description: |
This is an official Linux template. It requires Zabbix agent 7.0 or newer.
Notes on filesystem (FS) discovery:
- The ext4/3/2 filesystem reserves space for privileged usage, typically set at 5% by default.
- BTRFS allocates a default of 10% of the volume for its own needs.
- To mitigate potential disasters, FS usage triggers are based on the maximum available space.
- Utilization formula: 'pused = 100 - 100 * (available / total - free + available)'
- The FS utilization chart, derived from graph prototypes, reflects FS reserved space as the difference between used and available space from the total volume.

This trigger expression works as follows:
1. It can be triggered if the operations status is down.
2. `{$IFCONTROL:"{#IFNAME}"}=1` - a user can redefine the context macro to "0", marking this interface as not important. No new trigger will be fired if this interface is down.
3. `last(/TEMPLATE_NAME/METRIC,#1)<>last(/TEMPLATE_NAME/METRIC,#2)` - the trigger fires only if the operational status was up to (1) sometime before (so, does not fire for "eternal off" interfaces.)
WARNING: if closed manually - it will not fire again on the next poll, because of .diff.

It indicates the latest or current speed value of the interface. The value is an integer representing the link speed expressed in bits/sec.
This attribute is only valid for the interfaces that implement the ethtool `get_link_ksettings` method (mostly Ethernet).
