riemann的安裝和使用

Riemann monitors distributed systems.

具體介紹就很少說了,一個分佈式的監控系統。能夠接收各類event上報,而後經過強大的腳本和插件,展現曲線,柱狀,餅圖等來對系統進行監控。html

1、riemann安裝java

這裏主要說ubuntu的安裝:

首先,須要java、ruby環境:
sudo apt-get -y install default-jre ruby-dev build-essential

  而後下載riemann的包:python

wget https://aphyr.com/riemann/riemann_0.2.8_all.deb
而後直接安裝就OK了:
sudo dpkg -i riemann_0.2.8_all.deb

採用命令就能夠啓動服務了:
 sudo service riemann start
 

2、riemann配置git

配置文件在github

/etc/riemann/riemann.configweb

默認配置以下django

; -*- mode: clojure; -*-
; vim: filetype=clojure

(logging/init {:file "/var/log/riemann/riemann.log"})

; Listen on the local interface over TCP (5555), UDP (5555), and websockets
; (5556)
(let [host "127.0.0.1"]
(tcp-server {:host host})
(udp-server {:host host})
(ws-server  {:host host}))

; Expire old events from the index every 5 seconds.
(periodically-expire 5)

(let [index (index)]
; Inbound events will be passed to these streams:
(streams
  (default :ttl 60
    ; Index all events immediately.
    index

    ; Log expired events.
    (expired
      (fn [event] (info "expired" event))))))

 

 

可使用go的client進行event的發送:ubuntu

package main

import (
    "github.com/bigdatadev/goryman"
    //"fmt"
    "time"
    "math/rand"
)

func main(){
c := goryman.NewGorymanClient("localhost:5555")
err := c.Connect()
if err != nil {
    panic(err)
}

defer c.Close()

for {
rd := rand.New(rand.NewSource(time.Now().UnixNano()))

err = c.SendEvent(&goryman.Event{
    Host : "box1",
    Service: "foo",
    Metric:  rd.Intn(1000),
    Tags: []string{"meter","dev"},
})
if err != nil {
    panic(err)
}

rd = rand.New(rand.NewSource(time.Now().UnixNano()))

err = c.SendEvent(&goryman.Event{
    Host : "box2",
    Service: "bar",
    Metric:  rd.Intn(1000),
    Tags: []string{"meter","dev"},
})
if err != nil {
    panic(err)
}
}
}

 

 

 

3、把riemann數據使用graphite來進行畫圖vim

因爲riemann自己提供的數據圖形化比較難弄,可是它能夠方便的只想graphite進行處理。ruby

因此,咱們裝一下graphite。

#安裝啓動graphite
pip install carbonpip install whisperpip install graphite-web
pip install Django
pip install django-tagging

#默認安裝路徑在 /opt/graphite/目錄下

#初始化配置 PYTHONPATH
=`pwd`/webapp:`pwd`/whisper python ./webapp/graphite/manage.py syncdbecho DEBUG = True > webapp/graphite/local_settings.py

#啓動web服務,web訪問界面 PYTHONPATH
=`pwd`/whisper ./bin/run-graphite-devel-server.py --libs=`pwd`/webapp/ /opt/graphite/

#啓動接收數據的後臺進程
puchd config cp carbon/conf/carbon.conf.example carbon/conf/carbon.confPYTHONPATH=`pwd`/whisper ./carbon/bin/carbon-cache.py --debug start

在riemann的配置中增長一行:

 

; -*- mode: clojure; -*-
; vim: filetype=clojure

(logging/init {:file "/var/log/riemann/riemann.log"})

; Listen on the local interface over TCP (5555), UDP (5555), and websockets
; (5556)
(let [host "127.0.0.1"]
(tcp-server {:host host})
(udp-server {:host host})
(ws-server  {:host host}))

; Expire old events from the index every 5 seconds.
(periodically-expire 5)

(let [index (index)]
; Inbound events will be passed to these streams:
(streams
  (default :ttl 60
    ; Index all events immediately.
    index

    ; Log expired events.
    (expired
      (fn [event] (info "expired" event))))))

#定義graph繪圖的host,這裏是部署在一臺機器上面的
(def graph (graphite {:host "localhost"}))

;全部的event數據都發給graph進行繪圖

(streams  graph)

 

而後啓動go的test程序進行發送數據,就能在graphite上面看到數據了:

 

 

總結:

riemann很是靈活,但靈活的同時是學習成本的增長。你必需要學會他的配置,並且要熟悉對應的配置語言的語法和函數(固然學會以後,就很是流弊了)。

具體能夠參考它官網的howto介紹。 這裏就淺嘗輒止了,後面項目有須要再好好研究。
