Troubleshoot NetQ

This page describes how to troubleshoot issues with NetQ itself. If you need additional assistance, contact the NVIDIA support team with the support file you created using the steps outlined on this page.

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.

Troubleshoot NetQ Installation and Upgrade Issues

Before you attempt a NetQ installation or upgrade, verify that your system meets the minimum VM requirements for your deployment type.

If an upgrade or installation process stalls or fails, run the netq bootstrap reset command to stop the process, followed by the netq install command to re-attempt the installation or upgrade.

Error MessageDeployment TypeSolution
Cannot upgrade a non-bootstrapped NetQ server. Please reset the cluster and re-install.Only a server that has been bootstrapped and has a valid /etc/app-release file can be upgraded.
1. Run the netq bootstrap reset command.
2. Run the netq install command according to your deployment type.
Unable to get response from admin app.Re-run the netq upgrade bundle <text-bundle-url> command. If the retry fails with same error, reset the server and run the install command:
1. Run the netq bootstrap reset command.
2. Run the netq install command according to your deployment type.
Unable to get response from kubernetes api server.Re-run the netq upgrade bundle <text-bundle-url> command. If the retry fails with same error, reset the server and run the install command:
1. Run the netq bootstrap reset command
2. Run the netq install command according to your deployment type.
Cluster vip is an invalid parameter for standalone upgrade.Single serverRemove the cluster-vip option from the netq upgrade bundle command.
Please provide cluster-vip option and run command.HA clusterInclude the cluster-vip option in the netq upgrade bundle command.
Could not find admin app pod, please re-run the command.Re-run the netq upgrade bundle <text-bundle-url> command.
Could not upgrade server, unable to restore got exception: {}On-premisesThe backup/restore option is only applicable for on-premises deployments which use self-signed certificates.
Error MessageDeployment TypeSolution
NetQ is operational with version: {}. Run the bootstrap reset before re-installing NetQ.NetQ has previously been installed. To install a new version:
1. Run the netq bootstrap reset command.
2. Run the netq install command.

Package {} with version {} must be installed.Make sure the netq-apps version is the same as the tarball version.
Master node is already bootstrappedRun the netq bootstrap rest command, followed by the netq install command to re-attempt the installation.

Installation and Upgrade Hook Scripts

NVIDIA might provide hook scripts to patch issues encountered during a NetQ installation or upgrade. When you run the netq install or netq upgrade command, NetQ checks for specific hook script filenames in the /usr/bin directory. The expected filenames for NetQ 4.12.0 are:

  • Pre-install script: /usr/bin/pre_install_4.12.0.sh
  • Post-install script: /usr/bin/post_install_4.12.0.sh
  • Pre-upgrade script: /usr/bin/pre_upgrade_4.12.0.sh
  • Post-upgrade script: /usr/bin/post_upgrade_4.12.0.sh

After placing the script in the /usr/bin directory, set executable permissions with the chmod +x /usr/bin/<filename> command:

cumulus@netq-server:~$ chmod +x /usr/bin/pre_install_4.12.0.sh

After copying the script to the expected path and setting it to executable, the script will run during the next installation or upgrade attempt.

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
[sudo] password for cumulus:

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.
