unbridled-41 opened a new issue, #4841:
URL: https://github.com/apache/rocketmq-dashboard/issues/4841
### Studio Version
Branch `rocketmq-studio` (development trunk), commit `4c697f07`.
### Runtime Environment
Front-end only: `web/src/pages/ops/alerts.tsx` +
`web/src/i18n/translations.ts`. Any browser.
### Describe the Bug
The alerts-page pagination footer renders the server total through the i18n
label:
```ts
showTotal={(total) => t('alerts.totalRules', { count: total })}
```
but the translation carries no placeholder:
```ts
'alerts.totalRules': { zh: '规则总数', en: 'Total Rules' },
```
`t()` performs a plain `String.replace('{count}', …)` loop, which is a no-op
when the template lacks the placeholder — the footer shows only "规则总数" / "Total
Rules" and **the total number is silently dropped**. Verified by simulating
`t('alerts.totalRules', { count: 21 })` → output is exactly `"规则总数"` (no `21`
anywhere in the footer text). The header stat block directly above *does* show
the number in a separate span, making the omission visible on every page load.
### Steps to Reproduce
1. Open the alerts page (either domain) with any page result.
2. Look at the pagination footer at the bottom-right of the table.
3. Observe the label "规则总数" / "Total Rules" with no number, while the header
stat shows the total.
### What Did You Expect to See?
The pagination footer renders the substituted label, e.g. "规则总数 21" / "Total
Rules 21", consistently with the header stat.
### What Did You See Instead?
Only the bare label; the count never appears in the footer.
### Additional Context
Proposed fix in PR #4832: add the `{count}` placeholder to
`alerts.totalRules` and render the header stat through the same substituted
label so the count appears wherever the label does. Note: the footer assertion
in the pre-existing test `loads a server-side page and filters by status and
search` (`expect(screen.getByText('21'))`) matched only the header stat's
separate span, which is why the missing footer number went unnoticed.
