This section provides instructions for IT administrators on collecting NVIDIA Run:ai logs for support, including prerequisites, CLI commands, and log file retrieval. It also covers enabling verbose logging for Prometheus and the NVIDIA Run:ai Scheduler.

Collect Logs to Send to Support

To collect NVIDIA Run:ai logs, follow these steps:

Step-by-step Instructions
  1. Run the Command from your local machine or a Bastion Host (secure server). Open a terminal on your local machine (or any machine that has network access to the Kubernetes cluster) where the NVIDIA Run:ai Administrator CLI is installed.

  2. Collect the Logs. Execute the following command to collect the logs:

This command gathers all relevant NVIDIA Run:ai logs from the system and generate a compressed file.

  1. Locate the Generated File. After running the command, note the location of the generated compressed log file. You can retrieve and send this file to NVIDIA Run:ai Support for further troubleshooting.

Note

The tar file packages the logs of NVIDIA Run:ai components only. It does not include logs of researcher containers that may contain private information.

Increase log verbosity to capture more detailed information, providing deeper insights into system behavior and make it easier to identify and resolve issues.

Before you begin, ensure you have the following:

Adding verbosity to Prometheus

To increase the logging verbosity for Prometheus, follow these steps:

  1. Edit the RunaiConfig to adjust Prometheus log levels. Copy the following command to your terminal:

    kubectl edit runaiconfig runai -n runai
  2. In the configuration file that opens, add or modify the following section to set the log level to debug:

    spec:
      prometheus:
        spec:
          logLevel: debug
  3. Save the changes. To view the Prometheus logs with the new verbosity level, run:

    kubectl logs -n runai prometheus-runai-0 

    This command streams the last 100 lines of logs from Prometheus, providing detailed information useful for debu

Adding verbosity to the Scheduler

To enable extended logging for the NVIDIA Run:ai scheduler:

  1. Edit the RunaiConfig to adjust scheduler verbosity:

    kubectl edit runaiconfig runai -n runai
  2. Add or modify the following section under the scheduler settings:

    runai-scheduler:
      args:
        verbosity: 6

    This increases the verbosity level of the scheduler logs to provide more detailed output.

Warning: Enabling verbose logging can significantly increase disk space usage. Monitor your storage capacity and adjust the verbosity level as necessary.
