zabbix-server新增zabbix-agent

 

zabbix监控系统搭建好了之后,就需要为各种角色host加入进来,现在新增一台zabbix-agent:

1.在172.16.23.128上安装zabbix-agent,zabbix-server:172.16.23.131

?

1 2 3 4 5

# rpm -Uvh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm # cd /etc/yum.repos.d/ # mv epel.repo epel.repo.bak # yum install zabbix zabbix-agent -y # mv epel.repo.bak epel.repo

 安装完成agent端程序之后,现在做一些简单配置:

?

1 2 3

# sed -i 's/Server=127.0.0.1/Server=172.16.23.131/g' /etc/zabbix/zabbix_agentd.conf # sed -i 's/ServerActive=127.0.0.1/ServerActive=172.16.23.131/g' /etc/zabbix/zabbix_agentd.conf Hostname=172.16.23.128

 然后开启服务,并检查日志是否报错:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

# systemctl start zabbix-agent # systemctl status zabbix-agent # tail -f /var/log/zabbix/zabbix_agentd.log [root@master zabbix_agentd.d]# tail -f /var/log/zabbix/zabbix_agentd.log   7681:20181209:123239.539 IPv6 support:          YES   7681:20181209:123239.539 TLS support:           YES   7681:20181209:123239.539 **************************   7681:20181209:123239.539 using configuration file: /etc/zabbix/zabbix_agentd.conf   7681:20181209:123239.540 agent #0 started [main process]   7682:20181209:123239.540 agent #1 started [collector]   7683:20181209:123239.540 agent #2 started [listener #1]   7684:20181209:123239.541 agent #3 started [listener #2]   7686:20181209:123239.542 agent #5 started [active checks #1]   7685:20181209:123239.543 agent #4 started [listener #3]

 然后配置zabbix的web页面:

注意:这里的hostname一定要和zabbix-agent端配置文件的hostname一致,不然会报错如下:

?

1 2 3 4 5 6 7 8 9 10 11 12

[root@master zabbix_agentd.d]# tail -f /var/log/zabbix/zabbix_agentd.log   7644:20181209:122919.996 TLS support:           YES   7644:20181209:122919.996 **************************   7644:20181209:122919.996 using configuration file: /etc/zabbix/zabbix_agentd.conf   7644:20181209:122919.997 agent #0 started [main process]   7645:20181209:122919.997 agent #1 started [collector]   7646:20181209:122919.998 agent #2 started [listener #1]   7648:20181209:122919.999 agent #4 started [listener #3]   7647:20181209:122919.999 agent #3 started [listener #2]   7649:20181209:122920.000 agent #5 started [active checks #1]   7649:20181209:122920.007 no active checks on server [172.16.23.131:10051]: host [master] not found   7649:20181209:123120.077 no active checks on server [172.16.23.131:10051]: host [master] not found

 当只添加了host而没有添加template,那么日志并不会报错,但是web页面那里的agent不会变绿:

上面是添加template之后的,所以agent变为了绿色

 zabbix-agent:172.16.23.128    zabbix-server:172.16.23.131

现在在agent端配置自定义item:

/etc/zabbix/zabbix_agentd.d/userparameter_script.conf

?

1 2	[root@master zabbix_agentd.d]# cat userparameter_script.conf UserParameter=getupload,/etc/zabbix/getupload.py

 配置文件确保这里是打开的:Include=/etc/zabbix/zabbix_agentd.d/*.conf,/etc/zabbix/getupload.py该脚本必须有执行权限

?

1 2 3 4 5 6 7 8 9 10

[root@master zabbix_agentd.d]# cat /etc/zabbix/getupload.py #!/usr/bin/env python def getload():     with open("/proc/loadavg", "r") as f:         con2 = f.read().split()     f.close()     return con2     print(getload()[0])

 agent配置完成后重启zabbix-agent服务:systemctl restart zabbix-agent

然后在zabbix-server端手动获取该值:

?

1 2	[root@zabbix-server zabbix_agentd.d]# zabbix_get -s 172.16.23.128  -k getupload 0.00

 上面-s 后面接上zabbix-agent的ip,如果agent在server上就和server ip一致,-k后面接命名的item
