SQL Data Source Configuration
MySQL
In order to use Direct DB Connection feature you should configure SQL data source first.
Select MySQL data source type and provide your database host address and port (3306 is default for MySQL). Fill
database name (usually, zabbix) and specify credentials.
Security notes
As you can see in User Permission note, Grafana doesn't restrict any queries to the database. So you should be careful
and create a special user with limited access to Zabbix database. Grafana-Zabbix plugin uses only SELECT queries to
history, history_uint, trends and trends_uint tables. So it's reasonable to grant only SELECT privileges to
these tables for grafana user. But if you want to use this MySQL data source for querying another data, you can
grant SELECT privileges to entire zabbix database.
Also, all queries are invoked by grafana-server, so you can restrict connection to only grafana host.
GRANT SELECT ON zabbix.* TO 'grafana'@'grafana-host' identified by 'password';
PostgreSQL
Select PostgreSQL data source type and provide your database host address and port (5432 is default). Fill
database name (usually, zabbix) and specify credentials.
Security notes
Make sure you use read-only user for Zabbix database.
InfluxDB
Select InfluxDB data source type and provide your InfluxDB instance host address and port (8086 is default). Fill
database name you configured in the effluence module config (usually, zabbix) and specify credentials.
