Good morning. Recently we migrated the instances from Centos to Rocky Linux. We are suffering this problem: When we install logstash and before start it We try to add the plugins for pubsub(input and output) but the service doesn´t recognise the plugins. Logstash says that the plugin is not installed. ```auto [2024-05-10T09:37:36,106][ERROR][logstash.plugins.registry] Unable to load plugin. {:type=>"input", :name=>"google_pubsub"} [2024-05-10T09:37:36,197][ERROR][logstash.agent] Failed to execute action {:action=>LogStash::PipelineAction::Create/pipeline_id:meppubsub, :exception=>"Java::JavaLang::IllegalStateException", :message=>"Unable to configure plugins: (PluginLoadingError) Couldn't find any input plugin named 'google_pubsub'. ``` ```auto [2024-05-10T09:37:38,973][ERROR][logstash.plugins.registry] Unable to load plugin. {:type=>"output", :name=>"google_pubsub"} [2024-05-10T09:37:38,977][ERROR][logstash.agent] Failed to execute action {:action=>LogStash::PipelineAction::Create/pipeline_id:mepcdr, :exception=>"Java::JavaLang::IllegalStateException", :message=>"Unable to configure plugins: (PluginLoadingError) Couldn't find any output plugin named 'google_pubsub'.

I am beginning to suspect that it is the OS's fault but I have no choice as it is an image provided by my security department. Thnx in advance ---

Did you install the input and output plugins after installing logstash? Those plugins are not bundled in Logstash, so you need to install them. The documentation are [here](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-google_pubsub.html) and [here](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-google_pubsub.html). ---

Hi Leandro, yes, I´ve installed them after logstash instalation. I think I´ve found the issue. It´s related with the logstash user permissions. It worked since logstash user is in root group. Not recommended but effective anyway.
