A DGX H100 system in a cluster is showing performance issues when running jobs. Which command should be run to generate system logs related to the health report?

The nvsm dump health command is the correct utility for collecting a comprehensive set of system health and diagnostic information on an NVIDIA DGX system. When executed, it gathers logs, hardware status, software configuration, and performance data, packaging it into a single compressed archive file (.tar.gz). This file is essential for support teams and system administrators to perform an in-depth, offline analysis of system issues, such as performance degradation, without needing direct access to the live system.

A. nvsm show logs --save: This command is used to display specific system logs (e.g., event logs) to the console. While the output can be redirected, it does not generate the comprehensive diagnostic bundle that nvsm dump health creates.

B. nvsm get logs: This is not a valid command or syntax within the NVIDIA System Management (NVSM) command-line interface. The standard verbs are show, dump, run, etc.

D. nvsm health --dump-log: This is not a valid NVSM command. The command to actively run a health check is nvsm run health, which provides a summary of the system's status, not a full log dump.

1. NVIDIA DGX OS User Guide (Version 6.1.0):

Section 5.5, "Dumping System Information": This section explicitly details the nvsm dump command. It states, "nvsm dump health: Collects health information and saves it to a file." This confirms that this is the designated command for creating a health report archive for troubleshooting.

Section 5.9, "Running System Checks": This section describes nvsm run health, clarifying its purpose is to execute a health check and display a summary, which is different from dumping detailed logs.

Section 5.10, "Showing System Information": This section details the nvsm show logs command, confirming its function is to display logs rather than create a diagnostic package.
