Subject: [PATCH] [kdump] Create AzureKDump class
|
||
|
|
|
||
|
|
This change collects kdump information for Azure Linux.
|
||
|
|
|
||
|
|
With this change, we will check the 'path' variable in /etc/kdump.conf
|
||
|
|
to check where information is being dumped.
|
||
|
|
|
||
|
|
If get_vm_core is set to true, collect the latest vm core created
|
||
|
|
in the last 24 hours that is <= 2GB
|
||
|
