Trying to determine free space on mounted filesystems, including reserved space.

[zabbix_mouse_123]

Zabbix Server Version: 7.0.17

As the title suggests, I am trying to create an item that determines the free space of the mounted file systems on some Ubuntu servers, each with a couple of mounted file systems.

As it stands currently, the hosts are inheriting a template named 'mounted filesystem discovery' whose Key=vfs.fs.discovery.
This template has 4 item prototypes, whose keys are:

vfs.fs.inode[{#FSNAME},pfree]

vfs.fs.size[{#FSNAME},pused]

vfs.fs.size[{#FSNAME},total]

Hello

There is only a prototype item for free space excluding the reserved space, but since you specifically want to include the reserved space, it would make sense to create it as a calculated item with a formula: vfs.fs.size[{#FSNAME},total] - vfs.fs.size[{#FSNAME},used].

Correction: the 'last' function would be needed here though:

last(vfs.fs.size[{#FSNAME},total]) - last(vfs.fs.size[{#FSNAME},used])
