Purpose

The coordinate pickers - cluster, namespace, pod, container - drew their options from the log lines already on screen. Those rows are the query's answer, so a picked namespace collapsed its own picker to that one value, and a pod that had not logged inside the window was never offered at all.

Opening a picker now asks the plane which values that filter can take across everything matching the current query (openchoreo/openchoreo#4719). Each value carries how many records use it, and typing narrows the list at the plane rather than in the browser.

One filter per request, and only for the picker being opened: each answer costs the plane an aggregation, so a page view that never opens the filters costs it nothing. The row owns which picker is open rather than each picker owning itself - that is what keeps a second from opening over the first, and makes "which one to ask about" something the row can act on.

A plane that cannot answer falls back to the values derived from the loaded rows, silently. Not a defensive extra: the endpoint is unmerged, so this is the path every deployment takes today and the page has to behave exactly as it did before. 404 and 501 are answered as null rather than thrown, so neither earns a retry nor an error banner for what is really "not here yet" - deliberately unlike the record query, where a 501 means there are no logs to show at all.

The pickers, the label selector and the level select are no longer disabled while logs load. That was already wrong, since the flag includes "load more" and paging therefore froze the filters; with per-picker values it would have blocked the very interaction that fetches them.

Summary by CodeRabbit

  • New Features

    • Platform log filter pickers now load values from the observability service when opened, including values from records not yet displayed.
    • Options show record counts and support server-side type-ahead searching.
    • Selected values remain visible even when absent from the latest results.
    • Filter, label, and log-level controls remain usable while logs load.
    • Older observability services fall back to the previous filter behavior.
  • Bug Fixes

    • Improved handling of unavailable, unsupported, or mismatched filter-value responses without disrupting log viewing.

The coordinate pickers - cluster, namespace, pod, container - drew their options
from the log lines already on screen. Those rows are the query's answer, so a
picked namespace collapsed its own picker to that one value, and a pod that had
not logged inside the window was never offered at all.

Opening a picker now asks the plane which values that filter can take across
everything matching the current query (openchoreo/openchoreo#4719). Each value
carries how many records use it, and typing narrows the list at the plane rather
than in the browser.

One filter per request, and only for the picker being opened: each answer costs
the plane an aggregation, so a page view that never opens the filters costs it
nothing. The row owns which picker is open rather than each picker owning
itself - that is what keeps a second from opening over the first, and makes
"which one to ask about" something the row can act on.

A plane that cannot answer falls back to the values derived from the loaded
rows, silently. Not a defensive extra: the endpoint is unmerged, so this is the
path every deployment takes today and the page has to behave exactly as it did
before. 404 and 501 are answered as null rather than thrown, so neither earns a
retry nor an error banner for what is really "not here yet" - deliberately
unlike the record query, where a 501 means there are no logs to show at all.

The pickers, the label selector and the level select are no longer disabled

paging therefore froze the filters; with per-picker values it would have blocked
the very interaction that fetches them.

📝 Walkthrough

Walkthrough

Platform log filter pickers request values from the observability plane when opened. Responses include record counts and support server-side search. The UI falls back to log-derived values when the plane cannot answer and remains enabled during log loading.

plugins/openchoreo-observability/src/api/ObservabilityApi.ts, plugins/openchoreo-observability/src/api/ObservabilityApi.platformLogs.test.ts, plugins/openchoreo-observability/src/components/PlatformLogs/types.ts
Adds filter-value request and response types, shared query-parameter handling, the observer API method, and API tests for requests and responses.

Makes picker state controlled, displays counts and loading state, forwards search text, preserves selected values, and uses log-derived fallback values.

Merge Risk: ⚪ Minimal · up to 1b3b3

The filter pickers retain their fallback behavior when the observer cannot answer, while successful empty searches remain empty. No actionable current-head risk remains.

In @.changeset/platform-logs-dashboard.md:
- Around line 21-24: Update .changeset/platform-logs-dashboard.md lines 21-24 to
describe filter values as coming from the full matching result set rather than
the loaded page, replacing the plane-wide wording. Update
.changeset/platform-logs-filter-values.md lines 8-13 to replace plane-wide and
“not logged recently” claims with an example of a pod absent from the loaded
page but present within the matching time window.

In `@plugins/openchoreo-observability/src/hooks/useDebouncedValue.ts`:
- Around line 20-24: Update useDebouncedValue so empty-string and nullish value
inputs are returned directly during render rather than synchronized via the
useEffect, ensuring cleared searches cannot expose the previous debounced value
after openFilter changes. Preserve the existing debounce behavior for non-empty
values and remove the effect-based cleared-value update.

In `@plugins/openchoreo-observability/src/hooks/usePlatformLogFilterValues.ts`:
- Line 75: Update the answered condition in usePlatformLogFilterValues to also
require !noLevels, preventing cached or keepPreviousData results from being
exposed when no log levels are selected. Preserve the existing data.filter
comparison for active log-level queries.
