As of my last update, there isn't a specific PRTG SNMP IBM TS7930 System Health Sensor. However, you can typically monitor IBM tape libraries, such as the TS7930 series, with SNMP traps or by using PRTG's generic SNMP sensors to monitor basic system health parameters. Here are some potential usages:

1. Device Status Monitoring: Utilize SNMP to monitor the overall status of the IBM TS7930 tape library, including its operational status, connectivity, and availability.

2. Component Health: Monitor critical components within the tape library, such as drives, robotic arms, power supplies, and cooling systems, to ensure they are functioning correctly.

3. Error Detection and Alerts: Configure SNMP traps or SNMP-based sensors to detect errors or warnings reported by the tape library, such as drive errors, tape path obstructions, or temperature warnings. Set up alerts to notify administrators when such events occur.

4. Capacity Monitoring: Track the usage and availability of tape cartridges (media) within the library to ensure that there are sufficient tapes for backup or archival purposes. Set thresholds to alert when tape capacity reaches certain levels.

5. Performance Metrics: Monitor performance metrics related to tape drive utilization, data transfer rates, and robotic arm movements to identify potential performance bottlenecks or issues affecting backup or restore operations.

6. Security Monitoring: Monitor access logs or security-related events reported by the tape library to detect unauthorized access attempts or security breaches.

While there may not be a dedicated sensor for the IBM TS7930 series, you can leverage PRTG's flexibility with SNMP monitoring to create custom sensors or use generic SNMP sensors to monitor the health and performance of the tape library. Additionally, check for any updates or new sensor releases from PRTG that may include support for IBM TS7930 or similar tape libraries.
