How to Adjust the Log Size and Rotate Options


Back to Top

CLI: Access the command line interface (CLI). You can do this using the CLI button in the GUI or by using a program such as PuTTY.

The EdgeRouter is automatically set up to rotate the log messages. The default log options can be viewed by running the below command:

cat /etc/logrotate.d/messages
/var/log/messages {
missingok
notifempty
rotate 10
size=1000k
postrotate
invoke-rc.d rsyslog reload >/dev/null
endscript
}
NOTE: It is recommended to set up a remote syslog server over increasing the log size + files when extensive logging is needed.

Modify the log options by running the commands below:

configure
set system syslog global archive files <nr>
set system syslog global archive size <kbytes>
commit ; save
