DOCA BlueMan Service

NVIDIA DOCA BlueMan Service Guide

This document provides instructions on how to use the DOCA BlueMan service on top of NVIDIA® BlueField® DPU.

DOCA BlueMan runs in the DPU as a standalone web dashboard and consolidates all the basic information, health, and telemetry counters into a single interface.

All the information that BlueMan provides is gathered from the DOCA Telemetry Service (DTS), starting from DTS version 1.11.1-doca1.5.1.

  • BlueField image version 3.9.3.1 or higher
  • DTS and the DOCA Privileged Executer (DPE) daemon must be up and running
    Note:

    Refer to the NVIDIA DOCA Telemetry Service Guide for more.

2.1. Verifying DTS Status

All the information that BlueMan provides is gathered from DTS. Verify that the state of the DTS pod is ready:

Copy
Copied!
            

$ crictl pods --name doca-telemetry-service


Verify that the state of the DTS container is running:

Copy
Copied!
            

$ crictl ps --name doca-telemetry-service

2.2. Verifying DPE Status

All the information that DTS gathers for BlueMan is from the the DPE daemon.

Verify that the DPE daemon is active:

Copy
Copied!
            

$ systemctl is-active dpe.service active


If the daemon is inactive, activate it by starting the dpe.service:

Copy
Copied!
            

$ systemctl start dpe.service

For more information about the deployment of DOCA containers on top of the BlueField DPU, refer to the NVIDIA DOCA Container Deployment Guide.

3.1. DOCA Service on NGC

BlueMan is available on NGC, NVIDIA's container catalog. Service-specific configuration steps and deployment instructions can be found under the service's container page.

3.2. Default Deployment – BlueField BSP

BlueMan service is located under /opt/mellanox/doca/services/blueman/. The following is a list of the files under the BlueMan directory:

Copy
Copied!
            

doca_blueman_fe_service_<version>-doca<version>_arm64.tar doca_blueman_conv_service_<version>-doca<version>_arm64.tar doca_blueman_standalone.yaml bring_up_doca_blueman_service.sh

3.3. Enabling BlueMan Service

3.3.1. Using Script

Run bring_up_doca_blueman_service.sh:

Copy
Copied!
            

$ /opt/mellanox/doca/services/blueman/bring_up_doca_blueman_service.sh

3.3.2. Manual Procedure

  1. Import images to crictl images:
    Copy
    Copied!
                

    $ cd /opt/mellanox/doca/services/blueman/ $ ctr --namespace k8s.io image import doca_blueman_fe_service_<version>-doca<version>_arm64.tar $ ctr --namespace k8s.io image import doca_blueman_conv_service_<version>-doca<version>_arm64.tar

  2. Verify that the DPE daemon is active:
    Copy
    Copied!
                

    $ systemctl is-active dpe.service active

    If the daemon is inactive, activate it by starting the dpe.service:
    Copy
    Copied!
                

    $ systemctl start dpe.service


  3. Copy blueman_standalone.yaml to /etc/kubelet.d/:
    Copy
    Copied!
                

    $ cp doca_blueman_standalone.yaml /etc/kubelet.d/

3.4. Verifying Deployment Success

  1. Verify that the DPE daemon is active:
    Copy
    Copied!
                

    $ systemctl is-active dpe.service

  2. Verify that the state of the DTS container is running:
    Copy
    Copied!
                

    $ crictl ps --name doca-telemetry-service

  3. Verify that the state of the BlueMan service container is running:
    Copy
    Copied!
                

    $ crictl ps --name doca-blueman-fe $ crictl ps --name doca-blueman-conv

The configuration of the BlueMan back end is located under /opt/mellanox/doca/services/telemetry/config/blueman_config.ini. Users can interact with the blueman_config.inifile which contains the default range values of the Pass, Warning, and Failed categories which are used in the health page. Changing these values gets reflected in the BlueMan webpage within 60 seconds. Example of blueman_config.ini:

Copy
Copied!
            

;Health Cpu usages Pass, warning, Failed [Health:CPU_Usages:Pass] range = 0,80 [Health:CPU_Usages:Warning] range = 80,90 [Health:CPU_Usages:Failed] range = 90,100

  • Info
    • General info – OS name, kernel, part number, serial number, DOCA version, driver, board ID, etc.
    • Installed packages – list of all installed packages on the DPU including their version
    • CPU info – vendor, cores, model, etc.
    • FW info – all the mlxconfig parameters with default/current/next boot data
    • DPU operation mode
  • Health
    • System service
    • Kernel modules
    • Dmesg
    • DOCA services
    • Port status of the PF and OOB
    • Core usage and processes running on each core
    • Memory usage
    • Disk usage
    • Temperature
  • Telemetry – all telemetry counters that come from DTS according to the enabled providers displayed on tables
    • Users have the ability to build graphs of specific counters

To log into BlueMan, enter the IP address of the DPU's OOB interface (http://<DPU_OOB_IP>) to a web browser located in the same network as the DPU.

The login credentials to use are the same pair used for the SSH connection to the DPU.

For general troubleshooting, refer to NVIDIA DOCA Troubleshooting Guide.

For container-related troubleshooting, refer to the "Troubleshooting" section in the NVIDIA DOCA Container Deployment Guide.

The following are additional troubleshooting tips for DOCA BlueMan:

  • The following error message in the login page signifies a failure to connect to the DPE daemon: "The service is currently unavailable. Please check server up and running."
    1. Restart the DPE daemon:
      Copy
      Copied!
                  

      $ systemctl restart dpe.service

    2. Verify that DTS is up and running by following the instructions in section Verifying DTS Status.
  • If the message "Invalid Credentials" appears in the login page, verify that the username and password are the same ones used to SSH to the DPU.
  • If all of the above is configured as expected and there is still some failure to log in, it is recommended to check if there are any firewall rules that block the connection.
  • For other issues, check the /var/log/syslog and /var/log/doca/telemetry/blueman_service.log log file.
