  • mongolab/dex

    Dex is a MongoDB performance tuning tool that analyzes queries and suggests indexes based on simple heuristics. It compares queries to available indexes in the queried collection(s) and generates recommendations. Dex supports log files and the system.profile collection for analysis. It recommends complete indexes and ignores partial indexes, favoring better options. You can filter analysis by specific collections, databases, or query execution time. Dex can run in watch mode for real-time information. It provides query reports with index recommendations and helpful shell commands. Dex is recommended for MongoDB version 2.2.0 or later.
