The MySQL Exporter in 01Cloud is a tool that facilitates the extraction of metrics from MySQL databases, making it possible to monitor their performance and health using Prometheus. This exporter collects a wide range of MySQL metrics, such as query performance, connection stats, buffer pool usage, and more, and exposes them in a Prometheus-compatible format.
Here are some common variables or configurations you might need when using Mysql Exporter:
- HOST: The hostname or IP address of the MySQL server.
- PORT: The port number on which MySQL is running (usually 3306).
- USER: The username to connect to the MySQL database.
- PASS: The password associated with the specified user.
- DB: The name of the database from which you want to export data.
Features of MySQL Exporter:
1. Comprehensive Metric Collection:
- Gathers extensive metrics related to MySQL performance, including query execution times, connection statistics, buffer pool usage, and more.
- Provides a detailed view of MySQL database performance and health, enabling effective monitoring and troubleshooting.
2. Ease of Integration:
- Easily integrates with Prometheus and the 01Cloud monitoring stack.
- Simplifies the setup process, allowing users to quickly start monitoring their MySQL databases.
3. Customizable Metrics:
- Allows configuration of which metrics to collect and expose.
- Offers flexibility to focus on the most relevant metrics for your specific use case.
4. Security:
- Supports secure connections and authentication methods.
- Ensures that database connections and metric collections are secure, protecting sensitive data.
