简介

用于从系统和服务收集指标。Metricbeat和Filebeat一样，是一个轻量级的采集器，提供多种内部模块，这些模块可从多项服务.不但可以监控服务器的性能指标，还可以监控运行在服务区之上的应用信息(诸如Apache、MongoDB、MySQL、Ngnix、Redis、Zookeeper、System)。

将 Metricbeat 部署到您的所有 Linux、Windows 和 Mac 主机，并将它连接到 Elasticsearch 就大功告成了：您可以获取系统级的 CPU 使用率、内存、文件系统、磁盘 IO 和网络 IO 统计数据，还可针对系统上的每个进程获得与 top 命令类似的统计数据。

部署ElasticSearch和Kibana

ElasticSearch和Kibana已经搭建好了 信息如下:

部署文档参考: 

ElasticSearch: 10.208.1.11:29200
Kibana: 10.208.1.11:5601

部署Metricbeat

官方文档: https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-getting-started.html

下载安装

# wget https://artifacts.elastic.co/downloads/beats/metricbeat/metricbeat-6.4.0-linux-x86_64.tar.gz
# tar zxvf metricbeat-6.4.0-linux-x86_64.tar.gz 
# mv metricbeat-6.4.0-linux-x86_64 /data/app/metricbeat
# cd /data/app/metricbeat/

启用模块和配置输出

# sed -i 's/#setup.dashboards.enabled: false/setup.dashboards.enabled: true/g' metricbeat.yml 
# grep setup.dashboards.enabled metricbeat.yml    
setup.dashboards.enabled: true

# 启用nginx,redis模块
# ./metricbeat modules enable nginx redis system
Enabled nginx
Enabled redis
Enabled system

# 配置输出到Elasticsearch
# vim metricbeat.yml 
output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["10.208.1.11:29200"]
  
# 配置Kibana端点
# vim metricbeat.yml
setup.kibana:
  host: "10.208.1.11:5601"
