MongoDB Latency Stats

MongoDB Latency Stats

In MongoDB, the latencyStats operation is used to retrieve latency statistics for operations on a collection. This method is essential for monitoring and optimizing the performance of MongoDB collections.

Syntax

db.collection.latencyStats(options)

The latencyStats method takes an optional options parameter to customize the retrieval of latency statistics.

Example MongoDB Latency Stats

Let's look at an example of how to use the latencyStats method in the programGuru collection in MongoDB:

1. Retrieve Latency Statistics

db.programGuru.latencyStats()

This command retrieves latency statistics for operations on the programGuru collection.

Full Example

Let's go through a complete example that includes switching to a database, creating a collection, inserting documents, and retrieving latency statistics.

Step 1: Switch to a Database

This step involves switching to a database named myDatabase.

use myDatabase

In this example, we switch to the myDatabase database.

Step 2: Create a Collection

This step involves creating a new collection named programGuru in the myDatabase database.

db.createCollection("programGuru")

Here, we create a collection named programGuru.

Step 3: Insert Documents into the Collection

This step involves inserting documents into the programGuru collection.

db.programGuru.insertMany([
    { name: "John Doe", age: 30, email: "john.doe@example.com" },
    { name: "Jane Smith", age: 25, email: "jane.smith@example.com" },
    { name: "Jim Brown", age: 35, email: "jim.brown@example.com" }
])

We insert multiple documents into the programGuru collection.

Step 4: Retrieve Latency Statistics

This step involves using the latencyStats method to retrieve latency statistics for operations on the programGuru collection.

db.programGuru.latencyStats()

We retrieve latency statistics for operations on the programGuru collection.
