    Fingerprint¶

    A normalized statement digest—a query string with values removed that acts as a template or typical example for a query.

    IAM¶

    Identity and Access Management (for Amazon AWS).

    MM¶

    Metrics Monitor.

    NUMA¶

    Non-Uniform Memory Access.

    PEM¶

    Privacy Enhanced Mail.

    QPS¶

    Queries Per Second. A measure of the rate of queries being monitored.

    Query Analytics¶

    Component of PMM Server that enables you to analyze MySQL query performance over periods of time.

    Advisors¶

    Automated checks that you can run against connected databases to identify any potential security threats, configuration problems, performance concerns, policy non-compliance issues etc.

    Technical Preview¶

    Releases intended for public preview and feedback, but with no support or service level agreement (SLA). Should not be used on production or business-critical systems. May contain breaking changes to UI, API, CLI. (Read more.)
