How to enable fluentD sumologic plugin

Question

I am trying to forward the logs from fluentD to summologic.

I have the following configuration in fluentd.conf

 <source>
  @type forward
  port 24224
  bind 0.0.0.0
</source>

  <match *.*>
      @type sumologic
      endpoint https://collectors.us2.sumologic.com/receiver/v1/http/XXXXX
      log_format json
      source_category AppLog
      source_name FluentD
      open_timeout 10
    </match>

While loading the docker contaier I get error as

config error file="/fluentd/etc/fluent.conf" error_class=Fluent::ConfigError error="Unknown output plugin 'sumologic'. Run 'gem search -rd fluent-plugin' to find plugins"

I request for the help to resolve the issue.
