5. Trigger trigger

Cpu usage monitoring

System.cpu.util [,]

System.cpu.util [0,user,avg5]

The specific number of cpu is the specific core of CPU.

Type is the different state value of CPU.

Idle, nice, user (default), system (default for Windows), iowait, interrupt, softirq, steal

Where idle means idle, and user means that the user uses

The final avg5 represents an average value of every 5 minutes. A null value indicates the current value. To change it to an average of 15 minutes, you only need to write it as avg15.

The current CPU usage is written as system.cpu.util [, user], which is the same as system.cpu.util [, idle]

Memory monitoring

Vm.memory.size []

Total (default), active,anon, buffers, cached, exec, file, free

Inactive pinned, shared, wired, used, pused, available, pavailable

Trigger severity is used to display the level of Trigger, and zabbix supports several alert levels.

Level meaning color

Not classified unknown Grey

Information system Information Light green

Warning warns yellow

Average General question orange

High seriously warns red

Disaster data loss Bright red

The purpose of classification: 1 different alarms represent different colors and 2 sound alarms, and different levels can be alerted with different sounds. 3 different levels use different methods of alarm notification, such as sms email. ..

Units supported by trigger

S seconds h hours

M minutes d days

W week K Kilo

M mega G giga

T tera P peta

E exa Z zetta

Y yotta

Instance: Configure- > Hosts- > triggers

Example 1: monitoring of disk partitions

Vfs.fs.size [fs,]

Mode, the default is total, and the rest is the percentage of free,used,pfree,pused,p, here in%

The corresponding units are B (which means Byte here) and%, if the monitoring size: Numeric (unsigned) Decimal

Capture the partition situation of the client on the zabbix server

# zabbix_get-s 192.168.36.167-p 10050-k "vfs.fs.size [/ dev/sda2,used]"

241664

Create a new item to monitor partition / dev/sda2 usage

Create a trigger and alarm when the host / dev/sda2 usage space is more than 20%.

For example, 2:/etc/passwd changes the diff function.

First add an item:Configure- > Hosts- > Items, which is used by the project to detect the file MD5 value.

Call the diff function

Example 3: if the network card traffic continues to exceed 100k in 5 minutes, the alarm will be given.
