Description

Adds time-based filtering to ClusterLogForwarder drop filters through a new olderThan condition. Values may be specified as YYYY-MM-DD dates or RFC3339 timestamps with explicit offsets; date-only values are interpreted as midnight UTC.

The change updates the API types, CRD schemas, CSV metadata, Vector filter/input configuration, and operator documentation. It also tightens CEL drop-condition validation so each condition must define either olderThan or a field-based match, while preventing invalid combinations such as missing match expressions or simultaneous matches and notMatches.

Testing

Adds coverage for:

  • Valid and invalid olderThan formats and timestamps
  • Conflicting or incomplete drop conditions
  • Application, infrastructure, and audit log filtering
  • Boundary behavior around the cutoff timestamp
  • Ensuring dropped records remain absent after subsequent log writes

High-Level Assessment

The following are alternative approaches to this PR:

1. Filter at individual sources
  • ➕ Could avoid processing historical records downstream
  • ➕ May reuse source-specific age controls where available
  • ➖ Not consistently supported across application, infrastructure, and audit sources
  • ➖ Cannot compose the cutoff with field match conditions
  • ➖ Would duplicate behavior across source implementations
2. Use a relative age duration
  • ➕ Convenient for continuously moving retention windows
  • ➕ Avoids periodically updating an absolute cutoff
  • ➖ Evaluation time introduces changing behavior and replay ambiguity
  • ➖ Requires additional duration syntax and validation
  • ➖ Does not match the requested deterministic historical boundary

Recommendation: Keep the absolute olderThan condition in the shared drop-filter layer. It provides deterministic, source-independent semantics and composes with existing field conditions; normalizing source event timestamps is the appropriate supporting change for accurate comparisons.

Action required

1. HTTP audit records ignore time filters ✓ Resolved 🐞 Bug ≡ Correctness
Description
buildOlderThanCondition evaluates root .timestamp, but the HTTP receiver calls
NewAuditInternalNormalization with parseIntoStructured=false, so its stageTimestamp and
requestReceivedTimestamp are never copied into ._internal.timestamp. ViaQ consequently assigns a
missing timestamp to the root record and the predicate coalesces the parse failure to false,
affecting audit events delivered through the supported HTTP receiver.
Code

internal/generator/vector/filter/drop/filter.go[R56-61]

+func buildOlderThanCondition(olderThan string) (string, error) {
+	cutoff, err := normalizeOlderThan(olderThan)
+	if err != nil {
+		return "", err
+	}
+	return fmt.Sprintf(`((parse_timestamp(to_string(.timestamp) ?? "", "%%+") < t'%s') ?? false)`, cutoff), nil
Relevance

●●● Strong

HTTP audit normalization skips timestamp extraction, so olderThan silently evaluates false for
supported audit records.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The new predicate reads root .timestamp; the HTTP receiver explicitly disables structured audit
parsing, while the shared normalizer only extracts audit timestamps when that flag is enabled. ViaQ
copies only ._internal.timestamp to the root, and the existing HTTP fixture demonstrates that
received audit events provide stageTimestamp and requestReceivedTimestamp rather than a root
timestamp.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

Issue description
`olderThan` evaluates `.timestamp`, but HTTP receiver audit events retain their timestamps under `._internal.structured` and never populate `._internal.timestamp`. The filter therefore treats valid HTTP-delivered audit events as having no parseable timestamp and keeps them.

Fix Focus Areas
- internal/generator/vector/input/receiver.go[35-42]
- internal/generator/vector/input/internal.go[61-72]
- internal/generator/vector/filter/drop/filter.go[56-61]

Recommended Fix
Add receiver-specific audit timestamp normalization that parses `._internal.structured.stageTimestamp`, falling back to `._internal.structured.requestReceivedTimestamp`, and assigns the parsed result to `._internal.timestamp` before ViaQ normalization. Add functional coverage for an HTTP kube-audit receiver with an `olderThan` drop condition.

2. Old invalid filters begin dropping logs ✓ Resolved 🐞 Bug ≡ Correctness
Description
validateDropCondition no longer rejects conditions containing both matches and notMatches,
while generation selects matches and silently ignores notMatches. A resource persisted under the
previous CRD can therefore become operator-valid after upgrade and activate an ambiguous drop rule
because CEL validation is not rerun when controllers read existing objects.
Code

internal/validations/observability/filters/validate_filters.go[L54-56]

-			// Validate only one of matches/notMatches is defined
-			if testCondition.Matches != "" && testCondition.NotMatches != "" {
-				testErrors = append(testErrors, "only one of matches or notMatches can be defined at once")
Relevance

●●● Strong

Removing internal conflict validation lets legacy invalid objects reach generation with matches
silently taking precedence.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The current validator chooses notMatches for regex compilation but never reports that both
expressions are present, whereas the generator chooses matches first. Existing objects are fetched
and validated internally during reconciliation, so the new API-server CEL rule does not protect
already persisted resources.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The internal validator no longer rejects a drop condition containing both match expressions, so an existing resource that was previously operator-invalid can become active after upgrade and silently use only `matches`.

