HertzBeat是一款免Agent的监控平台，拥有强大自定义监控能力，可以对应用服务、数据库、中间件、操作系统、云原生等进行监控，配置告警阈值，以及告警通知(邮件微信钉钉飞书)。关于这个软件的介绍，我这里就不做过多的介绍了，感兴趣的可以去官网（https://hertzbeat.com/docs）去详细了解下。
今天我主要和大家分享下，如何使用docker来配置和运行HertzBeat。
HertzBeat将监控历史数据存储在时序数据库里面，官方文档给出了两款兼容的时序数据库软件，分别是IoTDB和TDengine，这里我使用的是TDengine。
首先，我们将所需的docker镜像下载到虚拟机（Docker已经提前安装，版本为20.10.21）。

Status: Downloaded newer image for tdengine/tdengine:2.4.0.12
docker.io/tdengine/tdengine:2.4.0.12然后，我们通过下面的命令来运行TDengine数据库
docker run -dti -p 6030-6049:6030-6049 -p 6030-6049:6030-6049/udp \
-v /data/taosdata:/var/lib/taos \
-e TZ=Asia/Shanghai \
--name tdengine tdengine/tdengine:2.4.0.12数据库root用户的默认密码是taosdata，这里我将其修改为其他密码，通过docker exec进入容器内部执行下面的命令。
# docker exec -it tdengine /bin/bash
root@77a11dd2b845:~/TDengine-server-2.4.0.12# taos
taos> show databases;
taos> CREATE DATABASE hertzbeat KEEP 90 DAYS 10 BLOCKS 6 UPDATE 1;
Query OK, 0 of 0 row(s) in database (0.001995s)
taos> alter user root pass 'YourPassword';
Query OK, 0 of 0 row(s) in database (0.002024s)
taos> quit
root@77a11dd2b845:~/TDengine-server-2.4.0.12# exit
exit备注：
CREATE DATABASE hertzbeat KEEP 90 DAYS 10 BLOCKS 6 UPDATE 1
创建一个名为 hertzbeat 的库，这个库的数据将保留90天（超过90天将被自动删除），每 10 天一个数据文件，内存块数为 6，允许更新数据
下面，我们修改HertzBeat的两个关键的配置文件，分别是application.yml和sureness.yml

在/data目录下创建上面两个文件，然后运行HertzBeat即可
docker run -dti -p 1157:1157 \

--name hertzbeat tancloud/hertzbeat:latest运行成功后，我们可以使用docker ps查看tdengine数据库实例和HertzBeat实例的进程。

在仪表盘，我们可以看见配置的监控的总览
下面分享下相关监控的趋势图：
1）服务器可用性监控
2）网页可用性监控
3）端口可用性监控
4）系统资源使用监控
5）中间件监控
备注：Tomcat中间件监控，跨服务器监控，要在catalina.sh里面配置开启JMX，还需要在tomcat-user.xml里面配置监控用户。

监控告警测试：
模拟停掉Tomcat服务，然后再启动，就会出现下面的告警列表，看起来还是很清晰的。
在告警中心可以看见更加详细的告警信息记录：
总结，这款软件监控的对象还是很广的，监控配置也很简单。但是，监控数据的GUI展示和目前流行的Grafana相比，还是界面还是很简陋的，期待后期可以完善和提升。另外，软件的安全性也有待提升，因为明文密码配置在文件中，在生产环境中（尤其是大厂）肯定是不被安全所允许的。
