prometheus中pushgateway方式收集数据 _gateway

一身转战三千里，一剑曾百万师。这篇文章主要讲述prometheus中pushgateway方式收集数据相关的知识，希望能为你提供帮助。
一.pushGateway搭建

一.搭建pushgateway docker pull prom/pushgateway docker run -d --name=pg -p 9091:9091 prom/pushgateway 或者 docker run -d--name=pg10-p 9091:9091 prom/pushgateway"--persistence.file=pushgateway.data--persistence.interval=3" 持久化保存数据 #访问方式: http://xxx.195.185.78:9091/# 二.配置prometheus 2.1修改配置 - job_name: pushgateway static_configs: - target: [10.206.16.14:9091] label: instance: pushgateway 2.2 使配置生效(使用k8s搭建) kubectlapply -f prometheus-configmap.yaml curl -X POST 10.1.192.105:9090/-/reload 2.3 查看是否在prometheus生效 http://xxx.195.185.78:30089/targets #参考资料 https://www.cnblogs.com/xiao987334176/p/9933963.html https://songjiayang.gitbooks.io/prometheus/content/pushgateway/how.html

二.shell数据管理 2.1操作

#2.1 shell形式添加数据,主要是添加一个job echo "some_metric 3.14" | curl --data-binary @- http://127.0.0.1:9091/metrics/job/test_job #2.2在某一个job下添加instance cat < < EOF | curl --data-binary @- http://127.0.0.1:9091/metrics/job/test_job/instance/some_instance # TYPE some_metric counter some_metriclabel="val1" 999 # TYPE another_metric gauge # HELP another_metric Just an example. another_metric 2398.283 EOF #2.3以文件形式发送到pushgateway vim pgdata.txt # TYPE http_request_total counter # HELP http_request_total get interface request count with different code. http_request_totalcode="200",interface="/v1/save" 276 http_request_totalcode="404",interface="/v1/delete" 0 http_request_totalcode="500",interface="/v1/save" 1 http_request_timecode="200",interface="/v1/core" 0.122curl -XPOST --data-binary @pgdata.txt http://127.0.0.1:9091/metrics/job/app/instance/app-172.30.0.0#2.4常用操作 #删除某个组下的所有数据 curl -X DELETE http://127.0.0.1:9091/metrics/job/test_job #删除某个组下某个实例的所有数据： curl -X DELETE http://127.0.0.1:9091/metrics/job/test_job/instance/some_instance

三. python数据管理 3.1 安装模块

#1.提前安装py模块 pip install flask pip install prometheus_client

3.2 prometheus提供4种不通同类型metrics

Counter, Gauge, Summar和Histogram

3.3 使用gauge方式写入数据

#!/usr/bin/python # -*- coding: UTF-8 -*- from prometheus_client import CollectorRegistry, Gauge, push_to_gateway if __name__ == __main__: registry = CollectorRegistry() labels = [req_status, req_method, req_url] g_one = Gauge(requests_total, url请求次数, labels, registry=registry) g_two = Gauge(avg_response_time_seconds, 1分钟内的URL平均响应时间, labels, registry=registry) g_one.labels(200,GET, /test/url).set(1) #set设定值 g_two.labels(200,GET, /test/api/url/).set(10) #set设定值 push_to_gateway(http://127.0.0.1:9091, job=SampleURLMetrics, registry=registry)

四.go数据管理

package main import ( "fmt" "github.com/prometheus/client_golang/prometheus" "github.com/prometheus/client_golang/prometheus/push" ) func main() ExamplePusher_Push()func ExamplePusher_Push() completionTime := prometheus.NewGauge(prometheus.GaugeOpts Name: "db_backup_last_completion_timestamp_seconds", Help: "The timestamp of the last successful completion of a DB backup.", ) completionTime.SetToCurrentTime() if err := push.New("http://127.0.0.1:9091", "db_backup").// push.New("pushgateway地址", "job名称") Collector(completionTime).// Collector(completionTime) 给指标赋值 Grouping("db", "customers").Grouping("instance", "1.1.1.1").// 给指标添加标签，可以添加多个 Push(); err != nil fmt.Println("Could not push completion time to Pushgateway:", err)
