Understanding the cl-support Output File
The cl-support script generates a compressed archive file of useful information for troubleshooting. The system either creates the archive file automatically or you can create the archive file manually.
Automatic cl-support File
The system creates the cl-support archive file automatically for the following reasons:
- When there is a core dump file for any application (not specific to Cumulus Linux, but something all Linux distributions support), located in
/var/support/core. - When one of the monitored services fails for the first time after you reboot or power cycle the switch.
Manual cl-support File
To create the cl-support archive file manually, run the cl-support command:
cumulus@switch:~$ sudo cl-support
If the Cumulus Linux support team requests that you submit the output from cl-support to investigate issues you experience and you need to include security-sensitive information, such as the sudoers file, use the -s option:
cumulus@switch:~$ sudo cl-support -s
For information on the directories included in the cl-support archive, see:

/etcdirectory contains the largest number of files. - Troubleshooting Log Files. This guide highlights the most important log files to inspect. Keep in mind,
