    • Discovery can identify an instance of MySQL that is running on UNIX or Windows operating systems.

    Requirements

    Discovery searches for the MySQL configuration file location from the following areas:
    • UNIX: Discovery searches for the MySQL configuration file location from the mysqld process, or port 3306.
    • Windows: Discovery searches for the MySQL configuration file location from the mysqld.exe process, or port 3306.
    For each process, the following process parameters are explored in the following order:

    --defaults-extra-file

    --defaults-file

    If the MYSQL configuration file location is not found from that search, then the following occurs:
    • UNIX: The configuration file location defaults to /etc/my.cnf.
    • Windows: No default configuration file location exists, and the probe to read the configuration file location is skipped.
    Remarque :
    For information on Probe to Pattern migration see the knowledge article KB0694477.

    Credentials

    Configure these credentials:

    For a list of privileged commands that you need for Discovery and Service Mapping, see Service Mapping commands requiring a privileged user. This list includes commands that require elevated rights to discover and map Unix-based hosts in your organization.

    Classifiers, patterns, and probes

    Discovery uses these classifiers, probes, and patterns for MySQL discovery:
    Classifier Trigger probes Pattern
    MySQL Server
    • Horizontal Pattern: launches patterns
    • Windows - MySQL Configuration*
    • Windows - MySQL Version*
    • MySQL - Configuration*
    • MySQL - Version*
    		 My SQL server On Windows and Linux Pattern

    *For new instances, these probes are inactive on the classifier. Discovery uses patterns for discovery.

    To use patterns, verify that the correct pattern is specified in the horizontal pattern probe on the classifier. See Add the Horizontal Pattern probe to a classifier for instructions.

    Data collected

    Discovery populates these fields in the MySQL Instance [cmdb_ci_db_mysql_instance] table:
    Label Field name Source
    MySQL configuration myconf my.cnf
    TCP port(s) tcp_port running_process
    Version version mysqld
