Cumulus Linux Support File

Follow

Cumulus Linux generates support files called cl-support whenever issues are detected. The cl-support file is located in the /var/support directory and is named cl_support_xxx.txz.

There are three ways cl-support is generated:

  • If switchd or any other process generates a core file (located in /var/support/core), then the cl-support file is generated.
  • After the first failure of one of the following monitored services since the switch was rebooted or power cycled:
    • clagd
    • openvswitch-vtep
    • portwd
    • ptmd
    • quagga
    • rdnbrd
    • switchd
    • vxrd
    • vxsnd
  • A cl-support file can be triggered by issuing the cl-support command. Run cl-support -h for more information about how to generate it manually.
    cumulus@switch:/var/log$ sudo cl-support -h
    Usage: cl-support [-h] [-s] [-t] [-v] [reason]...

    Args:
    [reason]: Optional reason to give for invoking cl-support.
    Saved into tarball's cmdline.args file.
    Options:
