You don't have any reference to the mongodb plugin
Your input need to be like this :
```auto
input {
mongodb {
uri => 'mongodb://userhere:passwordhere@1234.234.123.12:8081'
placeholder_db_dir => '/opt/logstash-mongodb/'
placeholder_db_name => 'logstash.db'
collection => 'mtg_stuff'
batch_size => 5000
}
}
```

If you don't have data in elasticsearch, i think it's because logstash fail to acces to the values in mongodb. The error can't come from the communication between logstash and elasticsearch because you don't have any error in your logs.
I never use mongodg before so i'm can't help about his configuration.

I would start Logstash using `--debug` to get more details on what's going on.
Also this plugin is a 3rd party and if you suspect the input plugin is having issues you can ask questions on their [github](https://github.com/phutchins/logstash-input-mongodb/issues).
