[I] [Bug] A failed alert read leaves the System Alerts page claiming "0 unacknowledged" with no retry [rocketmq-dashboard]
iloveeyjafjalla opened a new issue, #6491:
URL: https://github.com/apache/rocketmq-dashboard/issues/6491
### Before Creating the Bug Report
- [x] I have searched the [open issues](https://github.com/apache/rocketmq-dashboard/issues) of this repository and believe that this is not a duplicate.
- [x] This is a defect in RocketMQ Studio, not a usage question and not a defect in another Apache RocketMQ repository.
- [x] I can reproduce this on the current `master` branch, or I have stated the exact version I am running below.
### Studio Version
branch: rocketmq-studio (target branch)
git commit id: 779b8c0e
### Runtime Environment
OS: Windows 11 (10.0.26200) · Chrome, frontend dev server + Spring Boot backend on the local stack
### Connected RocketMQ Cluster
RocketMQ version: 5.3.2 (apache/rocketmq nameserver + broker); not required to reproduce — the defect is client-side
### Build Toolchain
JDK: 21.0.12.1+1 · Maven: 3.9.9 · Node: 20.19.5
### Describe the Bug
When the alert query fails (backend down, gateway error, request aborted), the System Alerts page (`ops/system-alerts`) keeps presenting the feed as if it had been read successfully and were empty:
- the header subtitle still claims `本页 0 条未确认` / `0 unacknowledged on this page`, because `unackCount` is computed from the empty `alerts` array (`web/src/pages/ops/systemAlerts.tsx:243`, subtitle at `:481`);
- the per-level chips render counts derived from that same empty array (`:526`);
- the only signal is a transient toast (`message.error(t('sysAlerts.loadFailed'))` at `:216`), which disappears and leaves nothing on the page.
An operator who misses the toast reads the page as "no unacknowledged alerts" — the opposite of a failed read — and the page offers no way to retry except changing a filter.
### Steps to Reproduce
1. Start RocketMQ Studio and open the System Alerts page (`ops/system-alerts`).
2. Make the alert query fail — for example stop the backend (or let the gateway refuse the request) and then reload, or change a filter/page so the list effect refetches.
3. The page keeps claiming "本页 0 条未确认" / "0 unacknowledged on this page" and shows the empty feed state, while the failure only appears as a toast. No retry control appears.
Deterministic check used for the fix: `web/src/pages/ops/__tests__/SystemAlertsPage.test.tsx` with `listSystemAlertsPage` rejecting the first call. On the current target branch the new case fails with `Unable to find an element with the text: 获取数据失败`; with the fix it passes and the retry recovers the feed.
### What Did You Expect to See?
A failed read should stay visible on the page and must not be rendered as a measured result:
- the header must not assert a count it never read;
- the page should surface the failure and offer a retry that re-runs the query in place.
### What Did You See Instead?
Found while reviewing the failure states of the ops pages. Sibling fixes already landed or are in review for the same class: the instance-list failure state (#6348), the audit page (#6485), and `fix(alerts): stop reporting a failed silence read as no maintenance windows` (#6127) for the maintenance-windows dialog of this same page — that one covers the dialog, not this feed.
Failure path on 779b8c0e: list effect at `web/src/pages/ops/systemAlerts.tsx:204-216`; `getCollectorStatus` tolerates its own failure separately.
I plan to submit a fix with a regression test. Drafted with AI assistance; the analysis and this text were reviewed before posting.

Resolved by #6492 (merged into `rocketmq-studio` as [`77dcf962e`](https://github.com/apache/rocketmq-dashboard/commit/77dcf962e)). The merge target is not the default branch, so this issue does not auto-close.
