metrics 客户端
数据采集使用go-metrics
传输使用UDP, 仿StatsD上传采集数据, InfluxDB进行数据存储, Grafana进行展示。
实现github 地址
https://github.com/solate/metrics
该地址有已经改好的配置文件可以直接使用。
使用的all-in-one :
git docker-statsd-influxdb-grafana
docker hub 地址
数据封装
//挂载配置文件，已修改statsd模版 docker run --ulimit nofile=66000:66000 -v /root/telegraf.conf:/etc/telegraf/telegraf.conf -d --name docker-statsd-influxdb-grafana -p 3003:3003 -p 3004:8888 -p 8086:8086 -p 8125:8125/udp samuelebistoletti/docker-statsd-influxdb-grafana:latest
register
register 使用的name 必须是不同的
telegraf 配置修改
将 [[inputs.statsd]] 部分配置打开, 修改templates为:
templates = [ "* measurement.measurement.field" ]
表示传值prefix.name.field 最好表示为 prefix_name field
代码实现
package client

"bufio"
"bytes"
"github.com/rcrowley/go-metrics"
"log"
"net"
"strconv"
"strings"
"time"

// https://en.wikipedia.org/wiki/User_Datagram_Protocol#Packet_structure
UDP_MAX_PACKET_SIZE int = 64 * 1024
)
// Config provides a container with configuration parameters for
// the StatsD exporter
type Config struct {
Network string // Network: tcp, udp.
Addr string // Network address to connect to | 地址
Registry metrics.Registry // Registry to be exported | metrics注册
FlushInterval time.Duration // Flush interval | 刷新间隔时间
Prefix string // Prefix to be prepended to metric names | 前缀名字
Rate float32 // Rate
Tags string // tag //TODO
conn net.Conn
}
