How can you monitor the health and performance of a MongoDB deployment?

The key to monitoring MongoDB's health and performance lies in mastering core metrics and using tools reasonably. First, you need to pay attention to system resources, including CPU usage, memory usage, disk I/O and network traffic, and use top, htop, iostat or Prometheus Grafana to monitor; secondly, use MongoDB's own commands such as db.currentOp(), db.serverStatus(), db.collection.stats() and rs.status() to quickly understand the database status; then configure automated monitoring tools such as MongoDBAtlas, Prometheus MongoDBExporter,

How to Use MongoDB with Python for Data Analysis

MongoDB and Python can efficiently analyze unstructured data, and PyMongo and pandas libraries need to be installed; 2. Connect the local or Atlas database through PyMongo to access the specified database and collection; 3. Use find() to query the data and convert it to pandasDataFrame to clean the inconsistent fields; 4. Use pandas for grouping, statistics and other analysis, and the results can be stored back to MongoDB or exported to CSV; 5. It is recommended to manage memory for large data sets and index them to improve query performance.

How to Build a Recommendation Engine with MongoDB

Use MongoDB's flexible mode, indexing, and aggregation pipeline to build a lightweight recommendation engine. 2. Design user, item and interactive data models to support recommendations based on content or collaborative filtering. 3. Use the aggregation pipeline to analyze behavior, such as generating recommendations through co-occurrence calculations. 4. Create indexes for commonly used query fields to improve performance. 5. Combining application logic, implement user similarity calculation, cache recommended results, and trigger updates with change flow. 6. The user recommendation list can be pre-calculated and stored to speed up retrieval. MongoDB is suitable for implementing a simple recommendation system that is driven by real-time behavior.
