burningalchemist/sql_exporter
SQL Exporter for Prometheus is a versatile, configuration-driven exporter designed to collect and expose metrics from various database management systems (DBMSs) for monitoring with Prometheus. It supports multiple databases out of the box, including MySQL, PostgreSQL, Microsoft SQL Server, Oracle Database, Clickhouse, Snowflake, and Vertica. The exporter can be extended to support any DBMS with a Go driver by rebuilding the binary with the appropriate driver included. The core functionality revolves around defining SQL queries grouped into logical collectors, which map the query results to Prometheus metrics. These collectors can be DBMS-specific or custom, allowing users to tailor metrics to their specific needs, such as monitoring data quality or system performance. The exporter operates synchronously with Prometheus scrapes, collecting metrics on each /metrics endpoint poll. To manage load, it supports configurable minimum collection intervals per collector, caching metrics when scrapes occur more frequently than the set interval. Deployment typically involves running the exporter alongside the database server, sharing the same failure domain. If the database is unreachable, the exporter returns an HTTP 500 error, signaling Prometheus to mark the target as down. Configuration is flexible, allowing global settings for connection management and scrape timing, as well as target-specific settings including the database connection string and the collectors to run. Collector definitions can be embedded in the main configuration or stored in separate files for reuse and sharing. The project provides examples and documentation to facilitate setup and customization. It also supports building minimal binaries with selected drivers to reduce size. Overall, SQL Exporter for Prometheus is a powerful tool for database monitoring, enabling detailed, customizable metric collection from a wide range of database systems, including Clickhouse, making it suitable for diverse monitoring environments.
