I followed the installation steps but when I install the plugin it shows this error:
ERROR: Installation Aborted, message: Bundler could not find compatible versions for gem "logstash-core-plugin-api":

Running bundle update will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
Anyone knows why's that?
Thanks a lot!

Grok is included as part of the core LS release, you don't need to install it.

Thanks for your reply!
Is the logstash-input-file plugin included as part of the core LS release too?
