Due to network problems, Zabbix with the Web module can not use, background research and Development 2b, always update the formal environment installation package, leading to problems, always give them to wipe the buttocks, said this matter, they do not cooperate, now the problem, very cool, this pot I say no back, find the Pycurl This module write a monitor.

Second, configure the Zabbix to customize the monitoring
This is relatively flexible, you can find a machine dedicated to monitoring, only need to configure the following on this machine to monitor multiple URLs.
A template can be configured in the Zabbix interface to hang it on the machine.
1. Write the code to the following directory and add the executable permission
| 1234 |
[[email protected] scripts]# pwd/etc/zabbix/scripts[[email protected] scripts]# vim web_monitor.py [[email protected] scripts]# chmod +x web_monitor.py |
2, Configuration zabbix_agentd.conf
| 12 |
[[email protected] scripts]# cat /etc/zabbix_agentd.confUserParameter=web[*],/etc/zabbix/scripts/web_monitor.py $1 $2 |
3. Restart Zabbix-agentd
| 1 |
[[email protected] scripts]# service zabbix-agentd restart |
Third, configure Zabbix monitoring
Directly, the subsequent addition of the free play, a lot of return value can be out of the picture, can do trigger alarm and so on. Not much to describe.
