Install NIC and DPU Agents

Installing NetQ telemetry agents on your hosts with NVIDIA ConnectX adapters and NVIDIA BlueField data processing units (DPUs) allows you to track inventory data and statistics across devices. The DOCA Telemetry Service (DTS) is the agent that runs on hosts and DPUs to collect data.

Install DTS on ConnectX Hosts

To install and configure the DOCA Telemetry Service container on a host with ConnectX adapters, perform the following steps:

1. Obtain the DTS container image path from the NGC catalog. Select Get Container, then View all tags. Copy the 1.16.1-doca2.6.0-host image path.

2. Initialize the DTS container with Docker on the host. Use the image path obtained in the previous step for the DTS_IMAGE variable and configure the IP address of your NetQ server for the -i option:

export DTS_IMAGE=nvcr.io/nvidia/doca/doca_telemetry:1.16.1-doca2.6.0-host
docker run -v "/opt/mellanox/doca/services/telemetry/config:/config" --rm --name doca-telemetry-init -ti $DTS_IMAGE /bin/bash -c "DTS_CONFIG_DIR=host_netq /usr/bin/telemetry-init.sh && /usr/bin/enable-fluent-forward.sh -i=10.10.10.1 -p=30001"

3. Run the DTS container on the host:

docker run -d --net=host                                                              \
              --privileged                                                            \
              -v "/opt/mellanox/doca/services/telemetry/config:/config"               \
              -v "/opt/mellanox/doca/services/telemetry/ipc_sockets:/tmp/ipc_sockets" \
              -v "/opt/mellanox/doca/services/telemetry/data:/data"                   \
              --rm --name doca-telemetry -it $DTS_IMAGE /usr/bin/telemetry-run.sh

Modify Scrape Interval

The Prometheus adapter pod in NetQ collects statistics from ConnectX adapters in your network. The default scrape interval is every minute. If you want to change the frequency of the scrape interval, make your adjustments, then restart the netq-prom-adapter pod to begin collecting data with the updated parameters:

1. Log in to your NetQ VM via SSH.

2. Edit the Prometheus ConfigMap with the kubectl edit cm prometheus-config command.

3. Edit the scrape_interval parameter.

4. Retrieve the current pod name with the kubectl get pods | grep netq-prom command:

cumulus@netq-server:~$ kubectl get pods | grep netq-prom
netq-prom-adapter-ffd9b874d-hxhbz                    2/2     Running   0          3h50m

5. Restart the pod by deleting the running pod:

kubectl delete pod netq-prom-adapter-ffd9b874d-hxhbz

Install DTS on DPUs

To install and configure the DOCA Telemetry Service (DTS) container on a DPU, perform the following steps:

1. Obtain the DTS container image path from the NGC catalog. Select Get Container, then View all tags. Copy the 1.15.5-doca2.5.0 image path.

2. Retrieve the container yaml configuration file onto the host. Use the path specified in the Adjusting the .yaml Configuration section in the NGC instructions. Copy it to /etc/kubelet.d/doca_telemetry_standalone.yaml:

wget --content-disposition https://api.ngc.nvidia.com/v2/resources/nvidia/doca/doca_container_configs/versions/2.0.2v1/files/configs/2.0.2/doca_telemetry.yaml -O /etc/kubelet.d/doca_telemetry_standalone.yaml

3. Edit the image in both the containers and initContainers sections of the /etc/kubelet.d/doca_telemetry_standalone.yaml file to set the container image path retrieved in step 1.

4. Edit the command in the initContainers section of the /etc/kubelet.d/doca_telemetry_standalone.yaml file to set the DTS_CONFIG_DIR parameter to inventory_netq. Configure the fluent forwarding -i option to your NetQ server IP address and the -p option to 30001:

  initContainers:
...
      command: ["/bin/bash", "-c", "DTS_CONFIG_DIR=inventory_netq /usr/bin/telemetry-init.sh && /usr/bin/enable-fluent-forward.sh -i=10.10.10.1 -p=30001"]

5. Restart the DPE service with the service dpe restart command.
