Monitoring

Linux File Systems reporting more than 100% usage

Thresholds for disk space calculations to reflect the view of a non-root user.

Most filesystems reserve 5% of file system space for root use only, so that there is some ability to move things and copy them if the filesystem gets full. This percentage is generally tunable on file system creation, but we assume the default of 5%.

The reason LogicMonitor reports the file system capacity from the perspective of a non-root user is to prevent the situation where LogicMonitor shows that there is 5% free space, when a non-root user would experience a file system full error. You can change this if you just want the absolute usage numbers. The math for these datapoints are specified as (StorageUsed/(StorageSize*0.95)*100), you would remove the .95 factor.
