Unable to start logstash using mongoDB config? -

-

i using logstash-1.5.2 mongodb 3.0.4. , trying start logstash below configuration not working.

input{     stdin{     } }  output {   mongodb {     database => "logdb"         collection => "plain"      uri => "mongodb://localhost:27017"    } }

i facing below errror :

./logstash -f conf/mongo.conf

the error reported is: uninitialized constant mongo::uriparser

please help.

the problem caused bug in latest version of logstash-output-mongodb. please see issue reported on github. can fixed changing few lines inside mongodb plugin. (please careful, hacky solution neither supports authentication nor remote servers.)

change lines of mongo.rb file mentioned here. (path should /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-mongodb-0.1.4/lib/logstash/outputs/mongodb.rb can find exact path in error message.)

replace:

    uriparsed=mongo::uriparser.new(@uri)     conn = uriparsed.connection({})     if uriparsed.auths.length > 0       uriparsed.auths.each |auth|         if !auth['db_name'].nil?           conn.add_auth(auth['db_name'], auth['username'], auth['password'], nil)         end        end       conn.apply_saved_authentication()     end     @db = conn.db(@database)

by:

    client = mongo::client.new([ '127.0.0.1:27017' ])     @db = client.use(@database)

and replace:

@db.collection(event.sprintf(@collection)).insert(document)

by:

@db.database.collection(event.sprintf(@collection)).insert_one(document)

i had issue myself in several logstash setups. changing lines did trick me everytime.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana
