MariaDB

Description

Monitors performance and operational metrics for a MariaDB database.

database linux windows

Target

Typical platform: MariaDB

Operating systems: Microsoft Windows, Linux

Prerequisites

Leverages: MariaDB Server 11.8 or higher

Technology and protocols: SQL/JDBC

Examples

CLI

metricshub HOSTNAME -t win -c +MariaDB --jdbc -u USER --jdbc-url URL

metricshub.yaml

resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: win
        connectors: [ +MariaDB ] # Optional, to load only this connector
        protocols:
          jdbc:
            port: <PORT>
            database: <DB_NAME>
            type: <type>
            url: <URL>
            username: <USERNAME> # Change with actual credentials
            password: <PASSWORD> # Encrypted using metricshub-encrypt

Connector Activation Criteria

The MariaDB connector will be automatically activated, and its status will be reported as OK if all the below criteria are met:

• The SQL query below succeeds:
  • Query: SELECT @@version LIKE '%MariaDB%' AS is_mariadb;
  • Result contains: 1 (regex)
