Zabbix Add Custom item, trigger, graphic, and execute remote command

#前言:
Rough look is very complex, in fact, follow the steps to do a bit, very simple!

#意图:
When the agentd-side monitoring service is down, it attempts to restart it.

#环境:

1, VMware12, CentOS 7.1, Zabbix 2.4.6
2. Zabbix Server ip:10.10.100.104
3, Zabbix Agentd ip:10.10.100.105
4. The server side and the Agentd end are respectively turned off SELinux and FIREWALLD:

4.1, vim/etc/selinux/conf
Selinux=disabled
4.2. Service Firewalld Stop
Chkconfig Firewalld off
4.3, reboot

#流程:

1, operation in: Agentd end

#自定义监控脚本

[email protected] libexec]# cat httpd_service.sh #!/bin/bash proc=$ (netstat-lnutp | grep httpd | grep-v grep | gawk ' {print $7} ' | Gawk ' BEGIN {fs= '/'}{print $} ' | WC-L) #获取httpd proces information if ["$proc" = "] then echo 0 #如果没有httpd proces information, echo 0 else echo $proc #如果 With httpd proces information, echo counts the number of rows fi

Note: If your script returns only a fixed value, no graphics will be generated.

#zabbix_agentd. conf configuration

Vim/usr/local/zabbix/etc/zabbix_agentd.conf

Unsafeuserparameters=1 #允许使用自定义item userparameter=httpd_monitor,/usr/local/zabbix/libexec/httpd_service.sh # Userparameter=item name, script path Allowroot=1 #测试时使用root账号的话, and allow root server=10.10.100.104 to be used #server端ip Enableremotecommand S=1 #允许执行远程命令 Logfile=/tmp/zabbix_agentd.log #日志路径

Warning:
To use a remote command in the "Configure" action, "serveractive" must not be turned on, and I have stumbled here.

2, operation in: Server side

#添加自定义item, triggers, graphics steps:

1. Add Host

Note:
1. Add multiple triggers to the class and choose a different "severity" to tell you what level of "problem" is occurring.
2. Expression description, {host: project. function}= value (function is System defined)

5. Create a graphic

At this point, the custom item, trigger, and graphics are added.

3, operation in: Server side

#配置动作

1, configuration "action" create action "

1.1 Action, fill in "name" can

1.2 Items, calculation method, select "and" (see actual need) "new trigger conditions, host = XXX (select the above steps to create the host)" Add

1.3 operation, "new" "Stage" (from ...) To, how many times, step duration), operation type Select Remote command
1.3.1 Target list, "new" target Select "Host", (select the host created by the above steps) add

1.4 Type, "Custom Script", executed in "Zabbix agent"
1.5 commands, see need, I enter "service httpd restart" here
1.6 pieces, see need

At this point, the "action" is added.

4. Testing

1. Perform service httpd stop on AGENTD side
2, observe Zabbix server, prompt problem, one will successfully perform remote command restore normal state.

650) this.width=650; "title=" Monitor Graph.jpg "src=" http://s4.51cto.com/wyfs02/M01/76/54/ Wkiom1zpnipc1uj0aaz313ld2qy877.jpg "alt=" Wkiom1zpnipc1uj0aaz313ld2qy877.jpg "/>
