Hello All,
I have read some old discussions about using MongoDB as a data source. I mean, using Logstash to bring data from MongoDB and send it to Elasticsearch. Basically, this ([MongoDB Logstash Integration [Solved]](https://discuss.elastic.co/t/mongodb-logstash-integration-solved/122299)) is the start point.
However, I have some questions:
- Why there is no official logstash-input-mongodb plugin?
- If not, is there the development of this plugin in the roadmap?
- What would be the best way to bring a "slice" of data from MongoDB to Elasticsearch?
- Is there any logstash-input-mongodb current updated?
- Any way to run db.collection.aggregate against MongoDB and send the result to Elasticsearch?
Thank you in advance for any information,
Paulo

Hey @pmarques.
- As far as I know, there is no official logstash MongoDB Input plugin. But, there is an official [MongoDB output plugin](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-mongodb.html).
Concerning your question ,much of the power of open source comes from its community, so I think that it's okay that the community develop its own plugins, support them and embrace them. Elastic already developed more than 200 [plugins](https://github.com/logstash-plugins). I did found an official unmaintained mongodb [plugin](https://github.com/logstash-plugins/logstash-input-mongodb). But why developing 2 repositories for the same task?
- Logstash is based on pulling data. Therefore, I used the JDBC input plugin since it support scheduling for finding new rows/events by using **[rufus-scheduler](https://github.com/jmettraux/rufus-scheduler)**. You can also use logstash http puller inupt , which also support scheduling, and exposing a [REST service](https://docs.mongodb.com/ecosystem/tools/http-interfaces/) for your MongoDB.
Other alternative might be pushing data. [Here's](https://stackoverflow.com/questions/9691316/how-to-listen-for-changes-to-a-mongodb-collection) a collection of various mechanisms.
- Probably it depends whether the JDBC Input plugin and the MongoDB connector supports the aggregation functions. But i'm pretty sure that the REST service fully supports MongoDB features.

Hello @panda2004,
Thank you for your answer. I was thinking if there is a lack of NoSQL input plugins. I didn't find for Casandra either.
My solution for a while is a shell script wrapping a mongo shell + javascript (mongo -eval...), the problem here is that the full process takes 6.5 hours.
If it comes out any other idea, I will be pleased to share.
Cheers,
Paulo

If you just need one-time import of data, that's also a good input plugin:

Hello @panda2004,
Thank you for the suggestion. I have already tried [this](https://github.com/phutchins/logstash-input-mongodb)... This plugin is not well maintained and works well for bringing the whole collection. However, I need to bring a slice of it.
I will later publish my humble solution here.
Cheers,
Paulo

Hello all,
Sorry for the delay.
As I mentioned before the idea was having a baby step before pushing data to Elasticsearch. So, I wrapped a MongoDB query in a shell script which receives all parameter I need. The mongo query saves a CSV file which is handled by Logstash.
The query is something like:
mongo --quiet --host localhost --port 27017 DBNAME --eval variable=VALUE JAVASCRIPT \> output.csv
JAVASCRIPT is a script where happens the query and manipulates the data. The JAVASCRIPT just needs to print the data for saving the CSV.
Cheers,
Paulo
