name. • Items vfs.dev.read and vfs.dev.write have gained support for LVM. Additionally, in previous versions of Zabbix only relative device name could be used (like sda). Now /dev/ prefix may also optionally examples of supported syntax: – vfs.dev.read[mapper/VolGroup01-LogVol00,sectors] – vfs.dev.read[VolGroup01/LogVol00,sectors] – vfs.dev.read[/dev/sda,operations] – vfs.dev.read[sdb,operations] • Items net Libraries. • SQLite Headers and Libraries. Note: Usually provided as part of mysql-dev, postgresql-dev, sqlite3-dev packages. NET-SNMP (or UCD-SNMP) library and header files. Required for SNMP support

Low-level discovery of block devices and their type is supported using a new built-in discovery key: vfs.dev.discovery The discovery will return a JSON with the values of two macros - {#DEVNAME} and {#DEVTYPE} respectively. These macros can be used to create item prototypes using the vfs.dev.read[] and vfs.dev.write[] agent items, i.e. vfs.dev.read[{#DEVNAME},sps]. See also: Discovery of block devices.
