seasonal detector breaks after business switches to four day work week error

Not specified by the original author.

TL;DR

Fix this in the seasonal detector by acting on the exact message first: rebuild the seasonal profile around the new four day pattern, retrain on post change data only, and keep the old profile for historical backtests. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

seasonal detector breaks after business switches to four day work week error

Use this when

• The operation in the seasonal detector fails with this exact message: seasonal detector breaks after business switches to four day work week error.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the seasonal detector, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: rebuild the seasonal profile around the new four day pattern, retrain on post change data only, and keep the old profile for historical backtests. Verify: weekend and off day alerts settle and a real off pattern spike still fires.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in the seasonal detector on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts, decisions or alerts against the source in the seasonal detector so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

The seasonal profile still expects a five day rhythm; every short week now looks anomalous against the old calendar.

TL;DR

Fix this in the anomaly detector settings by acting on the exact message first: derive the seasonal period from the sampling interval, twenty four for an hourly series with a daily cycle, read the period from the detector config before each run, and flag any value that contradicts the interval. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

Apply the specific fix for this error: derive the seasonal period from the sampling interval, twenty four for an hourly series with a daily cycle, read the period from the detector config before each run, and flag any value that contradicts the interval. Verify: the detector uses the interval correct period and daily patterns stop misfiring.

Why it happens

A period of seven suits daily data with a weekly cycle; on hourly data it aligns the series against the wrong rhythm and every day looks anomalous.

TL;DR

Fix this in the anomaly detector by acting on the exact message first: add the missing calendar effects explicitly: weekly seasonality, holiday list for the metric country, and an exclusion or special baseline for known peak days. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

anomaly detector misfires error seasonality not accounted for in baseline

Use this when

• The operation in the anomaly detector fails with this exact message: anomaly detector misfires error seasonality not accounted for in baseline.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

2. Apply the specific fix for this error: add the missing calendar effects explicitly: weekly seasonality, holiday list for the metric country, and an exclusion or special baseline for known peak days. Verify: backtest on the last occurrence of the same weekday or holiday and confirm no alert fires.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in the anomaly detector on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.

Why it happens

A baseline built from ordinary days cannot describe calendar driven days; the detector compares a holiday or Monday peak against a normal day and calls the difference an anomaly.
