Prometheus是一个开源系统监控和警报系统。
holt_winters(v range-vector, sf scalar, tf scalar) produces a smoothed value for time series based on the range in v. The lower the smoothing factor sf, the more importance is given to old data. The higher the trend factor tf, the more trends in the data is considered. Both sf and tf must be between 0 and 1.
holt_winters should only be used with gauges.
错误:sum(http_requests_total{method="GET"} offset 5m} // GOOD
正确:sum(http_requests_total{method="GET"} offset 5m) // GOOD
histogram and summaries不理解
histogram_quantile()函数不理解
分位数不理解
文章中发现很多错误的翻译和文字不对的情况,部分字段有直接谷歌翻译的感觉,希望能优化下。
可以考虑对接 Gitbook 阅读更方便
label_replace
函数,输入:瞬时向量,输出:key: value = 度量指标: 值(要替换的内容:首先 ,针对src_label标签,对该标签值进行regex正则表达式匹配。如果不能匹配的度量指标,则不发生任何改变;否则,如果匹配,则把dst_label标签的标签纸替换为replacement
例子:度量指标样本数据:http_requests_total{code="400",handler="query",instance="120.77.65.193:9090",job="prometheus",method="get"} 9
label_replace函数执行
label_replace(http_requests_total{code="400",handler="query",instance="120.77.65.193:9090",job="prometheus",method="get"}, "instance", "hello,world", "method", "ge.*")
显示结果:
http_requests_total{code="400",handler="query",instance="hello,world",job="prometheus",method="get"} 9
!=: 给定的标签值不符合正则表达式需要
符号错了,需要改成
!~: 给定的标签值不符合正则表达式需要
为什么group取了中文名字就无法启动?写出英文就可以启动,怎么办?
