前言

在某些时候，由于网络方面的故障(例如：交换机调整或某机房网络波动),会导致成百上千服务器报警，由于报警邮件发送频繁导致邮箱被禁，zabbix仍尝试多次发送，最后导致zabbix堆积大量告警队列，然后产生延时。当网络恢复后，并且联系邮箱管理员解除限制后，仍能不断的收到延迟的报警和恢复邮件。
为了避免过时的报警，影响监控，我们需要把zabbix积压的消息处理掉，让它不再发送。

---

---

方法一

---

---

修改mysql的zabbix库alerts表,把状态改为已发送或发送失败

---

<1>为了避免误操作，alerts表备份

mysqldump -u账号 -p密码  zabbix alerts > alerts.sql

---

---

<2>查看待发送消息堆积的数量

use zabbix;
select count(*) from alerts;
select count(*) from alerts where status =0;

0待发送
1已发送
2发送失败

---

---

<3>修改未发送的为已发送

update zabbix.alerts set status = 1 where status = 0;

---

---

<4>重启zabbix-server

systemctl restart zabbix_server

---

---

<5>验证功能
关闭一个端口，是否有报警

---

---

---

方法二

---

---

直接清理alerts表，会导致action也被清理(不建议删库)

---

<1>为了避免误操作，alerts表备份

mysqldump -u账号 -p密码  zabbix alerts > alerts.sql

---

---

<2>获取创建表的语句

use zabbix;
show create table alerts；

---

---

<3>删除表

drop table alerts；

---

---

<4>使用获取的创建表语句创建

CREATE TABLE `alerts` (
  `alertid` bigint(20) unsigned NOT NULL,
  `actionid` bigint(20) unsigned NOT NULL,
  `eventid` bigint(20) unsigned NOT NULL,
  `userid` bigint(20) unsigned DEFAULT NULL,
  `clock` int(11) NOT NULL DEFAULT '0',
  `mediatypeid` bigint(20) unsigned DEFAULT NULL,
  `sendto` varchar(100) COLLATE utf8_bin NOT NULL DEFAULT '',
  `subject` varchar(255) COLLATE utf8_bin NOT NULL DEFAULT '',
  `message` text COLLATE utf8_bin NOT NULL,
  `status` int(11) NOT NULL DEFAULT '0',
  `retries` int(11) NOT NULL DEFAULT '0',
  `error` varchar(128) COLLATE utf8_bin NOT NULL DEFAULT '',
  `esc_step` int(11) NOT NULL DEFAULT '0',
  `alerttype` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`alertid`),
  KEY `alerts_1` (`actionid`),
  KEY `alerts_2` (`clock`),
  KEY `alerts_3` (`eventid`),
  KEY `alerts_4` (`status`,`retries`),
  KEY `alerts_5` (`mediatypeid`),
  KEY `alerts_6` (`userid`),
  CONSTRAINT `c_alerts_1` FOREIGN KEY (`actionid`) REFERENCES `actions` (`actionid`) ON DELETE CASCADE,
  CONSTRAINT `c_alerts_2` FOREIGN KEY (`eventid`) REFERENCES `events` (`eventid`) ON DELETE CASCADE,
  CONSTRAINT `c_alerts_3` FOREIGN KEY (`userid`) REFERENCES `users` (`userid`) ON DELETE CASCADE,
  CONSTRAINT `c_alerts_4` FOREIGN KEY (`mediatypeid`) REFERENCES `media_type` (`mediatypeid`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin

<5>重启zabbix-server
