I am trying to parse JSON (from MongoDB) to Kibana through Logstash. I keep getting all the data in a "log\_entry" field. This field does not exist in my data but rather is being created by Logstash. In my CONF file, I have my filter empty. I have tried adding JSON with source as a specific field but that does not work either. Any ideas? ![43%20PM](https://us1.discourse-cdn.com/elastic/original/3X/a/0/a0310e47439f2f468c525ffa3f52cd93621dcc66.jpeg) ---

The `log_entry` field is not valid JSON, which is why the json filter fails. ---

my data structure has NO field with the name "log\_entry".. Logstash is creating this. I want to import the individual fields but unable to do so ---

Here is the config file ![21%20PM](https://us1.discourse-cdn.com/elastic/original/3X/c/c/cc5e20c9c21d810d934a6cd43971da6a98168239.png) ---

I suspect that structure is created by the mongodb input plugin, which I have personally never used. I am not sure how commonly used it is, so you may want to reach out to the creator as well. ---
