本文将主要说明QuickAlarm该如何使用,以及使用时需要注意事项

1. 基本使用姿势

首先我们不做任何的自定义操作,全部依靠系统默认的实现,我们的使用步骤如下

1. 添加注册文件

首先在项目的资源目录下,添加注册文件 alarm.properties,文件内容如下

1
2
3
4
5
6
7
8
9
10
11
12
13
## 应用名,必填
appName=test

## 报警规则文件所在的路径,如果采用系统默认加载方式,必填
## / 开头,表示存的是绝对路径
## 非/开头,表示存的是系统相对路径,一般是放在资源目录下
alarmConfPath=/tmp/alarmConfig

## 最大的报警类型,非必填
maxAlarmType=1000

## 默认报警用户,必填
defaultAlarmUsers=yihui

具体存放的位置,可以参考下图,放在resources目录下(源码中,是放在测试资源目录下的)

IMAGE

2. 添加报警规则

根据注册文件中指定的路径,设置报警规则文件,如我们的报警规则文件

内容为json串格式,支持格式化的json串解析,为了节省篇幅,下面压缩成一行,点击获取json格式化小工具

/tmp/alarmConig:

1
{"default":{"level":"LOG","autoIncEmergency":true,"max":30,"min":3,"threshold":[{"level":"SMS","threshold":20,"users":["345345345345","123123123123"]},{"level":"WEIXIN","threshold":10,"users":["yihui","erhui"]},{"level":"LOG","threshold":5,"users":["yihui","erhui"]}],"users":["yihui"]},"NPE":{"level":"WEIXIN","autoIncEmergency":false,"max":30,"min":0,"threshold":[{"level":"SMS","threshold":20,"users":["345345345345","123123123123"]},{"level":"WEIXIN","threshold":10,"users":["3h    ui","4hui"]}],"users":["yihui"]},"XXX,YYY":{"level":"EMAIL","autoIncEmergency":true,"max":30,"min":3,"threshold":[{"level":"SMS","threshold":20,"users":["345345345345","123123123123"]},{"level":"WEIXIN","threshold":10,"users":["yihui","erhui"]},{"level":"EMAIL","threshold":5,"users":["yihui@xxx.com","erhui@xxx.com"]}],"users":["yihui@xxx.com"]}}

3. 测试类

一个简单的使用测试

@Test
public void sendMsg() throws InterruptedException {
String key = "NPE";
String title = "NPE异常";
String msg = "出现NPE异常了!!!";
AlarmWrapper.getInstance().sendMsg(key, title, msg); // 微信报警

// 不存在异常配置类型, 采用默认报警, 次数较小, 则直接部署出
AlarmWrapper.getInstance().sendMsg("zzz", "不存在xxx异常配置", "报警嗒嗒嗒嗒");

Thread.sleep(1000);
}

II. 报警执行机器扩展

前面的报警规则配置中,有WEIXIN, SMS, EMAIL的报警,但是系统只提供了两个NONE和LOG,所以我们可以看下如何自定义实现上面的三个

1. 实现IExecute接口

邮件报警

1
2
3
4
5
6
public class EmailExecute extends LogExecute {
@Override
public void sendMsg(List<String> users, String title, String msg) {
super.sendMsg(users, title, msg);
}
}

短信报警

3
4
5
6
7
8
9
10
/**
* Created by yihui on 2018/2/7.
*/
public class SmsExecute extends LogExecute {

@Override
public void sendMsg(List<String> users, String title, String msg) {
super.sendMsg(users, title, msg);
}
}

微信报警

1
2
3
4
5
6
7
8
9
/**
* Created by yihui on 2018/2/7.
*/
public class WeiXinExecute extends LogExecute {
@Override
public void sendMsg(List<String> users, String title, String msg) {
super.sendMsg(users, title, msg);
}
}

