I'm having trouble installing the plugin contrib in logstash . It returns me the following error: **plugin contrib does not exist.** Can someone help me?

Thank you.

First I go to the logstash installation directory, / opt / logstash and I type the command bin/plugin install contrib.

Now is returning me the error: ERROR: File /opt/logstash/Gemfile does not exist or is not writable, aborting.

There is no plugin named "contrib". Where did you read about that?

Are you running the command as yourself rather than as root?

I read about the "contrib" on a website talking about elk stack. It tells me I need this plugin to be able to run the filters, such as grok, match, grep. To use them a specific plugin is necessary?

That information is very outdated and the grep filter is deprecated since at least two years. Most filters you'll need all included and the rest can be installed by following the instructions on [elastic.co](http://elastic.co).
