我是靠谱客的博主清秀大树，最近开发中收集的这篇文章主要介绍prometheus api一、文档资料二、访问接口三、常地址，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

如何配置prometheus的Java客户端 https://blog.csdn.net/frog4/article/details/84579165

一、文档资料

1.prometheus官方http API

https://prometheus.io/docs/prometheus/1.8/querying/api/ 可以根据使用的版本选择API
在这里插入图片描述

2.prometheus-operator

k8s集群使用prometheus-operator做监控

文档 https://github.com/coreos/prometheus-operator/blob/master/Documentation/api.md#prometheusspec

二、访问接口

http://192.168.14.176 为k8s master节点,根据实际部署替换

prometheus-operator

prometheus-operator部署prometheus集群监控

[root@docker176 ~]# kubectl -n monitoring get pod,svc

使用grafana请求

http://192.168.14.176:30902/api/datasources/proxy/1/api/v1/query_range?query=((sum(node_memory_MemTotal)%20-%20sum(node_memory_MemFree)%20-%20sum(node_memory_Buffers)%20-%20sum(node_memory_Cached))%20%2F%20sum(node_memory_MemTotal))%20*%20100&start=1550732384&end=1550810623&step=1800

直接请求prometheus

http://192.168.14.176:30900/api/v1/query_range?query=((sum(node_memory_MemTotal)%20-%20sum(node_memory_MemFree)%20-%20sum(node_memory_Buffers)%20-%20sum(node_memory_Cached))%20%2F%20sum(node_memory_MemTotal))%20*%20100&start=1550732384&end=1550810623&step=1800

上面面两个请求的结果相同
prometheus http://192.168.14.176:30900/api/v1/query_range
grafana http://192.168.14.176:30902/api/datasources/proxy/1/api/v1/query_range grafana通过k8s的datasources/proxy请求到prometheus中
