Prune plugin cannot be found by systems after being installed


(Jan Claeyssens) #1

Hi,

maybe I'm looking at this all wrong, but I can't find what I"m doing wrong here.
I installed the prune filter, with this command:
bin/logstash-plugin install logstash-filter-prune
which was successful and I can list the plugin:
bin/logstash-plugin list --verbose prune logstash-filter-prune (3.0.3)
However, I still get following error in the logs:

[2018-06-04T16:09:57,478][ERROR][logstash.plugins.registry] Tried to load a plugin's code, but failed. {:exception=>#<LoadError: no such file to load -- logstash/filters/prune>, :path=>"logstash/filters/prune", :type=>"filter", :name=>"prune"}

Automatic reload is enabled, so it should pick it up.
Any idea what I'm doing wrong??

Cheers

Jan

Update

Because I can no longer reply to this thread, this can be solved by simply restarting the logstash service, even if automatic reload of config is enabled.
Would be handy if this is mentioned somewhere in the docs...
