Long time user here, love Elasticstack but cant get over this problem. Trying to create input for protobuf. Input stanza below. LS stops after throwing java exception, cant get pass this -tried to get this to work in 7.x, no love -upgraded to 8.1 yesterday to see if this solves problem but still exists. -tried ruby comipled rb file and then google compiled rb file. -tried different options, but no effect -latest try today with same results as 7.x Searched online for solution, usually can overcome these with Google fu, but protobuf codec doesn't seem to have a lot of examples, besides kafka and even that is replicated on different sites. Details are; Centos7 uname -a Linux 3.10.0-1160.42.2.el7.x86\_64 #1 SMP Tue Sep 7 14:49:57 UTC 2021 x86\_64 x86\_64 x86\_64 GNU/Linux java --version openjdk 17.0.1 2021-10-19 OpenJDK Runtime Environment 21.9 (build 17.0.1+12) OpenJDK 64-Bit Server VM 21.9 (build 17.0.1+12, mixed mode, sharing) yum info Elasticsearch logstash kibana Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile - base: mirrors.mit.edu - epel: mirror.dst.ca - extras: [mirror.centos.iad1.serverforge.org](http://mirror.centos.iad1.serverforge.org) - updates: mirrors.seas.harvard.edu Installed Packages Name : Elasticsearch Arch : x86\_64 Version : 8.0.1 Release : 1 Size : 1.0 G Repo : installed From repo : Elasticsearch-8.x Summary : Distributed RESTful search engine built for the cloud URL : [https://www.elastic.co/](https://www.elastic.co/) License : Elastic License Description : Reference documentation can be found at : [Elasticsearch Guide [8.0] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html) : and the 'Elasticsearch: The Definitive Guide' book can be found at : [Elasticsearch: The Definitive Guide [2.x] | Elastic](https://www.elastic.co/guide/en/elasticsearch/guide/current/index.html) Name : kibana Arch : x86\_64 Version : 8.0.1 Release : 1 Size : 726 M Repo : installed From repo : Elasticsearch-8.x Summary : Explore and visualize your Elasticsearch data URL : [https://www.elastic.co](https://www.elastic.co) License : Elastic License Description : Explore and visualize your Elasticsearch data Name : logstash Arch : x86\_64 Epoch : 1 Version : 8.0.1 Release : 1 Size : 601 M Repo : installed From repo : Elasticsearch-8.x Summary : An extensible logging pipeline URL : [Logstash: Collect, Parse, Transform Logs | Elastic](https://www.elastic.co/logstash) License : Elastic License Description : An extensible logging pipeline Config snippet of logstash input stanza ````http host => "0.0.0.0" # default: 0.0.0.0 port => 9280 # default: 8080 tags => "PB_analytics" codec => protobuf { class_name => "com.ramp.analytics.proto.PacketWrapper" class_file => '/usr/share/logstash/protobuf/analytics_pb-3-5-0.rb' protobuf_root_directory => "/usr/share/logstash/protobuf/" protobuf_version => 3 } threads => 4 type => "protobuf_http" }``` /usr/share/logstash/bin/logstash-plugin list --verbose | grep protobuf OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release. logstash-codec-protobuf (1.2.5) ERROR in /var/log/logstash/logstash-plain.log ```[2022-03-05T11:30:55,049][INFO][logstash.runner] Starting Logstash {"logstash.version"=>"8.0.1", "jruby.version"=>"jruby 9.2.20.1 (2.5.8) 2021-11-30 2a2962fbd1 OpenJDK 64-Bit Server VM 11.0.13+8 on 11.0.13+8 +indy +jit [linux-x86_64]"} [2022-03-05T11:30:55,051][INFO][logstash.runner] JVM bootstrap flags: [-Xms1g, -Xmx1g, -XX:+UseConcMarkSweepGC, -XX:CMSInitiatingOccupancyFraction=75, -XX:+UseCMSInitiatingOccupancyOnly, -Djava.awt.headless=true, -Dfile.encoding=UTF-8, -Djruby.compile.invokedynamic=true, -Djruby.jit.threshold=0, -Djruby.regexp.interruptible=true, -XX:+HeapDumpOnOutOfMemoryError, -Djava.security.egd=file:/dev/urandom, -Dlog4j2.isThreadContextMapInheritable=true, --add-opens=java.base/java.security=ALL-UNNAMED, --add-opens=java.base/java.io=ALL-UNNAMED, --add-opens=java.base/java.nio.channels=ALL-UNNAMED, --add-opens=java.base/sun.nio.ch=ALL-UNNAMED, --add-opens=java.management/sun.management=ALL-UNNAMED] [2022-03-05T11:30:56,431][INFO][logstash.agent] Successfully started Logstash API endpoint {:port=>9600, :ssl_enabled=>false} [2022-03-05T11:30:57,955][INFO][org.reflections.Reflections] Reflections took 74 ms to scan 1 urls, producing 120 keys and 417 values [2022-03-05T11:30:59,082][ERROR][logstash.codecs.protobuf] Unable to load file: /usr/share/logstash/protobuf/analytics_pb-3-5-0.rb.

The only thing I found online is from this link [here](https://github.com/logstash-plugins/logstash-codec-protobuf/issues/41), from 2019 This error is caused by an incompatibility between your protoc version (probably 3.7?) and the rather old jruby implementation that is shipped with this codec. The problem is that the jruby version is not well maintained and we cannot easily update it ourselves. We're looking into this though. In the meantime you can workaround this by using the 3.5.0 version of protoc. ---
