Prometheus 简介 Prometheus 是SoundCloud开源的一款开源软件。它的实现参考了Google内部的监控实现，与源自Google的Kubernetes结合起来非常合适。另外相比influxdb的方案，性能更加突出，而且还内置了报警功能。它针对大规模的集群环境设计了拉取式的数据采集方式，你只需要在你的应用里面实现一个 metrics 接口，然后把这个接口告诉 Prometheus 就可以完成数据采集了。安装Prometheus 首先我们使用 ConfigMap 的形式来设置 Prometheus 的配置文件，如下 apiVersion: v1 kind: ConfigMap metadata: name: prometheus-configuration labels: app.kubernetes.io/name: prometheus app.kubernetes.io/part-of: ingress-nginx name: prometheus-configuration namespace: ingress-nginx data: prometheus.yml: |- global: scrape_interval: 10s scrape_configs: - job_name: 'ingress-nginx-endpoints'

We investigated pulling out the address of each case label and storing it in the stream of byte-code itself, rather than the instruction ID that we usually switch on. If we do that, we can skip the jump table, and directly jump to the location of code of
