PostgreSQL with Timescale is the ultimate storage partner for Grafana. We discussed how to update Grafana environment variables to use the PostgreSQL database in our recent video. When Grafana users make any changes (for instance, adding data sources and visualizations), these changes go into a separate entity, namely, configuration storage. On that setup, the Grafana UI and the configuration storage (which is NOT the same as application data storage) are separated and dwell in two segregated containers and/or hosts. In the Next level setup, Grafana UI connects to the external PostgreSQL or MySQL database. ![]() The next level setup is the lowest level you must be on for any commercial and industrial applications. An inquisitive beginner-to-intermediate developer or analyst can tackle the task with ease. The skill level required for this setup is relatively minimal. The default setup suits beginners well since it eliminates the maintenance needs allowing them to start exploring Grafana instantly, literally minutes after they learned about Grafana's existence. The code of SQLite is open for anyone to use for any purpose. The database is so tiny and fast that some people do not even realize it exists side by side with their favorite applications on the phone or computer. The database is meant to be coupled with an application, ensuring high reliability and efficiency. SQLite is designed explicitly for small applications and is widely employed in myriads of applications across the globe. Users cannot introduce changes to the provisioned dashboard and data sources unless it's allowed in the configuration. This mechanism is a simplified way to create applications with embedded/preset data sources, plugins, and dashboards. ![]() Provisioning is a mechanism to push dashboards and data source configuration using JSON files into Grafana UI. In the default setup, Grafana is bundled with the SQLite database. Grafana configuration is stored in a database. Grafana configuration is a set of parameters describing # mysql: go-sql-driver/mysql dsn config string, e.g.In the default setup, Grafana is bundled with the SQLite database. # file: session dir path, is relative to grafana data_path # Either "memory", "file", "redis", "mysql", "postgres", default is "file" # For "sqlite3" only, path relative to data_path setting # For "postgres" only, either "disable", "require" or "verify-full" # Either "mysql", "postgres" or "sqlite3", it's your choice You can turn off this feature to get a quicker startup with -AĮdit the grafana.ini configuration file (in Ambari, edit the Advanced ams-grafana-ini section in the Ambari Metrics Config tab) - see snippet from the config file below Reading table information for completion of table and column names Mysql> GRANT ALL PRIVILEGES ON `grafana`.* to with grant option Query OK, 0 rows affected (0.00 sec) Mysql> GRANT USAGE ON `grafana`.* to identified by 'grafanamysqlpasswd' On MySQL server (be sure to change the password): mysql> create database grafana ![]() The session table however does not get created and the grafana docs say to create it for MySQL and postgres - so create the session table as per the grafana docs Starting Grafana creates the grafana tables.Edit the grafana.ini configuration file to enable use of MySQL (Edit the Advanced ams-grafana-ini section in the Ambari Metrics Config tab in Ambari).Create a MySQL user called grafana, assign and flush privileges. ![]() Assume you have a MySQL database server running on.
