Hi all, i have an issue when i try to get data from mongodb to elasticsearch using logstash-input-mongodb. There is no document that get into elastic but when i stdout using rubydebug, logstash show me the documents in mongodb. After that i check the indices in elastic, they create the index but there is no document. 0 Doc in index that i created.

This my configuration file:

input {  
mongodb {  
uri =\> 'mongodb://\*\*\*:\*\*\*\*\*\*\*\*\*@localhost:27017/logs'  
placeholder\_db\_dir =\> 'E:\ELK\logstash-5.5.0\db\_dir'  
placeholder\_db\_name =\> 'logstash\_sqlite.db'  
collection =\> 'tx\_log'  
batch\_size =\> 5000  
generateId =\> 'true'  
parse\_method =\> "simple"  
}  
}  
output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> "tx\_logs"  
}  
stdout { codec =\> rubydebug }  
}

and this is some output from logstash console after they print the data on the console:  
s  
D, [2017-09-18T14:20:16.807000 #26876] DEBUG -- : MONGODB | localhost:27017 | logs.listCollections | STARTED | {"listCollections"=\>1, "cursor"=\>{}, "filter"=\>{:name=\>{"$not"=\>/system.|$/}}}  
D, [2017-09-18T14:20:16.812000 #26876] DEBUG -- : MONGODB | localhost:27017 | gosdev\_logs.listCollections | SUCCEEDED | 0.004s

and it looping forever.  
Thanks

so ladies and gentlemen, i already solved this problem. just add this filter:

filter {  
mutate {  
remove\_field =\> ["\_id"]  
}  
}

because, logstash generate mongo\_id and \_id with the same value
