简单介绍

在使用zabbix的过程中，我们会发现zabbix的功能越发强大，完全可以满足企业的各种需求，我们可以利用自定义模板，将我们需要监控的监控项自定义到模板中，并设置好阈值触发器，并设置好告警等等，可以满足我们的所有需求。

配置参考

自动发现部分

创建模板——》Discovery——》设置

网络自动发现

1 2 3 4 5 6	name: Network interface discovery Key: net.if.discovery Filters Label Macro: {#IFNAME} Regular expression: @Network interfaces for discovery

磁盘自动发现

1 2 3 4 5 6 7 8 9 10	name: Mounted filesystem discovery Key: vfs.fs.discovery Filters A Label Macro: {#FSNAME} Regular expression: @File name for discovery B Label Macro: {#FSTYPE} Regular expression: @File systems for discovery

网络

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16	出网： Name： Outgoing network traffic on $1 Key: net.if.out[{#IFNAME}] Type of information: Numeric(unsigned) Data type: Decimal units: bps Use custom multiplier: 8 入网： Name: Incoming network traffic on $1 Key: net.if.in[{#IFNAME}] Type of information: Numeric(unsigned) Data type: Decimal units: bps Use custom multiplier: 8

磁盘

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

free disk Name: Free disk space on $1 (percentage) Key: vfs.fs.size[{#FSNAME},pfree] Type of information: Numeric(float) units: % free inodes Name: Free inodes on $1 (percentage) Key: vfs.fs.inode[{#FSNAME},pfree] Type of information: Numeric(float) units: % total disk Name: Total disk space on $1 Key: vfs.fs.size[{#FSNAME},total] Type of information: Numeric(unsigned) Data type: Decimal units: B use disk Name: Used disk space on $1 Key: vfs.fs.size[{#FSNAME},used] Type of information: Numeric(unsigned) Data type: Decimal units: B

磁盘阈值报警规则

1 2 3 4 5 6 7 8

Name: {HOST.NAME} Free disk space is less than 5% on volume {#FSNAME} Expression: {Template_base_xs:vfs.fs.size[{#FSNAME},pfree].last(0)}<5 Name: {HOST.NAME} Free disk space is less than 15% on volume {#FSNAME} Expression: {Template_base_xs:vfs.fs.size[{#FSNAME},pfree].last(0)}<15 Name: {HOST.NAME} Free inodes is less than 15% on volume {#FSNAME} Expression: {Template_base_xs:vfs.fs.inode[{#FSNAME},pfree].last(0)}<15

以上为自动发现项，包括网络和磁盘，因为很多情况下我们不知道有多少块网卡，或者网卡名叫什么，或者有多少块磁盘等情况，下面是一些zabbix自带的检测系统的一些常用项的监控项配置

添加其他监控项

主机存活性

1 2 3 4 5	Name: Agent ping Key: agent.ping Type of information: Numeric(unsigned) Data type: Decimal units:

CPU相关

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60

进程数

1 2 3 4 5 6 7 8 9	Name: Processes number of running Key: proc.num[,,run] Type of information: Numeric(unsigned) units: Name: Processes total number Key: proc.num[] Type of information: Numeric(unsigned) units:

负载

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15	Name: Processor load (1 min average) Key: system.cpu.load[,avg1] Type of information: Numeric(float) units: Name: Processor load (5 min average) Key: system.cpu.load[,avg5] Type of information: Numeric(float) units: Name: Processor load (15 min average) Key: system.cpu.load[,avg15] Type of information: Numeric(float) units:

自定义key，获取要监控项的值

脚本参考：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

#!/bin/bash port="9998" Mem() { free -m | grep Mem | awk '{printf ("%.2f\n"),$3/$2*100}' } Disk() { df -h | grep "/dev/vd" | awk '{print $5}' | awk -F '%' '{print $1}' | head -1 } Nginx() { sudo netstat -antplu |grep nginx | wc -l } Php() { ps auxf |grep php-fpm | grep -v grep | wc -l } Mysql() { sudo netstat -antplu |grep mysql | wc -l } Redis() { sudo netstat -antplu | grep redis | grep $port | wc -l } $1

zabbix配置自动发现规则，用来自动发现机器，并把机器添加到组里，并链接模板等操作。
