Hello everyone

I have a question regarding the behavior of Kibana in a situation where the disk is full

We've separated the logs to be on another disk :

root@brkibana:~# df -hT  
Filesystem Type Size Used Avail Use% Mounted on  
udev devtmpfs 3.9G 0 3.9G 0% /dev  
tmpfs tmpfs 798M 81M 718M 11% /run  
/dev/mapper/brkibana--vg-root ext4 25G 9.2G 14G 40% /  
tmpfs tmpfs 3.9G 0 3.9G 0% /dev/shm  
tmpfs tmpfs 5.0M 0 5.0M 0% /run/lock  
tmpfs tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup  
**/dev/sdb1 ext4 115G 108G 1.3G 99% /logs**  
/dev/sda1 ext2 472M 58M 390M 13% /boot  
tmpfs tmpfs 798M 0 798M 0% /run/user/0

And as you see , the log disk is almost full  
Will it overwrite old data by default ? if not , is it possible to configure if the disk is on 90% usage then overwrite old data ?

Hello Abed,

It sounds like you're looking for a log rotation utility. It doesn't appear we have anything that handles this natively, but there are some third-part utilities which could help. See this thread for reference:

> [@Kibana Log Rotation](https://discuss.elastic.co/t/kibana-log-rotation/139764):

> I have set logging.destin kibana.yml, but the log file grows rapidly to the point where in just a few weeks some text editors (e.g. Notepad++) can't open the file because its so big. Is there a way to rotate the log file so that, say, each day the log file name is changed?

Regards,  
Aaron

Hi Aaron

Thanks  
But does the Kibana overwrite old logs when disk is full automatically ?
