Plugin failed with logstash 1.5.0.rc2 about logstash-output-mongodb

[mellonbrook]

I am having this issue as well. I am working on a solution. I have a lead though. So the issue is in this file: (https://github.com/logstash-plugins/logstash-output-mongodb/blob/master/lib/logstash/outputs/mongodb.rb) with the call to Mongo::URIParser. The mongo gem being imported does not have a URIParser class. The following is the uri.rb file from the mongo gem being imported https://github.com/mongodb/mongo-ruby-driver/blob/master/lib/mongo/uri.rb. Notice it does not have a URIParser class. I hope this helps somewhat.

So I fixed the issue. Heres a link to my repo with the fix: master...mellonbrook:fix-update-mongoruby

I removed the authentication code because I dont need it and because I dont have time right now to fix it.

Let me know if you have any questions.

I'm facing this issue too... the last version seems broken to me

[cabrinoob]

Same problem here ... (I'am using logstash 1.5.0 and mongodb 3.0.3)

[mellonbrook]

I created a fork of the plugin that works for me. Heres the link: https://github.com/mellonbrook/logstash-output-mongodb/tree/fix-update-mongoruby

The fork doesn't use authentication and the URI is hardcoded in the plugin to '129.0.0.1:27017'

Heres the diff: master...mellonbrook:fix-update-mongoruby

I am facing a problem with logstash 1.4.3 (I am using mongoDb 3.0.3).I am getting thi error message:

Using milestone 2 output plugin 'mongodb'. This plugin should be stable, but if you see strange behavior, please let us know! For more information on plugin milestones, see http://logstash.net/docs/1.4.3/plugin-milestones {:level=>:warn}

is something wrong with logstash or what?Thank you

The problem occurs because the logstash-output-mongodb plugin requires the mongodb gem without requiring a specific version. When the mongo gem was updated to version 2.0.0, the Mongo:URIParser class was replaced with the URI class.

I supplied a fix in a fork by adding a specific version requirement for the mongo gem.

Thank you for you're answer 👍 but it still doesn't work for me.I have this error message :

The error reported is:
uninitialized constant Mongo::URIParser

(I am using the last version of logstash 1.5.1)

[lucashenning]

I had the same problem with logstash 1.5.1

The error reported is: 
  uninitialized constant Mongo::URIParser
org/jruby/RubyModule.java:2733:in `const_missing'
/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-mongodb-0.1.4/lib/logstash/outputs/mongodb.rb:37:in `register'

I changed a few lines as suggested by @mellonbrook ( master...mellonbrook:fix-update-mongoruby )

It works now 👍 Thank you

[svezzoli]

I have the same problem with logstash 1.5.2.
But do it will be possible to fix this problem definitively on master branch?
Thanks.

I applied the changes suggested by @mellonbrook but this is only a work around and it is not right for my use case.
Our product uses the authentication to access to mongodb, and so it is not a valid solution to remove the authentication and to make use of an hardcoded value for URI ('127.0.0.1:27017'), the mongodb access via authentication (any mechanism) should be guaranteed at least.

In this situation this plugin is unusable!
Why is there no more maintenance on logstash-output.mongodb plugin?

[purbon]

Good morning @svezzoli , the mongodb output is a community contributed one, this days with tons of plugins under the umbrella of the logstash-plugins organization and the size of our internal core team, we get the places we can, but certainly not to everywhere.

We'll be more than happy to review and merge as much patches as possible here, with all your help, awesome community, we can make this work. Things like raising importance of fixes, reviewing code, proposing PR, etc ... every small detail is highly welcome.

Sayed that, please feel free to point us how can we fix the issues you guys are having?

/cheers

[purbon]

This issue should be gone with the new release of the plugin (https://rubygems.org/gems/logstash-output-mongodb), the URI one, did not work on the authentication issue for now.

@svezzoli @mellonbrook @lucashenning as I said this is a community maintained plugin, feel free to contribute ideas and code back! all PR are welcome you guys can step in every time you want, for example doing reviews, raising issues, etc.

/cheers

I'm going to close this one in benefit of having only one issue for the authentication problem. The problem stated here is the upgrade issue, that is fix for now.
