Summary

Fixes #589.

The Hot Keys tab previously decided its mode (useHotSlots vs MONITOR) based on maxmemory-policy and cluster-slot-stats-enabled flags queried once at connect time and cached in the client connectionDetails. If either config changed at runtime (e.g. via CONFIG SET maxmemory-policy allkeys-lfu), the tab remained in the old mode until a reconnect.

Changes

1. Server (apps/server/src/actions/hotkeys.ts):

   • In hotKeysRequested, query live maxmemory_policy (via getKeyEvictionPolicy) and cluster-slot-stats-enabled (via getClusterSlotStatsEnabled) from the active connection client rather than relying exclusively on cached flags.
   • Dynamically compute useHotSlots for the metrics server request based on live configuration.
   • Return updated keyEvictionPolicy and clusterSlotStatsEnabled in the hotKeysFulfilled payload.

2. Frontend (apps/frontend/src/state/valkey-features/connection/connectionSlice.ts):

   • Added an extraReducer for VALKEY.HOTKEYS.hotKeysFulfilled to update connectionDetails.keyEvictionPolicy and connectionDetails.clusterSlotStatsEnabled across matching cluster/standalone connection entries.
   • This ensures the UI (ActivityView.tsx useHotSlots) immediately reacts to live configuration changes upon refresh without requiring a reconnect.

3. Tests:

   • Added test in hotkeys-commandlogs.test.ts verifying that hotKeysRequested re-reads live maxmemory_policy and cluster-slot-stats from the client and forwards useHotSlots=true to the metrics endpoint.
   • Added unit tests in connectionSlice.test.ts verifying connection details updates on hotKeysFulfilled for both cluster and standalone connections.

Walkthrough

Hot-keys requests now read live server configuration and use it to select hot-slot collection. Fulfilled responses include available settings, which the frontend applies to matching cluster or standalone connections.

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: Low · up to e6efe

Hot Keys now follows live server settings. If a settings query fails, the tab can wrongly fall back to a disabled mode and overwrite the stored settings with defaults. This is a narrow failure case and is easy to fix, so the change is mergeable with that follow-up.

Full details: Title check

Explanation

The title names the fix and its subject: hot keys mode updates dynamically when configuration changes. The changeset reads live maxmemory policy and cluster slot stats in hotKeysRequested, computes useHotSlots from them, and updates connection details on hotKeysFulfilled. The title is conventional and specific. It includes the issue reference (#589), which is acceptable but adds noise.

Full details: Linked Issues check

Explanation

[#589] The requirement is that Hot Keys mode follows the server's current maxmemory-policy and cluster-slot-stats-enabled values without a reconnect. At head, apps/server/src/actions/hotkeys.ts reads the live eviction policy through getKeyEvictionPolicy(client) on every hotKeysRequested call. For cluster clients it also reads getClusterSlotStatsEnabled(client). It then computes useHotSlots from these live values (slot stats enabled AND policy includes "lfu"), with request-payload flags used only as fallback when a read fails or no client is found. The fulfilled payload returns keyEvictionPolicy and clusterSlotStatsEnabled. In apps/frontend/src/state/valkey-features/connection/connectionSlice.ts, an extraReducer for VALKEY.HOTKEYS.hotKeysFulfilled writes those values into connectionDetails for matching cluster (clusterId) or standalone (toNodeId(connId) === nodeId) entries. The UI therefore receives the updated mode on refresh without reconnecting. The issue has no non-coding requirements. Limits of this check: the metrics server handling of useHotSlots and the ActivityView rendering were not inspected. The test files were described in the PR summary but their contents were not read.

Full details: Out of Scope Changes check

Explanation

All changed areas map to #589: the server hot-keys action (live config reads, useHotSlots computation, configUpdates in the payload), the connection slice reducer that stores those values, and tests for both. The server change adds a clients dependency to hotKeysRequested, which is needed for the live reads. No unrelated feature or refactor was identified. One minor discrepancy: the PR summary says each setting falls back independently. The code at head wraps Promise.all(getKeyEvictionPolicy, getClusterSlotStatsEnabled) in a single try/catch, so a failure of one read leaves both live values undefined and both fall back to request flags. This is a behavior detail, not an out-of-scope change.

Full details: Description check

Explanation

The description states the problem, lists the server and frontend changes, and describes the tests. It links the issue with 'Fixes #589.' It does not follow the repository template exactly: it has no '## Description' heading and no 'Change Visualization' section with a before/after screenshot or video. The template asks for that section, and the author did not fill it in or mark it not applicable.

Resolution

Add the '## Description' heading to match the template. Add the '### Change Visualization' section. Include a before and after screenshot or video of the Hot Keys tab, or state why a visual is not applicable (for example, a backend-only check).

Minor · Functional Correctness · Quick win

Preserve the request flags when live configuration queries fail.

If either query fails, its helper catches the error and returns a defined default: NO_EVICTION or false. These defaults bypass the undefined-based fallback at Lines 101–107. A request with both cached flags enabled then omits useHotSlots, and the fulfilled response overwrites the connection settings with values that were not read successfully.

Make these calls distinguish an unavailable value from a confirmed disabled setting. Use the request flag for each unavailable value, and omit that configuration update from the response.
