Command Word Analysis

Last updated: 2022-06-24 16:34:17

    Feature Description

    The command word analysis feature performs statistical analysis on the number and latency of database access commands. Latency analysis helps you quickly find the most frequently used command, and command word analysis helps you further identify when the command is most frequently executed as well as its execution latency, which facilitates troubleshooting and performance optimization.
