The PRTG SNMP Synology System Health Sensor is designed to monitor the health and status of Synology network-attached storage (NAS) devices using the Simple Network Management Protocol (SNMP). Here are some key usages of this sensor:

1. Hardware Monitoring: The sensor provides comprehensive monitoring of hardware components such as CPU usage, memory utilization, disk status (including SMART attributes), RAID arrays, network interfaces, system temperatures, fan speeds, and power supply status. By continuously monitoring these parameters, administrators can detect hardware failures, performance bottlenecks, and potential issues that may impact the reliability and availability of Synology NAS devices.

2. Storage Health Monitoring: Storage devices are critical components of NAS systems, and their health and performance directly impact data availability and access. The sensor monitors disk status, including disk health, temperature, and SMART attributes, allowing administrators to detect early signs of disk failure or degradation. By monitoring RAID arrays, administrators can also ensure data redundancy and fault tolerance, minimizing the risk of data loss in the event of disk failures.

3. Network Performance Monitoring: Synology NAS devices serve as central repositories for data storage, file sharing, and network services in many environments. The sensor monitors network interfaces and bandwidth utilization, providing insights into network performance and identifying potential network congestion or bandwidth bottlenecks. This information helps administrators optimize network traffic and ensure smooth data transfer and access for users.

4. Temperature and Fan Speed Monitoring: Proper cooling is essential for maintaining optimal performance and reliability of NAS devices. The sensor monitors system temperatures and fan speeds, alerting administrators to temperature fluctuations or fan failures that may indicate inadequate cooling or potential hardware issues. By responding promptly to temperature and fan speed alerts, administrators can prevent overheating-related failures and prolong the lifespan of NAS hardware.

5. Power Supply Monitoring: Power supply failures can result in sudden system shutdowns and data loss. The sensor monitors power supply units (PSUs) and reports abnormalities such as voltage fluctuations, power supply failures, or insufficient power capacity. Administrators can receive alerts about power supply issues and take proactive measures to replace faulty PSUs or redistribute power loads to maintain system uptime and reliability.

6. Capacity Planning and Optimization: Historical data collected by the sensor can be used for capacity planning and optimization purposes. By analyzing trends in CPU and memory usage, disk space utilization, network bandwidth, and other performance metrics over time, administrators can identify potential resource constraints, plan hardware upgrades, optimize resource allocation, and improve overall system efficiency.

7. Alerting and Notification: The sensor provides customizable alerting and notification capabilities to inform administrators of hardware-related issues or events. Administrators can configure alerting thresholds based on resource utilization, temperature thresholds, disk health, or other criteria, allowing them to take proactive measures to address potential hardware failures, performance degradation, or capacity limitations.

Overall, the PRTG SNMP Synology System Health Sensor helps administrators monitor and manage Synology NAS devices effectively, ensuring the availability, performance, and reliability of network storage and services. By proactively monitoring hardware health, storage performance, network connectivity, and environmental factors, administrators can optimize Synology NAS device performance, mitigate hardware risks, and maintain a secure and resilient storage infrastructure.
