的监控系统，比如阿里云不但 有云监控，还有 ARMS，还有 SLS。 大部分公司都不会只使用一套监控系统，网络设备的监控可能采用的 Zabbix，Kubernetes 的监控可能 用的 Prometheus（Kubernetes 可能有多套，以至于 Prometheus 可能有多套）或者 Nightingale， 日志的监控可能用的 Elastalert，如果上云了，可能还会有多套不同的云监控（尤其是多云场景下）。

记录，所以高基数的一侧是左侧，故而使用 group_left。 另外举一个例子，说明 group_left group_right 的一个常见用法，比如我们使用 kube-state- metrics 来采集 Kubernetes 各个对象的指标数据，其中针对 pod 有个指标是 kube_pod_labels，会把 pod 的一些信息放到这个指标的标签里，指标值是1，相当于一个元信 息，比如： kube_pod_labels{

OpenMetrics Outro Problem statement After Prometheus Prometheus has become a de-facto standard in cloud-native metric monitoring Ease of exposing data has lead to an explosion in compatible metrics endpoints Introduction Quick intro OpenMetrics Outro Problem statement Goldrush So about fragmentation... Cloud native is in the buzz phase Explosive growth always equals goldrush and stake claiming, aka fragmentation Quick intro OpenMetrics Outro Plans Beyond cloud OpenMetrics is intended to go beyond ”just” cloud-native fields Want to get more traditional projects and vendors on board Arista already on board Vertiv
