Hi all 1. When I install logstash-codec-sflow with bin/logstash-plugin install logstash-codec-sflow I get: Validating Installing Install Successful I then do a bin/logstash-plugin list --installed and all the plugins show including sflow. I do this while the logstash service is stopped (just thought this would be best) Startup the logstash service sudo service logstash start - It starts, tail the logs (Have loginfo set to trace) to see what is going on and see all but the sflow plugin listed as loaded plugins. Go back to bin/logstash-plugin list --installed and get Error: No plugins installed Then I downloaded the plugin manually - same approach as above instead specifying the path to the file (incl the file name) Installing (doesnt validate "local" plugins) Installation Successful bin/logstash-plugin list --installed See it there Startup Logstash Logs: No sflow Go back - bin/logstash-plugin list --installed If I run above without sudo I get: `/usr/share/logstash$ bin/logstash-plugin list --installed Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release. unsupported Java version "10", defaulting to 1.7 WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.jruby.util.io.FilenoUtil to method sun.nio.ch.SelChImpl.getFD() WARNING: Please consider reporting this to the maintainers of org.jruby.util.io.FilenoUtil WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release` Run it with sudo: ``` XXXXXX:/usr/share/logstash$ sudo bin/logstash-plugin list --installed [sudo] password for XXXXX: logstash-codec-cef logstash-codec-collectd logstash-codec-dots logstash-codec-edn logstash-codec-edn_lines logstash-codec-es_bulk logstash-codec-fluent logstash-codec-graphite logstash-codec-json logstash-codec-json_lines logstash-codec-line logstash-codec-msgpack logstash-codec-multiline logstash-codec-netflow logstash-codec-plain logstash-codec-rubydebug logstash-filter-aggregate logstash-filter-anonymize logstash-filter-cidr logstash-filter-clone logstash-filter-csv logstash-filter-date logstash-filter-de_dot logstash-filter-dissect logstash-filter-dns logstash-filter-drop logstash-filter-elasticsearch logstash-filter-fingerprint logstash-filter-geoip logstash-filter-grok logstash-filter-jdbc_static logstash-filter-jdbc_streaming logstash-filter-json logstash-filter-kv logstash-filter-metrics logstash-filter-mutate logstash-filter-ruby logstash-filter-sleep logstash-filter-split logstash-filter-syslog_pri logstash-filter-throttle logstash-filter-translate logstash-filter-truncate logstash-filter-urldecode logstash-filter-useragent logstash-filter-xml logstash-input-azure_event_hubs logstash-input-beats logstash-input-dead_letter_queue logstash-input-elasticsearch logstash-input-exec logstash-input-file logstash-input-ganglia logstash-input-gelf logstash-input-generator logstash-input-graphite logstash-input-heartbeat logstash-input-http logstash-input-http_poller logstash-input-imap logstash-input-jdbc logstash-input-kafka logstash-input-pipe logstash-input-rabbitmq logstash-input-redis logstash-input-s3 logstash-input-snmptrap logstash-input-sqs logstash-input-stdin logstash-input-syslog logstash-input-tcp logstash-input-twitter logstash-input-udp logstash-input-unix logstash-output-cloudwatch logstash-output-csv logstash-output-elasticsearch logstash-output-email logstash-output-file logstash-output-graphite logstash-output-http logstash-output-kafka logstash-output-lumberjack logstash-output-nagios logstash-output-null logstash-output-pagerduty logstash-output-pipe logstash-output-rabbitmq logstash-output-redis logstash-output-s3 logstash-output-sns logstash-output-sqs logstash-output-stdout logstash-output-tcp logstash-output-udp logstash-output-webhdfs ``` Um no logstash-codec-sflow..... just amoment ago you told me it was installed (logstash service stopped when installing, then started the service and ran command above) I have run a update on all these plugins (painful wish there was or knew how to do --all for update ...) sflow is on 2.0.2 which is also the latest version on the [download.](https://rubygems.org/gems/logstash-codec-sflow/versions/2.0.2) Environment: **OS** - `Ubuntu 18.10 on x64 Physical server` **Whole ELK stack** - `6.4.1` **ruby** - `ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux] ruby in vendor/bundle/ 2.3.0` **jruby** - `unsupported Java version "10", defaulting to 1.7 jruby 9.1.13.0 (2.3.3) 2017-10-04 fffffff Java HotSpot(TM) 64-Bit Server VM 10.0.2+13 on 10.0.2+13 +jit [linux-x86_64]` **Java** `:/usr/share/logstash$ java -version java version "1.8.0_181" Java(TM) SE Runtime Environment (build 1.8.0_181-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)` I know it says Java 10 isn't supported but it defaults to 1.7 now not sure if logstash needs min 1.8 (which is installed) Any insight or help here? ---
