最近同事推薦了一款很炫炮的監控軟體，畫面很漂亮很酷
二話不說就馬上上網找步驟安裝起來,但是因為XenServer
安裝比較麻煩需要先改repo才能進行 yum install
這邊我會再寫一篇修改for XenServer 7.x版本的repo檔
下圖是Netdata 監控XenServer 所看到的DashBoard
安裝步驟如下 :
Step 1: Update the system
For security purposes, update the system to the latest stable status using YUM:
sudo yum update -y && sudo reboot
After the reboot finishes, log in with the same sudo user.
Step 2: Install dependencies
In order to install Netdata, you need to install the dependencies below:
sudo yum install zlib-devel libuuid-devel libmnl-devel gcc make git autoconf autogen automake pkgconfig
sudo yum install curl jq nodejs
Step 3: Install Netdata
Install Netdata with the official installation script:
cd ~
git clone https://github.com/firehol/netdata.git --depth=1
cd netdata
sudo ./netdata-installer.sh
During the installation process, Press
ENTER to start the installation.
If no errors occur during installation, the Netdata daemon will start.
Step 4: Modify firewall rules
Before you can access Netdata's web interface, you need to modify firewall rules to allow traffic on port 19999, the default communication port of Netdata:
sudo firewall-cmd --permanent --zone=public --add-port=19999/tcp
sudo firewall-cmd --reload
Step 5: View the monitoring interface
Confirm the installation by opening your web browser and visiting the monitoring interface of Netdata:
http://<your-Vultr-server-IP>:19999
[系統設定]
vim /etc/netdata/netdata.conf* global - 服務的全域設定
* plugins - 啟用或停用插件
* plugin:NAME - 各個插件的設定
* CHART_NAME - 各個圖表的設定
以預設值就已經可以正常的運作了，而這些參數可以視狀況修改：
* update every = 1，每一秒更新一次
* default port = 19999，預設通訊埠在 TCP 19999
* bind to = *，不綁定 IPv4、IPv6 位址
* disconnect idle web clients after seconds = 60，Web Client 閒置 60 秒後就踢掉
* enable web responses gzip compression = yes，啟用網頁 GZip 壓縮功能
