gNMI Streaming

You can use gRPC Network Management Interface (gNMI) to collect system resource, interface, and counter information from Cumulus Linux and export it to your own gNMI client.

Configure the gNMI Agent

The netq-agent package includes the gNMI agent, which it disables by default. To enable the gNMI agent:

 cumulus@switch:~$ sudo systemctl enable netq-agent.service
 cumulus@switch:~$ sudo systemctl start netq-agent.service
 cumulus@switch:~$ netq config add agent gnmi-enable true

The gNMI agent listens over port 9339. You can change the default port in case you use that port in another application. The /etc/netq/netq.yml file stores the configuration.

Use the following commands to adjust the settings:

Disable the gNMI agent:

cumulus@switch:~$ netq config add agent gnmi-enable false

Change the default port over which the gNMI agent listens:

cumulus@switch:~$ netq config add agent gnmi-port <gnmi_port>

Restart the NetQ Agent to incorporate the configuration changes:
```
cumulus@switch:~$ netq config restart agent
```

The gNMI agent relies on the data it collects from the NVUE service. For complete data collection with gNMI, you must enable the NVUE service. To check the status of the nvued service, run the sudo systemctl status nvued.service command:

cumulus@switch:mgmt:~$ sudo systemctl status nvued.service
● nvued.service - NVIDIA User Experience Daemon
   Loaded: loaded (/lib/systemd/system/nvued.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2023-03-09 20:00:17 UTC; 6 days ago

If necessary, enable and start the service:

cumulus@switch:mgmt:~$ sudo systemctl enable nvued.service
cumulus@switch:mgmt:~$ sudo systemctl start nvued.service

Use the gNMI Agent Only

NVIDIA recommends that you collect data with both the gNMI and NetQ agents. However, if you do not want to collect data with both agents or you are not streaming data to NetQ, you can disable the NetQ agent. Cumulus Linux then sents data only to the gNMI agent.

To disable the NetQ agent:

cumulus@switch:~$ netq config add agent opta-enable false

You cannot disable both the NetQ and gNMI agent. If you enable both agents on Cumulus Linux and a NetQ server is unreachable, the switch does not send the data to gNMI from the following models:

openconfig-interfaces
openconfig-if-ethernet
openconfig-if-ethernet-ext
openconfig-system
nvidia-if-ethernet-ext

WJH, openconfig-platform, and openconfig-lldp data continue streaming to gNMI in this state. If you are only using gNMI and a NetQ telemetry server does not exist, disable the NetQ agent by setting opta-enable to false.

Supported Subscription Modes

Cumulus Linux supports the following gNMI subscription modes:

POLL mode
ONCE mode
STREAM mode, supported for ON_CHANGE subscriptions only

Collect WJH Data with gNMI

You can export What Just Happened (WJH) data from the NetQ agent to your own gNMI client. Refer to the nvidia-if-wjh-drop-aggregate reference YANG model, above.

Supported Features

The gNMI Agent supports Capabilities and STREAM subscribe requests for WJH events.

WJH Drop Reasons

The data that NetQ sends to the gNMI agent is in the form of WJH drop reasons. The SDK generates the drop reasons and Cumulus Linux stores them in the /usr/etc/wjh_lib_conf.xml file. Use this file as a guide to filter for specific reason types (L1, ACL, and so on), reason IDs, or event severeties.

Layer 1 Drop Reasons

gNMI Client Requests

You can use your gNMI client on a host to request capabilities and data to which the Agent subscribes. The examples below use the gNMIc client..

The following example shows a gNMIc STREAM request for WJH data:

gnmic -a 10.209.37.121:9339 -u cumulus -p ****** --skip-verify subscribe --path "wjh/aggregate/l2/reasons/reason[id=209][severity=error]/state/drop" --mode stream --prefix "/interfaces/interface[name=swp8]/" --target netq

      }
    }
  ]
}

The following example shows a gNMIc ONCE mode request for interface port speed:

        "interfaces/interface/ethernet/state/port-speed": "SPEED_1GB"
      }
    }
  ]
}

The following example shows a gNMIc POLL mode request for interface status:

gnmic -a 10.209.37.121:9339 -u cumulus -p ****** --skip-verify subscribe --path "state/oper-status" --mode poll --prefix "/interfaces/interface[name=swp1]/" --target netq
