Analyze the problem of Zabbix 5.0 disk automatic discovery and read-write monitoring

Automatically discover disks

Configuration Key Values

Note: This key value is only supported on Linux platforms.

This discovery key returns two macros:

• {#DEVNAME} : device name
• {#DEVTYPE} : Device type

For example:

[ 
   { 
      "{#DEVNAME}":"loop1",
      "{#DEVTYPE}":"disk"
   },
   { 
      "{#DEVNAME}":"dm-0",
      "{#DEVTYPE}":"disk"
   },
   { 
      "{#DEVNAME}":"sda",
      "{#DEVTYPE}":"disk"
   },
   { 
      "{#DEVNAME}":"sda1",
      "{#DEVTYPE}":"partition"
   }
]

Configuring Filters

Used to filter device type and device name, usually the disk name is sd* or vd* .

Test verification

Add disk read and write rate monitoring

Disk read and write key values:

vfs.dev.read[<device>,<type>,<mode>]
vfs.dev.write[<device>,<type>,<mode>]

illustrate:

device - disk device (default is all )

type - possible values: sectors , operations , bytes , sps , ops , bps
Because the default value varies between operating systems, this parameter must be specified.
sps , ops , bps represent: sectors, operations, bytes per second, respectively.

mode - possible values: avg1 (1 minute average, default), avg5 , avg15 .
This parameter supports only these類型: sps, ops, bps.

Note: The default value of the "type" parameter is different for different operating systems.

Therefore, the monitoring key value of disk read and write can be configured as:

• Read: vfs.dev.read[{#DEVNAME},sps]
• Write: vfs.dev.write[{#DEVNAME},sps]

The {#DEVNAME} macro is allowed when the key value is vfs.dev.read[] and vfs.dev.write[] .
