-06 17:05:28 +0000 [error]: config error in:
<match splunk.**>
  @type splunk_hec
  protocol http
  host "example.com"

Additional context

I am well aware of the workaround by forking the fluent-plugin-splunk-enterprise and renaming the type, and then building the gem. But this workaround is not feasible and convenient for my use case. I am much interested in a solution where fluentd handles this internally or we handle it internally without having to make modifications in the gem.
