Nightingale简介与搭建

一、Nightingale简介

夜莺（ Nightingale ）是一款国产开源、云原生监控系统，Nightingale 在 2020.3.20 发布 v1 版本，目前是 v5 版本，从这个版本开始，与 Prometheus、VictoriaMetrics、Grafana、Telegraf、Datadog 等生态做了协同集成，力争打造国内最好用的开源运维监控系统。出自 Open-Falcon 研发团队。夜莺监控项目，于 2022 年 5 月 11 日，捐赠予中国计算机学会开源发展委员会(CCF ODC)，为 CCF ODC 成立后接受捐赠的首个开源项目。

Nightingale 可以接收各种采集器上报的监控数据，转存到时序库（可以支持Prometheus、M3DB、VictoriaMetrics、Thanos等），并提供告警规则、屏蔽规则、订阅规则的配置能力，提供监控数据的查看能力，提供告警自愈机制（告警触发之后自动回调某个webhook地址或者执行某个脚本），提供历史告警事件的存储管理、分组查看的能力。

EOF

systemctl daemon-reload
systemctl enable prometheus
systemctl restart prometheus
systemctl status prometheus

2.n9e安装

2.1 安装

mkdir -p /opt/n9e && cd /opt/n9e

# 去 https://github.com/didi/nightingale/releases 找最新版本的包，文档里的包地址可能已经不是最新的了
tarball=n9e-5.8.0.tar.gz
urlpath=https://github.com/didi/nightingale/releases/download/v5.8.0/${tarball}
wget $urlpath || exit 1

tar zxvf ${tarball}

mysql -uroot -p1234 < docker/initsql/a-n9e.sql
# check logs
# check port

2.2 系统服务配置

2.2.1 n9eserver

cat <<EOF >/etc/systemd/system/n9e-server.service

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable n9e-server
systemctl restart n9e-server
systemctl status n9e-server

2.2.2 n9e-webapi

cat <<EOF >/etc/systemd/system/n9e-webapi.service
[Unit]
Description="n9e-webapi"

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable n9e-webapi
systemctl restart n9e-webapi
systemctl status n9e-webapi

3.采集器-telegraf安装

3.1 linux系统安装

1.1 安装

cd /usr/local/src;
wget -S https://dl.influxdata.com/telegraf/releases/telegraf-1.22.4_linux_amd64.tar.gz
tar -zxvf telegraf-1.22.4_linux_amd64.tar.gz
cp telegraf /opt/

1.2 使用脚本启动

cat <<EOF > /opt/telegraf/start.sh
#!/bin/bash


case "$1" in
   "start") 
     cd /opt/telegraf;
     nohup /opt/telegraf/telegraf --config telegraf.conf &
   ;;
   "shutdown") 
     pid=$(ps aux|grep telegraf|grep -v 'grep'|awk '{print $2}')
     kill $pid
     kill $pid
     kill $pid
   ;;
   "restart") 
     pid=$(ps aux|grep telegraf|grep -v 'grep'|awk '{print $2}')
     kill $pid
     kill $pid
     kill $pid

     sleep 2s

     cd /opt/telegraf;
     nohup /opt/telegraf/telegraf --config telegraf.conf &
 
   ;;
   *) 
      echo "telegraf error"
      echo "$0 (start|shutdown|restart)"
   ;;
esac
EOF

sh start.sh restart

1.3 配置为系统服务
