Writing logs to the internal hard drive

RouterOS General
1

We should keep logs for many purposes but we need them for just archiving. It’ll be good to use the internal hard drive (an extra one other than the os drive) as a log disk just like the web proxy package using that device for proxying. We can take them any time we like just a backup file over ftp.

If you do this the index gets larger and larger, and the performance of the router could be impacted if you view the log from the ROS.

Use a syslog server, it is optomized for this type of activity.

use DUDE.

I don’t want to use the logs in the routeros. I just want to write inside the device. With that, you won’t be affected by any third party device failure and you can reach your archive any time to export out side.

We’re already using syslog stuff but you need a second device other than routeros and you have to maintain it for availability.

for now, only this is possible. limited to system drive:


[normis@demo2.mt.lv] > log print file=ssss
[normis@demo2.mt.lv] > file pri
 # NAME                   TYPE                  SIZE       CREATION-TIME
 0 console.rif            .rif file             416620     oct/02/2007 14:29:44
 1 supout.rif             .rif file             384316     sep/25/2007 22:31:57
 2 ssss.txt               .txt file             9327       oct/04/2007 13:06:59

Can an external one be used or is an internal hard drive preferred?

it’s changed now. you can now save it to any disk. just change the logging action “disk” to set the drive you want.

To log everything to file, add new log action:

/system logging action add name=file target=disk
disk-file-name=log

>
> then make everything log using this new action:
>
> ```text
/system logging action=file

you can log only errors there by issuing command:

/system logging topics=error action=file

>
> This will log into files log.0.txt and log.1.txt. You can

> disk-lines-per-file. <file>.0.txt is active file were new
> logs are going to be appended and once it size will