说明,因为没有具体的实现,所以我们直接用日志输出来模拟,所以就都继承了LogExecute, 实际使用中,可以在上面补上相应的实现代码

2. 添加SPI定义

在 resources 目录下,新增

  • 目录:META-INF/services/
  • 文件:com.hust.hui.alarm.core.execut.api.IExecute

文件内容为上面几个实现类的全路径

1
2
3
com.hust.hui.alarm.core.test.execute.EmailExecute
com.hust.hui.alarm.core.test.execute.SmsExecute
com.hust.hui.alarm.core.test.execute.WeiXinExecute

目录结构如:

public static void main(String[] args) throws InterruptedException {
// 测试异常升级的case
// 计数 [1 - 2] 默认报警(即无日志) (其中 < 3 的是因为未达到下限, 采用的默认报警)
// 计数 [3 - 4] 默认邮件报警(其中 < 5 采用的默认报警, 与下面的区别是报警用户)
// 计数 [5 - 9] 邮件报警 (大于5小于10根据上升规则,还是选择邮件报警)
// 计数 [10 - 19] 微信报警
// 计数 [20 - 30] 短信报警
// 计数 [31 -] 默认报警 (超过上限, 不报警)
for (int i = 0; i < 40; i++) {
new Thread(new Runnable() {
@Override
public void run() {
AlarmWrapper.getInstance().sendMsg("YYY", "异常报警升级测试");
}
}).start();
}


Thread.sleep(1000 * 600);
}

实测输出结果如下:

III. 报警规则加载自定义

1. 实现IConfLoader接口

自定义加载器,给了一个最基本的

public class SelfAlarmConfLoader implements IConfLoader {
@Override
public RegisterInfo getRegisterInfo() {
RegisterInfo registerInfo = new RegisterInfo();
registerInfo.setMaxAlarmType(100);
registerInfo.setDefaultAlarmUsers("yihui");
registerInfo.setAppName("test");
return registerInfo;
}

@Override
public boolean alarmEnable() {
return true;
}

@Override
public int order() {
return 0;
}

@Override
public AlarmConfig getAlarmConfig(String alarmKey) {
//db 查询,获取对应的配置信息
// 下面是模拟,返回一个固定的配置
AlarmConfig alarmConfig = new AlarmConfig();
alarmConfig.setAlarmLevel("WEIXIN");
alarmConfig.setAutoIncEmergency(false);
alarmConfig.setMinLimit(10);
alarmConfig.setMaxLimit(14);
alarmConfig.setUsers(Arrays.asList("yihui"));
alarmConfig.setAlarmThreshold(Collections.emptyList());
return alarmConfig;
}
}

2. 添加SPI配置

在resources目录下新增

  • 目录: META-INF/services
  • 文件: com.hust.hui.alarm.core.loader.api.IConfLoader

文件内容

1
com.hust.hui.alarm.core.test.loader.SelfAlarmConfLoader

3. 测试

同样是上面的代码,输出结果

18:43:04.275 [sms-sender1-thread-2] INFO  alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg:  ip:172.17.13.18 >>> key:YYY >>> 异常数: 10 >>> 异常报警升级测试
18:43:04.275 [sms-sender1-thread-4] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 12 >>> 异常报警升级测试
18:43:04.276 [sms-sender1-thread-1] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 11 >>> 异常报警升级测试
18:43:04.275 [sms-sender1-thread-5] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 14 >>> 异常报警升级测试
18:43:04.275 [sms-sender1-thread-3] INFO alarm - Do send msg by WEIXIN to user:[yihui], title: [test], msg: ip:172.17.13.18 >>> key:YYY >>> 异常数: 13 >>> 异常报警升级测试

4. 说明

系统默认的order是10,所以如果在测试上面的第二步时,不妨把com.hust.hui.alarm.core.test.loader.SelfAlarmConfLoader#order返回值,改成大于10,这样就会走到默认的配置加载类

采用 SelfAlarmConfLoader 时,前面说的两个基础配置文件,是可以没有的,完全不会有任何影响,因为对应的注册类和报警规则,都是右这个类内部提供了
