Splunk: Missing host coverage
A total event count looks normal although a critical host is absent. Compare distinct reporting hosts with an inventory of expected active hosts.

Splunk: Late-arriving events in windows
A scheduled search misses records delivered after their event-time window. Measure ingestion delay distribution and compare it with the scheduled search lookback.

Splunk: Search selectivity
A routine dashboard scans all indexes for a rare service. Compare scanned event volume and job duration after adding the correct index, sourcetype and time constraints.

Splunk: Stats versus raw event inspection
An aggregate count hides a small group of malformed events. Compare summary results with a bounded sample of contributing raw events.

Splunk: Timechart bucket interpretation
A short error spike disappears in coarse dashboard intervals. Compare the same period at several bucket sizes and label incomplete edge buckets.

Splunk: Null grouping fields
A report undercounts records because some events lack a grouping key. Measure key presence before aggregation and inspect malformed source records.

Splunk: Lookup freshness
An ownership lookup routes new services to the wrong team. Compare lookup update time and key coverage with the service inventory.

Splunk: JSON payload extraction
Nested application data is indexed but a dashboard reads the wrong field path. Inspect sample payload structure and distinguish arrays from scalar objects.
