Data Monitoring
An alert appears late even though indexing is responsive. Compare event _time with _indextime for a bounded sample and inspect the producer clock.

Events from one source appear at an implausible date. Inspect raw timestamp text, sourcetype parsing settings and the affected host time zone.

Stack traces become separate events and inflate error counts. Compare raw log boundaries with indexed events from one known exception.

A new source arrives but expected extracted fields are absent. Inspect source, sourcetype and raw events rather than assuming ingestion failure.

A dashboard reports no events despite healthy forwarding. Run a narrowly bounded search in the intended index and confirm the user's index access.

Data Monitoring
One host stops appearing while other hosts continue to send logs. Correlate forwarder service state, output connectivity and receiver-side evidence for that host.

Daily event counts fall but the service is also receiving less traffic. Compare ingested volume with independent request or transaction counts for the same period.

The same event appears from two forwarding routes. Compare stable source event identifiers, host metadata and forwarding topology.

A log format change turns numeric durations into missing values. Compare old and new raw formats and measure the extraction success rate.

A threshold comparison behaves unexpectedly with text-form numbers. Inspect numeric conversion success and unexpected suffixes or separators in the source field.

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

A scheduled search misses records delivered after their event-time window. Measure ingestion delay distribution and compare it with the scheduled search lookback.
