# Logging is controlled by following global variables:
|
|
# - @var kdump_stdloglvl - logging level to standard error (console output)
|
|
# - @var kdump_sysloglvl - logging level to syslog (by logger command)
|
|
# - @var kdump_kmsgloglvl - logging level to /dev/kmsg (only for boot-time)
|
|
# If any of the variables is not set, this function set it to default:
|
|
# - @var kdump_stdloglvl=4 (info)
|
|
# - @var kdump_sysloglvl=4 (info)
|
|
# - @var kdump_kmsgloglvl=0 (no logging)

# Logging levels: fatal(1),error(2),warn(3),info(4),debug(5),trace(6)

# to console and journald for debugging case.

# kdump_sysloglvl=5
