As we have already discussed the various type of plugins available in Logstash, let's understand how to list/install/update/remove a plugin using the logstash-plugin script, which is present within the bin folder of Logstash.
The usage of the plugin command-line option is as follows:
bin/logstash-plugin [OPTIONS] SUBCOMMAND [ARG]
The various subcommands are list, install, remove, update, pack, unpack, and generate.
list is used to list the installed plugins, install is used to install a plugin, remove is used to remove a plugin, update is used to update a plugin, pack is used to package already installed plugins and unpack is used to unpack packaged plugins.
To list all the plugins available in Logstash:
bin/logstash-plugin list
The various options available for list can be viewed using:
bin/logstash-plugin list --help
It displays options such as --installed, --verbose, --group NAME.
To find an installed plugin using its name:
