Hi all, I have trouble installing the logstah-filter-zeromq plugin on a clean logstash 5.1 install (tested with docker hub docker image logstash:5.1). Installation reports a version conflict. Full console output following below. The command used for installation is ``` logstash-plugin install logstash-filter-zeromq ``` Any advice is highly appreciated. Thanks in advance!

The issue is not docker specific but also happens on a clean Ubuntu 16.04 (using opejdk-8 jre). Any advice is highly appreciated! Alternatively: Is there any other method recommended to send logstash events to an external service for filtering? ---

Now also tried to build the plugin locally and get a more concise error message. It seems that the core-plugin-api and the zeromq mixin seem to require different versions of logstash-core. Is there any way to work aorund this? ``` ERROR: Installation Aborted, message: Bundler could not find compatible versions for gem "logstash-core": In snapshot (Gemfile.lock): logstash-core (= 5.1.1) In Gemfile: logstash-core-plugin-api (>= 0) java depends on logstash-core (= 5.1.1) java logstash-filter-zeromq (= 3.0.0) java depends on logstash-mixin-zeromq (>= 2.0.1) java depends on logstash-core (< 3.0.0, >= 2.0.0) java logstash-core (>= 0) java ``` ---

It looks like the zeromq plugin isn't compatible with Logstash 5. ---

Thanks for the answer! Is this really an incompatibility in terms of function? Because from what I can judge the necessary logstash-mixin-zeromq is uploaded to [rubygems.org](http://rubygems.org) only in version 2.0.2. When I download the logstash-mixin-zeromq locally it is built succesfully and generates a version 3.0.0 with a dependency on logstash core that is suitbale for 5.11, and therefore can be installed. I am currently struggling to get everything installed in my local logstash so can not (yet) make any assumptions if it will work properly ---

It could very well be that the maintainer of that plugin only needs to make a new release. ---

Final comment: I can confirm now that the problem is only caused by an outdated logstash-mixin-zeromq which is not "build against" the current logstash version. ---

@magnusbaeck Any chance you can prod the maintainer of zeromq plugins to take a look at this? -- Bud ---

Hi Bud, yes I managed to get it to work. Short informal description: Clone the logstash-mixin-zeromq "plugin" - build it locally and install. Then install the corresponding zeromq filter plugins (via the "standard" command that downloads the gem). I can look up more details (sorry don't have my notes at hand currently) if needed. ---

Hi Bud! Actually I did not fix it anything. Just building the zeromq-mixin against the current logstash was sufficient to resolve the version problem. That makes that whole issue so frustrating - basically everything is fine it is just the gem that is not uploaded in an up-to-date version to rubygems. Happy new year! ---
