Hi there, Community!
This post brings you the solution to the issue that eSight disk usage is high. Please see below for more details.

ISSUE DESCRIPTION
Disk usage is high.
![]()
ISSUE ANALYSIS
After logging in to the OS, we found that the /opt usage reached 78%. eSight will report the alarm when the threshold exceeds 75%.
The previous time, our engineer deleted the backup files and only kept the 2 latest eSight backup files - about 24GB (24th & 25th Aug), then changed the backup file policy from 7 to 5.
Now, the system has 5 backup files, a total of 59 GB.

ROOT CAUSE
The /opt usage exceeds the 75% thethreshold.
SOLUTION
Delete the backup files and then change the backup files policy from 5 to 3 or less. If not solved, please don't be concerned about this alarm - normally, the system will not take more space for the backup files (the system only keeps 5 backup files).
And don’t copy any file to /opt.
That would be how to solve the issue when eSight disk usage is high.
