Mamonsu
An active monitoring agent for PostgreSQL that collects instance and system metrics and integrates with Zabbix.
What is Mamonsu?
mamonsu is an active monitoring agent that collects PostgreSQL database and operating system metrics and sends them to a Zabbix server for visualization. It solves the problem of comprehensive PostgreSQL performance monitoring by providing out-of-the-box metrics, triggers, and dashboards while minimizing resource usage on the database server.
Database administrators and DevOps engineers who manage PostgreSQL instances and use Zabbix for infrastructure monitoring.
Developers choose mamonsu for its deep PostgreSQL-specific metrics, seamless Zabbix integration, and low performance overhead due to its single-connection design and efficient plugin architecture.
Overview
mamonsu is a monitoring agent specifically designed for PostgreSQL, providing comprehensive collection of database and operating system metrics. It integrates seamlessly with Zabbix, offering a robust solution for database administrators to monitor PostgreSQL health and performance. The agent is built with a plugin architecture, allowing for extensibility and customization to meet specific monitoring needs.
Key Features
- Active Agent — Sends collected metrics directly to the Zabbix server, minimizing performance impact on the monitored PostgreSQL instance.
- Comprehensive Metrics — Collects approximately 90 PostgreSQL-specific metrics (e.g., connections, locks, WAL, checkpoints) and 40 system metrics (e.g., CPU, memory, load average).
- Zabbix Integration — Generates and uploads Zabbix templates complete with pre-configured screens, dashboards, triggers, and graphs for immediate visualization.
- Plugin Architecture — Written in Python 3 with a modular plugin system, enabling users to create custom plugins for additional metrics.
- Cross-Platform Support — Runs on Linux, FreeBSD, and Windows, supporting PostgreSQL versions 12 through 18 and Zabbix server versions 4.0.44 to 6.4.13.
- Command-Line Tools — Provides utilities for bootstraping, tuning PostgreSQL settings, generating system reports, and managing Zabbix hosts and templates via CLI.
Philosophy
mamonsu prioritizes minimal performance overhead by using a single database connection for metric collection and emphasizes ease of integration with existing Zabbix monitoring ecosystems.
