Ubuntu Oracle数据库性能监控工具推荐

Here are the recommended tools for monitoring Oracle database performance on Ubuntu:

1. Oracle Enterprise Manager (OEM)

OEM is Oracle’s comprehensive, native monitoring solution, offering real-time performance metrics, historical trend analysis, and automated alerting. It integrates with all Oracle Database components, providing a centralized dashboard for managing performance, space usage, backups, and security. Key features include SQL Tuning Advisor, Real-Time SQL Monitoring, and Workload Replay. While it’s user-friendly and feature-rich, OEM can be expensive for small deployments and requires significant setup/configuration.

2. Prometheus + Grafana + Oracle Exporter

This open-source stack is ideal for dynamic, cloud-native environments. Prometheus collects time-series metrics from Oracle via Oracle Exporter (a Go-based tool that exposes Oracle performance data in Prometheus format). Grafana visualizes these metrics with customizable dashboards (e.g., CPU usage, session counts, query performance). The stack is highly scalable, supports alerting via Alertmanager, and integrates with other infrastructure tools. It’s cost-effective but requires manual setup of each component.

3. Zabbix

Zabbix is an enterprise-grade, open-source monitoring platform that supports Oracle Database through agents or custom scripts. It monitors key metrics like CPU, memory, disk I/O, and Oracle-specific stats (e.g., active sessions, SQL execution time). Zabbix offers flexible alerting (email, SMS, Slack), auto-discovery, and distributed monitoring. It’s suitable for large-scale deployments but has a steeper learning curve than simpler tools.

4. MyOra

MyOra is a free, lightweight tool designed exclusively for Oracle performance monitoring. It provides real-time insights into sessions, SQL execution, locks, and system resources without requiring Oracle client installation. Key features include a simple GUI, customizable alerts, and basic performance tuning recommendations. It’s easy to use and suitable for small to medium databases but lacks advanced features like automated root cause analysis.

5. oratop

oratop is a command-line tool (similar to Linux’s top) that provides near-real-time monitoring of Oracle Database activity. It displays metrics like active sessions, SQL execution rates, wait events, and resource usage (CPU, memory) in an interactive terminal interface. Ideal for quick checks or scripting, oratop is lightweight and efficient but not as feature-rich as GUI-based tools.

6. SQL Developer

SQL Developer is a free, GUI-based tool from Oracle that combines database development and monitoring. It offers real-time performance dashboards (e.g., SQL Execution, Memory Usage), session monitoring, and SQL tracing. Key features include customizable reports, PL/SQL debugging, and integration with version control. While not as specialized as OEM, it’s a versatile tool for developers and DBAs who already use it for database management.

7. OSWatcher

OSWatcher is Oracle’s free, lightweight system monitoring tool that collects OS-level metrics (CPU, memory, disk I/O, network) alongside Oracle performance data. It helps correlate database performance with underlying system issues (e.g., disk bottlenecks). OSWatcher is easy to deploy (no additional licensing) and generates archived logs for historical analysis, making it suitable for small-scale or troubleshooting scenarios.

Each tool has its strengths—choose based on your environment (e.g., open-source vs. commercial), scale (small vs. large), and required features (real-time monitoring vs. historical analysis). For example, OEM is best for comprehensive management, while Prometheus+Grafana suits cloud-native setups, and MyOra/Zabbix are great for cost-effective monitoring.
