Hi folks. I'm not sure what happened, but yesterday my ELK was logging, and today it isn't. I tried to check the configs on one of the Logstash nodes, and I get an error about loading logstash/runner:
sudo /opt/logstash/bin/logstash --verbose -f /etc/logstash-forwarder.conf LoadError: no such file to load -- logstash/runner require at org/jruby/RubyKernel.java:1040 (root) at /opt/logstash/lib/bootstrap/environment.rb:57
I get a similar error if I just try to run logstash:
/opt/logstash/bin/logstash LoadError: no such file to load -- logstash/runner require at org/jruby/RubyKernel.java:1040 (root) at /opt/logstash/lib/bootstrap/environment.rb:57
/var/log/logstash/logstash.err contains the same.
The server is Ubuntu 14.04
Logstash version is Version: 1:2.1.3-1
