While installing plugin using logstash-plugin its says successful  
`logstash/bin# ./logstash-plugin install logstash-filter-naxsi-0.9.2.gem Validating logstash-filter-naxsi-0.9.2.gem Installing logstash-filter-naxsi Installation successful`

But the list doesn't show the plugin listed:  
`logstash/bin# ./logstash-plugin list | grep naxsi`

While I'm trying to use the filter plugin its says:  
`logstash/bin# logstash -f /opt/logstash/logstash.conf  
Sending Logstash's logs to /var/log/logstash which is now configured via log4j2.properties  
06:48:44.243 [LogStash::Runner] ERROR logstash.agent - fetched an invalid config {:config=\>"input {\n kafka {\n bootstrap\_servers =\> "kafka\_dc2:9095"\n topics =\> ["naxsi\_log"]\n }\n}\n\nfilter {\n naxsi {}\n}\n\noutput {\n elasticsearch {\n hosts =\> ["elasticsearch:9200"]\n }\n stdout { codec =\> rubydebug }\n}\n\n", :reason=\>"Couldn't find any filter plugin named 'naxsi'. Are you sure this is correct? Trying to load the naxsi filter plugin resulted in this error: LoadError"}```

`logstash/bin# logstash -V logstash 5.0.2`

I'd be surprised if it is compatible with 5.0 based on the lack of activity at [https://github.com/nextgxdx/logstash-filter-naxsi](https://github.com/nextgxdx/logstash-filter-naxsi)