## Fix Focus Areas
- internal/validations/observability/filters/validate_filters.go[66-92]
- internal/validations/observability/filters/validate_filters_test.go[48-120]

## Recommended Fix
Make `validateDropCondition` enforce the same structure as the CRD CEL rules: require exactly one of `olderThan` or `field`, require exactly one match expression for a field, and reject match expressions without a field. Restore unit coverage for simultaneous `matches` and `notMatches`.

Remediation recommended

3. Invalid cutoffs pass API validation ✗ Dismissed 🐞 Bug ≡ Correctness
Description
The olderThan schema pattern uses [0-2]\d for both clock and offset hours, admitting values from
24 through 29. Values such as 2026-09-16T24:00:00Z and 2026-09-16T00:00:00+24:00 pass API
schema validation but are rejected later by validateOlderThan and Go time parsing during transform
generation, leaving an admitted resource unable to generate collector configuration.

Relevance

●●● Strong

Schema admits hours 24–29 that internal validation rejects, directly undermining the new API
contract.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The API marker and generated CRD manifests share the permissive hour pattern, while the
controller-side regex restricts offset hours to 00–23 and semantic validation delegates to Go
timestamp parsing. Existing tests explicitly expect offset hour 24 to be rejected internally,
demonstrating that the API schema admits inputs that reconciliation and filter generation cannot
use.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The API pattern for `olderThan` permits impossible timestamp and timezone-offset hours from 24 through 29. This disagrees with later validation and transform generation, which reject those values after the API server has admitted the resource.

## Fix Focus Areas

- internal/validations/observability/filters/validate_filters.go[19-21]

## Recommended Fix
Replace the clock-hour and offset-hour `[0-2]\d` expressions with `(?:[01]\d|2[0-3])`, regenerate the CRD and bundle manifests, and add API-validation cases proving that a `24` timestamp hour and a `+24:00` offset are rejected.

- Around line 68-98: Update validateDropCondition to enforce mutually exclusive
condition shapes: allow OlderThan only when Field, Matches, and NotMatches are
empty, and report that combination while still validating OlderThan. For
non-OlderThan conditions, require exactly one non-empty match expression
alongside Field, returning before regex compilation when neither is provided;
use hasMatch and hasNotMatch consistently for the exclusivity check.

I see we are testing these to confirm both orders but I wonder if we should be normalizing the sort order of conditions. I wonder if we potentially have cases where we bounce the collector because the order came back differently between reconciliations

Verification Complete — olderThan drop filter (PR #3467)

Setup performed

1. Removed vector checkpoints on both nodes (rm -rf /var/lib/vector/openshift-logging) so the fresh collector re-reads the full journal/container history — guaranteeing there are logs older than the cutoff to exercise the drop.
2. Deployed the HTTP receiver from hack/manifests/receivers/http (oc apply -k) — vector http_server on :8090 writing received records to files by type.
3. Created a ClusterLogForwarder (collector) collecting infrastructure logs → drop filter → http receiver. Cutoff computed as now − 5 min = 2026-09-22T18:51:22Z.

The operator generated the expected vector filter transform:
[transforms.pipeline_infra_drop_older_than_5m_1]   # type = filter
condition = !(((parse_timestamp(to_string(.timestamp) ?? "", "%+") < t'2026-09-22T18:51:22Z') ?? false))
→ keeps timestamp >= cutoff, drops older.

Result 1 — receiver only got logs in the window ✅

Across all received records (journal + 35 infra container files; excluded the receiver's own self-feedback file):

┌───────────────────────────┬───────────────────────────────────────────┐
│          Metric           │                   Value                   │
├───────────────────────────┼───────────────────────────────────────────┤
│ records received          │ 2,790                                     │
├───────────────────────────┼───────────────────────────────────────────┤
│ min timestamp             │ 2026-09-22T18:51:23.02Z (1s after cutoff) │
├───────────────────────────┼───────────────────────────────────────────┤
│ max timestamp             │ 2026-09-22T18:59:00.55Z                   │
├───────────────────────────┼───────────────────────────────────────────┤
│ records older than cutoff │ 0                                         │
└───────────────────────────┴───────────────────────────────────────────┘

Nothing older than 18:51:22Z reached the receiver.

Result 2 — metrics identify dropped logs ✅

Queried in-cluster Prometheus for vector_component_discarded_events_total{component_id="pipeline_infra_drop_older_than_5m_1"}:

┌───────────────┬─────────────────────┬───────────────┐
│     Node      │ Discarded (dropped) │ Sent (passed) │
├───────────────┼─────────────────────┼───────────────┤
│ ip-10-0-1-15  │ 29,513              │ —             │
├───────────────┼─────────────────────┼───────────────┤
│ ip-10-0-1-192 │ 33,888              │ —             │
├───────────────┼─────────────────────┼───────────────┤
│ total         │ 63,401 dropped      │ 18,420 sent   │
└───────────────┴─────────────────────┴───────────────┘

The drop filter dropped ~63k historical logs (older than the cutoff) and forwarded ~18k in-window logs, matching the receiver evidence.
