修改了模板没有生效 #37

修改了钉钉的模板，但是告警时还是发的老的模板内容，还有如果我想遍历所有label，怎么改模板哈

feiyu563 · 2020-06-28T08:22:36Z

你用的接口是模板接口：/prometheusalert吗，自定义模板必须对应自定义模板接口才能生效，并且模板的名称不能跟别的模板名称重复

哦哦，用的不是您说的这个接口，但是发现提示是多个告警，发出来的只显示了第一个告警，这个感觉还需要优化下

feiyu563 · 2020-06-29T01:43:15Z

老的接口尚未接入自定义模板，下一版本会接入

好的，我如果想把所有label都打印出来，模板该怎么设置呢，必须都写出来么

imlxh · 2020-06-29T01:54:01Z

类似于这种，每个JOB的内容可能都不一样，所以显示的时候也需要展示些关键信息

feiyu563 · 2020-06-29T01:54:35Z

参考#30

imlxh · 2020-06-29T01:56:31Z

这个我看了，是固定的，并没有展示所有内容，告警比较简练

xmx0632 · 2020-06-29T02:48:44Z

@feiyu563 你好，我在grafana里设置了发告警到 http://PrometheusAlert/grafana/dingding
从钉钉上可以接收到告警消息，如图

当是按照文档：https://github.com/feiyu563/PrometheusAlert/blob/master/doc/readme/tpltest.md 说的去日志中查看接收到的消息却没有如文档中说的关键字信息。

以下是我从日志中拿到的信息：

2020/06/29 02:37:15.400 [I] [value.go:460] [1593398235400197882] {"evalMatches":[],"message":"nacos db exception!!!","ruleId":27,"ruleName":"db exception alert","ruleUrl":"http://localhost:3000/d/Bz_QALEiz12/nacos-1?fullscreen\u0026edit\u0026tab=alert\u0026panelId=54\u0026orgId=1","state":"alerting","tags":{},"title":"[Alerting] db exception alert"}

请问这里需要如何定制模版呢？是不是文档与代码不同步？多谢

feiyu563 · 2020-06-29T02:54:49Z

这些就是grafana的json

{"evalMatches":[],"message":"nacos db exception!!!","ruleId":27,"ruleName":"db exception alert","ruleUrl":"http://localhost:3000/d/Bz_QALEiz12/nacos-1?fullscreen\u0026edit\u0026tab=alert\u0026panelId=54\u0026orgId=1","state":"alerting","tags":{},"title":"[Alerting] db exception alert"}

我在模版测试页面尝试发送消息会报错。可能是哪里的问题呢？多谢

遍历所有labels的模版试试这个

feiyu563 · 2020-06-29T03:05:41Z

你上面那个是grafana的告警消息，要用grafana的模版，而你用的prometheus的模版肯定会报错

debug后发现是grafana原来设置的模版中包含time方法调用导致的，删除包含time的调用之后就正常了。

Grafana告警信息

{{.ruleName}}

告警级别：严重

开始时间：{{ (time.Now).Format time.Kitchen }}{{ ((time.Now).Add (time.Hour 2)).Format time.Kitchen }}

{{.message}}

与传入的消息转换时没有time对象导致返回 nil 报错，在

PrometheusAlert/controllers/prometheusalert.go

Line 37 in 92ce2eb

tpl,_:=template.New("").Parse(tpltext.Tpl)

中打印转换异常可以看到报错信息

tpl,tplErr:=template.New("").Parse(tpltext.Tpl)
if tplErr != nil {
logs.Error("parse tpl error",tplErr)
}

Zhang21 · 2020-07-07T06:39:51Z

@feiyu563 @xmx0632 请问两位的alertmanger是怎么配置的？

我按照文档配置，那不是wxurl已经被写死了？那自己配置的其它机器人是否就不生效了？还有就是，app.conf里面配置是否也不生效了？时间转换这些都不生效。

找到需要使用的自定义消息模版，复制表格中路径一列的地址内容，并将地址中[xxxxx]中的地址或手机号替换成你实际的配置，将其粘贴到对应的WebHook地址配置中即可。

我只是像使用自定义的模板，但我还是需要继续使用app.conf里面的内容。关于多个机器人，关于时区等等。怎么解决？

Zhang21 · 2020-07-07T06:45:24Z

我能不能只填写模板地址，不填写其它配置，让它从app.conf里取读取？

Zhang21 · 2020-07-07T07:15:49Z

我使用sqlite3连数据库都改了，使用默认的接口还是不生效。

这个默认的告警模板是写死在代码里面的了吗？我连数据库都改了，哎！
