As an experienced sysadmin, you know that your [databases are one of the most important pillars](https://www.paessler.com/database-monitoring) of your IT infrastructure. Whether it’s financial and employee data in the ERP system or sensitive customer information in your CRM, virtually all structured data is stored in databases. If your database fails or gets breached, you could face major financial hits, disrupted operations, a tarnished reputation, and even legal troubles.

In other words, your database directly impacts the performance and efficiency of your systems and applications. You should be using database monitoring tools to track key metrics and address potential performance problems before they escalate.

[![why you should monitor your databases](https://blog.paessler.com/hubfs/2018/blog/header/considerations-when-choosing-database-management-system.png)](https://blog.paessler.com/why-you-should-monitor-your-databases)

## What database metrics you should monitor

It is therefore obvious that you should be seamlessly aware of the status of your databases. So, what exactly should you be keeping an eye on? Let’s break it down.

### Performance metrics

To [optimize database performance](https://www.paessler.com/database-performance), it’s crucial to monitor key performance metrics such as response times, resource usage (including CPU, memory, and disk I/O), query execution times, and throughput. When query response times slow down, it can significantly affect your applications’ performance, frustrate users, and lead to potential business losses. Tracking execution plans and detecting bottlenecks like slow queries or high resource consumption helps you troubleshoot database issues effectively.

### Security metrics

Next, there is security. This involves monitoring for unusual access patterns, unauthorized access attempts, or any changes to your database configurations. Effective security monitoring is vital for protecting sensitive data and identifying breaches early. Anomalies in SQL queries or changes in database schema can signal potential threats. Notifications and thresholds for critical events are essential to maintaining a secure environment.

### Compliance metrics

Depending on your industry, you might need to follow regulations like GDPR or HIPAA. Comprehensive database monitoring ensures compliance by tracking access logs, maintaining detailed audit trails, and enforcing data retention policies. Monitoring compliance-related metrics, such as aggregate query execution results and user access history, helps validate that your database systems adhere to regulatory requirements.

## What can you monitor out of the box with PRTG Network Monitor?

If you decide to use [Paessler PRTG Network Monitor](https://www.paessler.com/prtg) to monitor your databases, you have access to a variety of sensors that focus on specific aspects of database performance, security, and availability. These sensors support multiple database systems, including Microsoft SQL Server, MySQL, Oracle, and PostgreSQL. Here’s an overview:

### Microsoft SQL v2 Sensor

This sensor allows you to monitor database performance metrics like response times, number of active connections, or the success/failure of critical SQL statements. It’s ideal for tracking query performance and detecting performance issues in SQL Server.

### MySQL v2 Sensor

With this sensor, you can monitor metrics such as query execution times, open connections, and error messages. Real-time insights into MySQL performance help you identify bottlenecks and optimize resource utilization.

### Oracle SQL v2 Sensor

This sensor tracks response times for critical queries, the number of active sessions, and error counts. It supports performance tuning and resource optimization in Oracle database systems.

### PostgreSQL Sensor

Use this sensor to monitor latency, status of database objects, and slow queries. It ensures that PostgreSQL databases maintain high availability and user experience.

### Ado SQL v2 Sensor

This flexible sensor supports monitoring multiple database platforms. You can track custom database monitoring metrics tailored to your needs, correlating performance data across systems.

### SNMP Custom Sensor

If your database system supports SNMP, this sensor lets you monitor specific OIDs for customized insights. It’s ideal for integrating database monitoring into your existing observability dashboards.

### File Content Sensor

This sensor scans database logs for critical events, errors, or security issues. It helps detect anomalies, enabling timely troubleshooting and performance tuning.

With these sensors, PRTG Network Monitor provides comprehensive monitoring tools for database performance, user experience, and regulatory compliance. Dashboards with visualizations of key metrics, such as response time and resource consumption, help you spot performance problems before they cause downtime.
