[mohit-singhal]

Hi All,

We are experiencing high disk space usage on the root partition of Panorama.

Critical alerts on Panorama is showing "Disk Usage for / exceeds limit, 100 percent in use, cleaning filesystem".

Output of "show system files" is as follows: 

@panorama> show system files

/var/cores/:

I found one KB article related to this but it shows how to clear the disk space.

Could you please assist:

Can we configure if root partition reaches to 80% then it start cleaning files system automatically and what would be the impact on logging of this condition?

Why the core files are getting generated daily?

What can be done to fix this issue?

Is there any configuration can be done on Panorama to avoid root partition high disk usage?

Please let me know if you need further information.
