Hej
I like to configure syslog. It seems that are more than one way to set up
syslog. I am asking for the comon way/steps to do that.
I have several use cases. To simplify I like to ask how to configure
syslog to write an infinity long log file in /var/log/.
Following steps:
1.) configure what messages
1.1) create own "syslog.conf" (define /var/log/myLog)
1.2) append it to "recipes-core/busybox"
2.) configure how to log
??
I found two possible places to do that:
@meta-poky
-> "meta-poky/recipes-core/busybox/busybox/poky-tiny/defconfig"
#######
#
# System Logging Utilities
#
CONFIG_SYSLOGD=y
CONFIG_FEATURE_ROTATE_LOGFILE=y
CONFIG_FEATURE_REMOTE_LOG=y
CONFIG_FEATURE_SYSLOGD_DUP=y
CONFIG_FEATURE_SYSLOGD_CFG=y
CONFIG_FEATURE_SYSLOGD_READ_BUFFER_SIZE=256
CONFIG_FEATURE_IPC_SYSLOG=y
CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE=16
CONFIG_LOGREAD=y
CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING=y
CONFIG_KLOGD=y
CONFIG_FEATURE_KLOGD_KLOGCTL=y
CONFIG_LOGGER=y
#######
>> add/change
"CONFIG_FEATURE_ROTATE_LOGFILE=n" by adding that line to
meta-mylayer/conf/layer.conf"
etc.
???
@ "/etc/syslog-startup.conf"
#######
# This configuration file is used by the busybox syslog init script,
# /etc/init.d/syslog[.busybox] to set syslog configuration at start time.
DESTINATION=file # log destinations (buffer file remote)
LOGFILE=/var/log/messages # where to log (file)
REMOTE=loghost:514 # where to log (syslog remote)
REDUCE=no # reduce-size logging
DROPDUPLICATES=no # whether to drop duplicate log entries
#ROTATESIZE=0 # rotate log if grown beyond X [kByte]
#ROTATEGENS=3 # keep X generations of rotated logs
BUFFERSIZE=64 # size of circular buffer [kByte]
FOREGROUND=no # run in foreground (don't use!)
#LOGLEVEL=5 # local log level (between 1 and 8)
#######
In the systemV init script "/etc/init.d/syslog.bussybox" the file
"/etc/syslog-startup.con" is read and used for configuration.
System behaviour:
When running my system, the log wraps when the logfile reaches 200kBytes.
One logfile + one log-rotate file is generated.
Any ideas how to archive that syslog writes an infinite long log-file?
I am working on the Yocto krogoth branch + meta-atmel / meta_openembedded
(@ krogoth too).
Best regards,
Stefan
