zabbix-get

安装zabbix-get软件

zabbix server可以去agent获取数据--》pull 拉

[root@zabbix ~]# yum install zabbix-get -y

[root@zabbix ~]# zabbix_get -s 192.168.102.140 -p 10050 -k "system.cpu.load[all,avg1]"
zabbix_get [18708]: Check access restrictions in Zabbix agent configuration

zabbix-agent上授权zabbix-server可以过来拉数据

[root@zabbix-agentd-1 zabbix]# pwd
/etc/zabbix

[root@zabbix-agentd-1 zabbix]# vim zabbix_agentd.conf 
##### Passive checks related

### Option: Server
#       List of comma delimited IP addresses, optionally in CIDR notation, or DNS names of Zabbix servers and Zabbix proxies.
#       Incoming connections will be accepted only from the hosts listed here.
#       If IPv6 support is enabled then '127.0.0.1', '::127.0.0.1', '::ffff:127.0.0.1' are treated equally
#       and '::/0' will allow any IPv4 or IPv6 address.
#       '0.0.0.0/0' can be used to allow any IPv4 address.
#       Example: Server=127.0.0.1,192.168.1.0/24,::1,2001:db8::/32,zabbix.example.com
#
# Mandatory: yes, if StartAgents is not explicitly set to 0
# Default:
# Server=

Server=127.0.0.1,192.168.102.135

##### Active checks related

### Option: ServerActive
#       Zabbix server/proxy address to get active checks from.
#       Server/proxy address is IP address or DNS name and optional port separated by colon.
#       Multiple Zabbix servers and Zabbix proxies can be specified, separated by comma.
#       More than one Zabbix proxy should not be specified from each Zabbix server.
#       If Zabbix proxy is specified then Zabbix server for that proxy should not be specified.
#       Multiple comma-delimited addresses can be provided to use several independent Zabbix servers in parallel. Spaces are allowed.
#       If port is not specified, default port is used.
#       IPv6 addresses must be enclosed in square brackets if port for that host is specified.
#       If port is not specified, square brackets for IPv6 addresses are optional.
#       If this parameter is not specified, active checks are disabled.
#       Example: ServerActive=127.0.0.1:20051,zabbix.example.com,[::1]:30051,::1,[12fc::1]
#
# Mandatory: no
# Default:
# ServerActive=

ServerActive=127.0.0.1,192.168.102.135  #允许的ip地址，过来拿数据

[root@zabbix-agentd-1 zabbix]# service zabbix-agent restart
Redirecting to /bin/systemctl restart zabbix-agent.service

在被监控主机上关闭防火墙和selinux

[root@centos-LB-1 zabbix]# service firewalld stop
Redirecting to /bin/systemctl stop firewalld.service

[root@centos-LB-1 zabbix]# getenforce 
Disabled

在zabbix server上执行

[root@zabbix ~]# zabbix_get -s 192.168.102.140 -p 10050 -k "system.cpu.load[all,avg1]"
0.000000

添加被监控主机

步骤

    点配置--》主机--》创建主机

主机：  被zabbix-server监控的主机 。

模板： template  里面已经集合了很多的好用的应用集，专门针对web的模板，MySQL的模板。
cpu，disk（filesystem），memory，interface traffic等。

应用集： 各种各样的应用的集合，zabbix对应用进行分类： web，database，ssh，traffic，cpu，memory，disk等，各种监控项的集合。

监控项： 被监控的某个项目，例如cpu的使用率， cpu的负载等，网络的流量  针对某个具体的功能进行的监控。

监控项--》应用集---》模板： 针对某类型的应用配置好了很多的应用集，应用集有很多的监控项。

使用模板的好处就是简单，快速的添加监控项

常见的key

net.if.out["ens33"]
net.if.in["ens33"]
vfs.fs.size[/,used]
system.cpu.util[,system]
system.cpu.util[,user]
vm.memory.size[pavailable]
