For example, when I needed to match multiple metrics using the common labels, I quickly found myself reading the code implementing binary operations on vectors. Without a solid understanding of the matching rules, I constantly stumbled upon various query execution errors, such as complaints about ...
依托alibaba-cloud-metrics-adapter组件,负责转换Prometheus监控指标为HPA可消费的Kubernetes聚合指标。更多信息,请参见Autoscaling on multiple metrics and custom metrics。 配置并部署HPA,根据上一步的指标进行弹性扩缩。 指标类型根据场景分为两种: Custom Metric:根据与要进行扩缩的Kubernetes目标对象(例如Pod)相关的指...
Flexible and powerful query statement (PromQL): One query statement supports addition, multiplication, and connection for multiple metrics. Easy to manage: The Prometheus server is a separate binary file that can work locally. It does not depend on distributed storage. ...

metric有Counter、Gauge、Histogram和Summary四种类型。在指标生成端,也就是应用程序中,调用prometheus的sdk创建metrics的时候,必须要明确是哪一种类型的metrics。 见:使用Prometheus SDK输出Prometheus格式的Metrics Counter是累计数值,只能增加或者在重启时被归零。
The features that distinguish Prometheus from other metrics and monitoring systems are: A multi-dimensional data model (time series defined by metric name and set of key/value dimensions) PromQL, a powerful and flexible query language to leverage this dimensionality No dependency on distributed storage...
For instance,varnish_main_client_req{namespace=~".*3.*",namespace!~".*env4.*"}will return allvarnish_main_client_reqmetrics with a 3 in their namespace that don’t also containenv4. Range Selectors By appending arange durationto a query, we get multiple values for each timestamp. Thi...
Throughout the story, we’ll use Prometheus Adapter as a known solution to collect the Kubeless function metrics and auto-scale the functions. 在整个故事中,我们将使用Prometheus Adapter作为已知的解决方案来收集无Kube函数度量并自动缩放函数。
在指标生成端,也就是应用程序中,调用prometheus的sdk创建metrics的时候,必须要明确是哪一种类型的metrics。 见:使用Prometheus SDK输出Prometheus格式的Metrics Counter是累计数值,只能增加或者在重启时被归零。 Gauge是瞬时值。 Histogram(直方图)对采集的指标进行分组计数,会生成多个指标,分别带有后缀...
