[Question] <title>当告警信息解决之后，虽然做了分组收敛，但是消息仍然会持续发送
还是和告警消息发送相关
- 当我接入prometheus的告警规则，并且发送告警消息之后，程序中报错，以下为错误日志。
- 我的prometheus告警开始时间为:2025-11-03 15:13:47，但是消息发送是在2025-11-03 15:17:47才发送，延迟了4分钟之后消息才进行发送，prometheus的规则设置的for=2m

@qimy1314524
- This issue has been optimized and does not affect usage. #3772
- Could you elaborate on that? I assume you've integrated Prometheus? Can you post the relevant logs starting with
Receive prometheus server alert?
目前这个问题 我没有复现出来，初步怀疑当prometheus发送告警消息的时候，系统偶尔会出现宕机情况，刷新也无法正常显示，等之后再次遇到这个问题，我会截图提供给您。

@qimy1314524 Thanks again for your response
I believe the issue you're encountering is unrelated to hzb. I initially overlooked your screenshot information and mistakenly assumed you were integrating Prometheus monitoring via hzb. Later, I realized you were likely integrating Prometheus alert information through an integration interface.
Determining the status of integrated access is straightforward: if the endsAt in the Prometheus alert message is earlier than the alert_time (the time hzb received the alert), it is considered resolved; otherwise, it is considered firing.
You can focus on the log reception I mentioned above, or explore the lifecycle management of Prometheus alerts.
最近我又遇到了web页面错误问题,刷新的时候页面长时间无法显示,最终报错,再次刷新后,页面正常访问,这个时间段正是prometheus发送告警监控的时段.

Hi @qimy1314524 , thank you for following up. I've reviewed the content you provided. The second issue is identical to the one at #3772 . This exception is unrelated to the content displayed on your page. It does not affect normal usage and will be fixed in the next version.
Secondly, regarding your first question, I initially suspect this issue arises when navigating from the menu to a lazy-loaded route. If the dynamically imported frontend resources fail to load—for instance, due to outdated resources after a new version release, or network/proxy-related interruptions—it could trigger this problem.
The /api/alerts Unknown Error is the result of two independent connections failing simultaneously. This issue likely occurs when the browser cancels an ongoing HTTP request midway or a network layer failure occurs, causing the status to be set to 0, which in turn results in statusText='Unknown Error'.
I reproduced this issue by intercepting browser network requests. I recommend first clearing the cache and troubleshooting network-related issues.
Should you have any related questions, please feel free to continue the discussion.
