Zabbix Web 场景变量随机数或其他函数
Zabbix Web scenarios variables random number or other function
我需要 post 具有随机数值的变量。我如何在网络场景中生成随机变量?我可以 运行 一些脚本或宏来为场景或步骤生成随机值吗?
没有本地方法可以做到这一点,正如您猜想的那样,您可以使用宏和自定义脚本使其工作。
您可以定义一个 {$RANDOM}
主机宏,并在 Web 场景步骤中将其用作 post 字段 value
。
然后您必须使用 crontabbed 脚本定期更改它,python 示例如下:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""
Set a random macro to a value.
Provide user from the commandline or from Env var support:
# export ZABBIX_SERVER='https://your_zabbix_host/zabbix/'
# export ZABBIX_USERNAME='admin'
# export ZABBIX_PASSWORD='secretPassword'
$ ./setRandomMacro.py -u admin -p zabbix -Z http://yourzabbix -H yourHost -M '{$RANDOM}'

Host yourHost (Id: ----)
{$RANDOM}: current value "17" -> new value "356"
$ ./setRandomMacro.py -u admin -p zabbix -Z http://yourzabbix -H yourHost -M '{$RANDOM}'
