You can configure the Linux Machine Agent to calculate the following metrics similar to using the Linux df

• Servers > Volumes > /opt > Disk Usage
• Metric Browser > Disks and Partitions > <partition> > Space Available
• Metric Browser > Disks and Partitions > <partition> > Space Used

Linux includes a mechanism for reserving some disk space to ensure that the system remains functioning even if non-privileged users consume all other disk space. By default, these metrics include 5% of reserved space.

By default, the flag -Dappdynamics.machine.agent.extensions.calcVolumeFreeAndUsedWithDfCommand true

To override this default, set -Dappdynamics.machine.agent.extensions.calcVolumeFreeAndUsedWithDfCommand false

This feature is supported for Linux versions of the Machine Agent only.
