Preface: Debug logs may contain user IDs and passwords to provide diagnostic information for failed login attempts, authentication failures, or to trace user activity within an application, but this is a significant security risk and should be avoided. Security best practices dictate that sensitive information like passwords should never be logged in cleartext. Instead, logging should only include non-sensitive user identifiers to help with troubleshooting without exposing credentials

Background: NVIDIA’s NVDebug tool is part of the broader Nsight Systems tool suite and relies on the NVIDIA Data Center GPU Manager (DCGM) library, specifically utilizing it for data collection and diagnostics to assist in troubleshooting and monitoring NVIDIA GPUs.

• NVDebug is a tool for debugging and profiling NVIDIA GPUs, particularly in data center environments.
• DCGM is a library for managing and monitoring NVIDIA GPUs in clusters and data centers.

NVDebug uses the DCGM library to gather essential diagnostic data, logs, and health information from the GPUs, enabling detailed analysis of the system’s state and performance.
