Troubleshoot NetQ

This page describes how to generate a support file for the NVIDIA support team to help troubleshoot issues with NetQ itself.

Browse Configuration and Log Files

The following configuration and log files contain information that can help with troubleshooting:

FileDescription
/etc/netq/netq.ymlThe NetQ configuration file. This file appears only if you installed either the netq-apps package or the NetQ Agent on the system.
/var/log/netqd.logThe NetQ daemon log file for the NetQ CLI. This log file appears only if you installed the netq-apps package on the system.
/var/log/netq-agent.logThe NetQ Agent log file. This log file appears only if you installed the NetQ Agent on the system.

Check NetQ System Installation Status

The netq show status verbose command shows the status of NetQ components after installation. Use this command to validate NetQ system readiness:

Verify Connectivity between Agents and Appliances

The sudo opta-info.py command displays the status of and connectivity between agents and appliances. This command is typically used when debugging NetQ.

In the output below, the Opta Health Status column displays a healthy status, which indicates that the appliance is functioning properly. The Opta-Gateway Channel Status column displays the connectivity status between the appliance and cloud endpoint. The Agent ID column displays the switches connected to the appliance.

cumulus@netq-appliance:~$ sudo opta-info.py

Generate a Support File on the NetQ System

The opta-support command generates information for troubleshooting issues with NetQ. It provides information about the NetQ Platform configuration and runtime statistics as well as output from the docker ps command.

cumulus@server:~$ sudo opta-support
Please send /var/support/opta_support_server_2021119_165552.txz to Nvidia support.

To export network validation check data in addition to OPTA health data to the support bundle, the NetQ CLI must be activated with AuthKeys. If the CLI access key is not activated, the command output displays a notification and data collection excludes netq show output:

cumulus@server:~$ sudo opta-support
Access key is not found. Please check the access key entered or generate a fresh access_key,secret_key pair and add it to the CLI configuration
Proceeding with opta-support generation without netq show outputs
Please send /var/support/opta_support_server_20211122_22259.txz to Nvidia support.

Generate a Support File on Switches and Hosts

The netq-support command generates information for troubleshooting NetQ issues on a host or switch. Similar to collecting a support bundle on the NetQ system, the NVIDIA support team might request this output to gather more information about switch and host status.

When you run the netq-support command on a switch running Cumulus Linux, a cl-support file will also be created and bundled within the NetQ support archive:

cumulus@switch:mgmt:~$ sudo netq-support
Collecting cl-support...
Collecting netq-support...
Please send /var/support/netq_support_switch_20221220_16188.txz to Nvidia support.
