# Zabbix DB Auditor
Zabbix DB Auditor is a collection Grafana dashboards designed to analyze Zabbix database size. This tool provides comprehensive visualizations and insights into your Zabbix database, helping you to optimize storage cost.

## Features
- **Easy-to-evaluate dashboard** - using modern type of visualization [Treemap]( https://grafana.com/grafana/plugins/marcusolsson-treemap-panel/).
- **Quick loading** - due to approximate analysis of the data planned for the storage.
- **Filters** - filters by host groups and hosts.
- **Accurate counting** - If necessary, it can count the items actually stored in tables.It also counts data from deleted hosts that has not yet been cleared.
## Prerequisites
Before you begin, ensure you have met the following requirements:
- **Grafana**: Ensure you have [Grafana](https://grafana.com/) 10+ installed and running.
- **Treemap Plugin**: for Grafana version **older than 11** you need to install a [Treemap Plugin](https://grafana.com/grafana/plugins/marcusolsson-treemap-panel/). Grafana 11 include this pluging.
- **Zabbix**: Of course, you need Zabbix. Versions 6.0 and 7.0+ are supported.
- **Database Access**: Currently the dashboard only supports MYSQL 8.0+. It is necessary to provide access to the Zabbix database and the ability to `GRANT` rights.
## Database access
The dashboard requires access to the Zabbix database.
in first, create user:
- make your own password
- make sure MySQL is not accessible from (container) network
```sql
CREATE_USER 'zabbix_db_auditor'@'%' IDENTIFIED BY 'pas_WoRD#!sw';
GRANT USAGE ON zabbix.* TO 'zabbix_db_auditor'@'%';
```
Then execute [grant script](sql/mysql/grant.sql) in zabbix database context.
The table names in the script are short, that is, this script depends on the launch context.
For zabbix version 6, you need execute another grant script [grant-zabbix-6.sql](sql/mysql/grant-zabbix-6.sql) (without `history_bin` table).
It is very important to create limited access to the database.
Often tables in Zabbix contain a lot of access data. But access to data in Grafana is different from what you would expect. You can read more about this in a separate [post in Grafana Blog](https://grafana.com/blog/2024/05/06/data-source-security-in-grafana-best-practices-and-what-to-avoid/) . Carefully granted access eliminates these problems.
## Dashboard Installation
Query sets differ for Zabbix versions and the selected database type.
Therefore, you need to upload to Grafana the corresponding file with the dashboard.
- [Zabbix 6 - MySQL](zabbix6/mysql/zabbix-db-auditor-zabbix6-mysql.json)
- [Zabbix 7 - MySQL](dashboards/mysql/zabbix-db-auditor-mysql.json)
- Zabbix 6 - Postgresql - **work in progress**
- Zabbix 7 - Postgresql - **work in progress**
The repository contains an example of setting up [datasource provisioning](provisioning-example/datasources/).
Of couse, dashboards can be provisioned too.
## Recomendations
It is recommended to set up some type of partitioning.
- For MySQL [Perl script partitioning](https://github.com/OpensourceICTSolutions/zabbix-mysql-partitioning-perl)
- For Postgresql [TimescaleDB setup](https://www.zabbix.com/documentation/current/en/manual/appendix/install/timescaledb)
The quick estimation panel works fast enough without these extensions.
## Caveats
- Zabbix items with flexible intervals not fully supported at the estimation dashboard, so it is suggested to calculate the actual items count. These dashboard elements are collapsed by default.
- Although the dashboard allows you to estimate which elements consume the most resources, it is almost impossible to calculate with byte accuracy. Service data, compression and fragmentation affect this.
- Even though this is a Zabbix dashboard, it does not use access via API and a special Zabbix Grafana plugin. You need direct network access to the Zabbix database.
