宏函数提供自定义 macro 值的功能(例如,缩短或提取特定的子字符串)使它们更容易处理。
所有在这里列出的函数都支持所有类型的宏:
这些宏函数可以在支持上述宏的所有位置使用。 除非明确指定只能使用宏(例如,在配置 主机宏 或低级别自动发现规则 过滤器时),否则适用此规则。
这些函数列出时未提供额外信息。点击函数以查看完整详情。
函数 | 描述 |
---|---|
fmtnum | 数字格式化,用于控制小数点后打印的位数。 |
fmttime | 时间格式化。 |
iregsub | 使用不区分大小写的正则表达式匹配提取子字符串。 |
regsub | 使用区分大小写的正则表达式匹配提取子字符串。 |
宏函数的语法如下:
可选的函数参数用 < > 表示。
Encoding a macro value into Base64 format. This function is supported since Zabbix 7.0.4.
用于控制小数点后打印的数字位数。
参数:
示例:
宏函数 | 输入值 | 输出值 |
---|---|---|
{{ITEM.VALUE}.fmtnum(2)} |
24.3413523 |
24.34 |
{{ITEM.VALUE}.fmtnum(0)} |
24.3413523 |
24 |
时间格式化函数。
注意,此函数可用于解析以下时间格式之一的宏:
hh:mm:ss
yyyy-mm-ddThh:mm:ss[tz]
(ISO8601 标准)参数:
strftime
函数格式兼容;-<N><time_unit>
或 +<N><time_unit>
开头,其中:N
- 要添加或减去的时间单位数量;time_unit
- h (小时), d (天), w (周), M (月) or y (年)。注释:
time_shift
参数支持多步时间操作,可以包括/<time_unit>
用于将时间移动到时间单位的开始处 (/d
- 午夜, /w
- 上周的第一天(星期一), /M
- 上个月的第一天等)。 示例:-1w
- 后退7天; -1w/w
- 上周一; -1w/w+1d
- 上周二。-1M/d+1h/w
将解析为 ((-1M/d)+1h)/w

---|---|---|
{{TIME}.fmttime(%B)} |
12:36:01 |
October |
{{TIME}.fmttime(%d %B,-1M/M)} |
