SHOW PLUGINS syntax

SHOW PLUGINS

Displays all the loaded plugins and UDFs. “Type” column should be one of the udf, ranker, index_token_filter, or query_token_filter. “Users” column is the number of thread that are currently using that plugin in a query. “Extra” column is intended for various additional plugin-type specific information; currently, it shows the return type for the UDFs and is empty for all the other plugin types.
