INFO Info metrics are used to expose textual information which SHOULD NOT change during process lifetime. Common examples are an application's version, revision control commit, and the version of a compiler. Info指标用于暴露在流程生命周期内不应更改的文本信息。 常见例子是应用程序的版本、版本控制提交...
因为使用 irate 函数时,速率的简短变化会重置FOR语句,形成的图形有很多波峰,难以阅读。 [info] 注意 当将irate()函数与聚合运算符(例如sum())或随时间聚合的函数(任何以_over_time结尾的函数)一起使用时,必须先执行 irate 函数,然后再进行聚合操作, 否则当采样目标重新启动时 irate() 无法检测到计数器是否被重...

这段代码的前半部分是针对target_info,由于我们的registry在初始化的时候没有传递target_info参数,默认为None,所以前边这部分代码可以忽略。后面的核心代码可以看到就是要把注册的collector拿出来一个一个去调用collect()方法,从而获取到对应collector的metrics。
INFO指标用于暴露在流程生命周期内不应更改的文本信息。Histogram用于统计离散事件的分布，如HTTP请求的延迟或函数运行时间。GAUGE_HISTOGRAM测量当前分布，如队列中等待时间的分布或请求大小的分布。SUMMARY指标也是用于测量离散事件的分布，引入了分位数的概念。Collector的实现分为SimpleCollector，内置Collector的...
