WalkthroughIntroduces a statusPage prop to control conditional rendering of StatusPageBarChart, wires it through the Status page, and augments the server aggregation to include monitors’ uptimePercentage. Refactors the Bar component in StatusPageBarChart to use forwardRef without changing its behavior or public API. Changes

- return monitor?.status == true ? "up" : "down"; + return monitor?.status === true ? "up" : "down";

150-164: Confirm intent: uptimePercentage is computed over only the last 25 checks.This yields a “recent uptime” metric, not all-time or time-windowed uptime. If that’s desired—great. If not, adjust the $limit or compute over a defined window.

🛠️ Refactor suggestion
Default to showing uptime unless explicitly disabled (align with showCharts semantics).
Currently uptime hides when showUptimePercentage is undefined. Mirror the “!== false” pattern.

In client/src/Pages/StatusPage/Status/Components/MonitorsList/index.jsx around
lines 39 to 43, the uptime props currently only show when
statusPage.showUptimePercentage is truthy, causing uptime to hide when the flag
is undefined; change the checks to use "!== false" so uptime is shown by default
(i.e., pass monitor.percentageColor and monitor.percentage when
statusPage.showUptimePercentage !== false, otherwise null) and leave showURL
as-is.

Auto Pull Request Review from LlamaPReview
🎯 TL;DR & Recommendation
Recommendation: Request Changes
This PR enhances the status page with new toggles and fixes warnings but introduces a critical data inconsistency in uptime calculations that could mislead users.
🌟 Strengths
- Successfully resolves React prop-type and ref warnings, improving code quality.
- Adds configurable visibility for uptime percentages and charts, enhancing user control.
🚨 Critical Issues (P1)
- server/src/db/mongo/modules/statusPageModule.js: Introduces a data inconsistency that could confuse users with divergent uptime values between different pages.
💡 Suggestions (P2)
- client/src/Hooks/useMonitorUtils.js: Changes return type to string, risking breakage in other components expecting numeric percentages.
- client/src/Pages/StatusPage/Status/Components/MonitorsList/index.jsx: Uses hardcoded flex values, potentially causing layout overflow or misalignment on different screens.
- client/src/Components/Charts/StatusPageBarChart/index.jsx: Enforces minimum bar height, which distorts proportional accuracy of response times.
- server/src/db/mongo/modules/statusPageModule.js: CORS changes not visible; if implemented, incomplete headers could break client requests.
⚠️ **Unanchored Suggestions (Manual Review Recommended)**
The following suggestions could not be precisely anchored to a specific line in the diff. This can happen if the code is outside the changed lines, has been significantly refactored, or if the suggestion is a general observation. Please review them carefully in the context of the full file.
📁 File: server/src/db/mongo/modules/statusPageModule.js
Speculative: The PR description claims CORS wildcard headers were replaced with an explicit list, but the provided diff does not show this change. If implemented, explicit headers reduce attack surface but risk breaking clients if the list is incomplete. Without code visibility, we cannot assess the completeness of the allowed headers.
Suggestion:
Ensure allowed headers include all required headers (e.g., `Content-Type`, `Authorization`, custom headers). Validate against frontend requests.Related Code:

P1 | Confidence: High
The PR introduces a new server-side computation for monitors.uptimePercentage in the status page aggregation pipeline. However, the existing architecture already maintains an uptimePercentage field in the MonitorStats model (evidenced by related_context), which is updated by statusService.js using the formula stats.totalUpChecks / stats.totalChecks. This creates two independent calculations for the same metric. The aggregation uses the current monitor's checks array, which may be limited to recent checks (e.g., last 24 hours), while MonitorStats aggregates all historical checks. This inconsistency could cause divergent uptime values between the status page and other system components (e.g., monitor details views), confusing users and undermining data reliability.
Code Suggestion:
Consider using the precomputed `MonitorStats.uptimePercentage` instead of recalculating it in the aggregation. Alternatively, ensure the aggregation uses the same data scope as `MonitorStats` (all checks, not a subset).| <StatusPageBarChart checks={monitor?.checks?.slice().reverse()} /> | ||

P2 | Confidence: High
The conditional flex values (1 vs 10) introduce layout fragility. The hardcoded values assume a specific ratio between chart and label space, which may not hold across different screen sizes or content lengths. This could cause overflow or alignment issues when charts are hidden, especially if status labels vary in length. The related_context does not show similar layout patterns elsewhere, increasing maintenance overhead.
Code Suggestion:
Use responsive flex values (e.g., `{ xs: 1, md: 10 }`) or CSS Grid for more robust layout control.

P2 | Confidence: Medium
The fallback for missing uptimePercentage changes the return type of getMonitorWithPercentage() from a number to a string ("--") in some cases. The related_context shows this hook is widely used (e.g., monitorHooks.js, useStatusPageFetch.jsx), and consumers may expect a numeric percentage for formatting or calculations. While the immediate usage in MonitorsList (updated in this PR) handles strings, other consumers might break if they assume numeric input. This type inconsistency introduces subtle technical debt.
Code Suggestion:
Consider maintaining numeric types consistently (e.g., return `0` or `null` for missing data) and let UI components handle presentation fallbacks.

Hi @antonstrover, Can you please separate this pull request into individual features/fixes so we can address them one at a time? I realize the changes aren't huge, but it is far easier for us to review and approve code if each PR is focused on one feature or fix. Thank you! |

Imports
Added forwardRef from react.
Kept useTheme, MUI imports, and utilities.
Component: Bar
Before:
const Bar = ({ width, height, backgroundColor, borderRadius, children, ...otherProps }) => { … }
After is wrapped with forwardRef:
const Bar = forwardRef((props, ref) => …) so MUI Tooltip can attach a ref to the rendered element.
Forwarded ref to <Box ref={ref} … />
Continued to compute sx={{ borderRadius: borderRadius || theme.spacing(1.5) }} using theme.spacing(1.5) gives you a consistent fallback radius.

Signature & props
Before: const MonitorsList = ({ isLoading = false, shouldRender = true, monitors = [] }) => { … }
After: const MonitorsList = ({ isLoading = false, shouldRender = true, monitors = [], statusPage = {} }) => { … }
Added statusPage input so the list can respect page-level toggles.
Rendering changes
Previously always rendered the chart area; you had:
<Box flex={9}>
<StatusPageBarChart checks={(monitor?.checks).slice().reverse()} />
</Box>
Now guard it:
{statusPage.showCharts !== false && (
<Box flex={9}>
<StatusPageBarChart checks={monitor?.checks?.slice()?.reverse()} />
</Box>
)}
Meaning: charts render by default, but a showCharts: false flag on the status page hides them.
PropTypes
Added statusPage: PropTypes.object alongside the existing monitors: PropTypes.array.isRequired.

Added a $lookup to join monitorstats:
