MongoDB

Connect RootCause to MongoDB to import collections as tables. Nested documents are flattened into columns.

---

Prerequisites

• A MongoDB connection string (standard or SRV)

• A user with read access to the collections you want

• Network access, including IP allowlisting for Atlas clusters

---

Setting up the connection

1. In the Import Manager, click the MongoDB card

2. Enter the connection string:

Field	Description	Example
Connection String	MongoDB connection URI, including credentials	mongodb+srv://user:[email protected]/db

1. Click Test connection to verify, then Save & continue

---

Importing data

1. Browse to the Database and Collection, or type their names.

2. Optionally set a Query Filter, a MongoDB query document such as { "status": "active" }. Leave empty to import all documents.

3. Under Advanced Options, tune how documents become rows:

   • Flatten Depth (1 to 5): how many levels of nested objects are flattened into separate columns.

   • Stringify Arrays: convert arrays to JSON strings for tabular compatibility.

Browse to a collection, optionally filter with a MongoDB query document.

Import modes

Full Import, Full Import + Live, Recent Rows and Time Period. Rolling windows are resolved by MongoDB itself. Query Directly is not available for MongoDB. See Connectors.

Troubleshooting

Server selection timeout

• For Atlas, add RootCause's address to the IP access list; check SRV DNS resolution

Authentication failed

• Confirm the auth database in the URI (often ?authSource=admin)

Columns missing

• Raise the flatten depth, or check that the fields exist in the filtered documents
