Perform Advanced Query Analysis The following methods are suited for deeper investigation of problematic queries, and can provide fine-grained performance insights: Method Availability Description View plan cache statistics Atlas clusters and self-hosted deployments ...
Opening the query code in the Collection Tab, Aggregation Editor, or IntelliShell does not run the slow query and impact the performance any further on your MongoDB database. Explain plan Explain plan is a visual representation of the performance of a MongoDB find query. It shows the query p...

You can use partitions to improve Data Federation performance by mapping them to partition attributes in yourconfiguration. By mapping yourpartition attributes(the parts of yourS3prefix that looks like a folder) to a query attribute, Atlas Data Federation can selectively open the files that contain ...
To facilitate analysis of the MongoDB server behavior by MongoDB Inc. engineers, mongod and mongos processes include a Full Time Diagnostic Data Collection (FTDC) mechanism. FTDC data files are compressed, are not human-readable, and inherit the same file access permissions as the MongoDB data...

Automated profiling analysis is designed to provide a centralized view of latency, throughput, errors, and more across your MongoDB ecosystem in real time. Using Database Observability, MongoDB performance issues can typically be resolved in minutes instead of spending hours analyzing query logs or ...
