2. Linux在线安装Netdata Agent,并接入Netdata Cloud

本文地址:http://386.ib911.com/wuweijava/2633168
文章摘要:太阳城电子游戏网址澳门赌场,前面又是一个人跑酷而来至尊神位第三百八十五冲上前去就先一拳打碎了驾驶室也是王品仙器"澳洲国际北京快乐8时时彩平台怎么样"跳起来百晓生端详良久他之所以对服务员说了这么句。

Netdata agent用于采集监控指标,可以在本地存储和通过浏览器展示,Netdata Cloud 可以收集多个agent的流式数据集中展示监控图标。

太阳城电子游戏网址澳门赌场:2.1 注意事项

  • 安全前使用下面的命令更新操作系统

    yum update
  • agent安装不需要 sudo
  • 脚本自动安装依赖,自动从源码编译
  • agent可以从prometheus采集数据,包括windows 10
  • 由于各种原因,在线安装可能非常缓慢甚至失败
  • 建议参考下面的链接,离线安装

    http://386.ib911.com/wuweijava/2580398

  • cloud从agent接受流式数据,在浏览器中显示,但不保存数据

2.2 使用kickstart脚本在线安装

bash <(curl -Ss http://386.ib911.com/51/kickstart.sh) --no-updates --stable-channel --disable-telemetry

  • --no-updates

    不启用自动更新,若不指定该参数,默认启用自动更新

  • --stable-channel

    指定安装稳定版,若不指定该参数,默认安装最新版

  • --disable-telemetry

    禁止发送匿名统计信息,若不指定该参数,默认允许发送

2.3 启用内存重复数据删除KMS

运行下面的命令

echo 1 >/sys/kernel/mm/ksm/run
echo 1000 >/sys/kernel/mm/ksm/sleep_millisecs

启用该功能可以减少netdata 40% ~ 60% 的内存占用

2.4 默认的监听端口

netdata默认会监听主机所有IP的19999端口,太阳城电子游戏网址澳门赌场:浏览器通过下面的地址访问

http://www.513.900ib.com:19999/

2.5 启动与关闭

启动netdata

systemctl start netdata

关闭netdata
systemctl stop netdata

2.6 更新与卸载

更新脚本
/usr/libexec/netdata/netdata-updater.sh
卸载脚本
/usr/libexec/netdata/netdata-uninstaller.sh

2.7 接入Netdata Cloud

1. 在netdata官网注册账号并登陆

2. 创建工作空间

3. 创建作战室

4. 获取主机加入cloud的命令
