Log Collection Steps

1. Log in with SSH to any CVM using terminal emulators such as Tera Term or Putty.
   Set up to save the output logs with each tool feature.

   NOTE: You must log in with username: Nutanix and password: nutanix/4u.
   If you log in as other users, you are not able to gather the required information due to the permission issue.

2. Execute the following command to obtain output results.
   $ cluster status: Display the service operation status of the entire Cluster
   $ ncc health_checks run_all: Execute a health check for the entire Cluster and display results
   $ ncli alert history duration=30: Display Alert lists for last 30 days
   $ ncli cluster info: Display cluster UUID and current AOS version
   $ nodetool -h 0 ring: Display current metadata ring status
   $ ncli cluster get-domain-fault-tolerance-status type=node: Display current fault tolerance status
   $ ncli license get-license: Display the current license information

3. Execute the following command and collect the output file using software such as WinSCP or using SCP command.
   The operation log of the entire cluster is output and saved to /home/nutanix/data/logbay/bundles as NTNX-Log-YYYY-MM-DD-XXXXXXXXXXXXXXXXXXX-XXXXXXXXXX-PE.zip.

   NOTE: This command is available in NCC version 3.7.1 and later.
   You can know the current NCC version by running the command on CVM.
   $ ncc --version
   If the current NCC version is lower than 3.7, please skip this step.

   NOTE: It uses the time zone set up in CVM.
   Access with SSH to CVM, and ensure the timezone in advance with date command.

   NOTE: Use the following options to mask the unique information such as username, container name, and IP.
   $ logbay collect --aggregate=true --anonymize=True

   NOTE: The following option can specify the CVM to collect logs. If there are so many configuration nodes and it makes the log size huge, please utilize this option.
   Example: Collect logs of CVM IP address 10.10.70.172 and 10.10.70.173
   $ logbay collect --aggregate=true --src 10.10.70.172,10.10.70.173
