Only one index family stops matching time-based detections after transform fixes.
An Elastic transform is corrected and one rule still misses hits because the timezone script uses the retired alias for one index family
The rule is right, but one transform still rewrites timestamps using the old timezone alias for a subset of events.
Scenario
What to check first
- Identify the primary failure signal in the Incident Response scenario.
- Separate visible symptoms from the underlying technical dependency.
- Describe the safest recovery path and the follow-up prevention work.
Checking checklist
- Summarize the current impact and the last known change.
- Collect direct evidence from logs, runtime state, and configuration before changing anything.
- Separate immediate recovery from permanent prevention work.
Recovery and prevention
Inspect timezone alias mapping before changing the rule window.
Questions worth viewing together
No. Keep commands, logs, file names, APIs, and product names unchanged, then explain the reasoning in the selected UI language.
State the root cause, the evidence that supports it, and the safest recovery direction.
The source scenario is treated as an incident artifact. Guidance, checklist, hints, and explanations can be localized around it.
