To know more about the leader node in an Avi Controller cluster, refer to Overview of the Controller Cluster. To know more about SSH key generation, refer to Avi CLI access.

  • Type shell command, and enter your credentials.

admin@avi-cntrl1:~$ shell
Login: admin
  • From the shell prompt, run the command show tech-support serviceengine.

    The command show tech-support serviceengine create debug logs for the particular SE.

    Note: For reference, Avi-Cluster1-SE1 is the Avi SE for which we want to collect the debug logs.

[admin:avi-cntrl1]: > show tech-support serviceengine Avi-cluster1-SE1
  • This command generates core files and other debug logs, which are stored in /tmp directory on the Avi Controller leader node. Use cd/tmp command from the Avi CLI to get access to the tmp directory. Check the debug logs and the other log files, which are available in compressed form with tar.gz extension.

Sample tech support log file: debuglogs.20170915-124030.tar.gz The number 20170915 in the log file debuglogs.20170915-124030.tar.gz represents the date of generation of the log files, i.e., 15 Sep 2017.

Additional Information

The following command collects the debug logs on each of the Avi Controller nodes. This option keeps the collected tech support bundle to a minimal size. The option is especially useful if the core archive bundles that are present have already been uploaded and fixed.

show tech-support debuglogs

The following command includes the collection of the core archive bundles.

show tech-support debuglogs filter include_archive

If you have external connectivity to AWS S3 from the Avi Controller, you can upload the tech support information to the Avi customer support S3 bucket, using the following command:

upload tech-support debuglogs
