This section explains the collection of tech support logs using CLI.

To collect tech support logs using the Avi Load Balancer CLI:

  • In an Avi Load Balancer Controller cluster, one of the nodes is the leader or the primary node. Log in to the leader node using any ssh client, such as putty. 10.10.1.1 is the leader node in the following example:

login as: admin

  • From the shell prompt, run the command show tech-support serviceengine.

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

Note:

Avi-cluster1-SE1 is the Avi Load Balancer 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 /var/lib/avi/tech_support directory on the Controller leader node. Use cd command from the Avi Load Balancer CLI to get access to the directory. Check the debug logs and the other log files, which are available in compressed form with tar.gz extension.

The sample tech support log file is 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 - 15 Sep 2017. The following are the different options of tech support:
