MongoDB Data Stream Parameters

The MongoDB plugin provides a configurable data stream to easily query and visualize data from any MongoDB-compatible database.

Each configurable data stream exposes a set of parameters that lets you filter the data you retrieve. The following information describes the available configurable data streams and their parameters in detail.

Query

Runs a query against a MongoDB collection. Query operation sets the shape of the result, from a set of matching documents to a single count or an aggregation pipeline.
