I am updating from a 1.x installation to 2.3 on a CentOS 6 server. I removed the 1.x install using yum, saving the config files. I then installed 2.3 using this procedure: https://www.elastic.co/guide/en/logstash/current/installing-logstash.html#_yum. I checked logstash.log after starting the logstash service and saw this: Couldn't find any input plugin named 'collectd'. I followed the instructions from here: https://www.elastic.co/guide/en/logstash/current/working-with-plugins.html to add the collectd plug in, but the logstash-plugin executable seems to be missing:
[root@Analytics logstash]# logstash-plugin list
-bash: logstash-plugin: command not found
Is the logstash-plugin executable not included in the RPM? Or is it installed in some non-standard directory?
