Arbor Peakflow SP Disk Usage
Monitors disk usage on Arbor Peakflow SP devices. This
is based on a single percentage reported by the device,
this check doesn't know the absolute size of the disk.
The device reports detailed usage statistics in a generic
mib, handled by hr_fs but this is apparently not
officially supported by the vendor.
This check can be configured using the rule
"Filesystems (used space and growth)" but only the
regular levels, specified in percent, are supported.
The sole item is named "/".
One service is discovered.
