Overriding forces a fixed level across all alerts from that detector. *** ## Cron Schedule Controls how frequently a detector evaluates. Three formats are accepted: Plain-language intervals — easiest to read and configure. ``` 10 min 1 day 2 hours 30 seconds ``` Full [Quartz cron](https://www.quartz-scheduler.org/documentation/quartz-2.3.0/tutorials/crontrigger.html) expression syntax for precise scheduling. ``` 0 0 12 * * ? every day at noon 0 0/5 * * * ? every 5 minutes 0 0 0 ? * MON-FRI weekdays at midnight ``` Raw millisecond interval — useful for programmatic configuration via the API. ``` 60000 1 minute 3600000 1 hour 86400000 1 day ``` *** ## Condition (Threshold) Conditions control when a detector fires based on a numeric value. The syntax supports basic comparisons, percentage changes, delta operations, and edge-detection operators. Standard numeric comparison against a fixed value. ``` = 100 fires when value equals 100 != 100 fires when value does not equal 100 > 50 fires when |value| > 50 < 25 fires when |value| < 25 >= 35 fires when |value| >= 35 <= 50 fires when |value| <= 50 ``` Operators `>`, `<`, `>=`, `<=` apply **absolute value handling** by default. Prefix with `+` or `-` to compare exact signed values instead. Prefix the threshold with `+` or `-` to skip absolute value handling and compare the exact signed value. ``` > +10 fires when value > 10 (exact, positive only) > -15 fires when value > -15 < +30 fires when value < 30 < -20 fires when value < -20 ``` Fires based on the percentage change from the previous value. Formula: `(v - v₀) / v₀ × 100`. ``` > 25% change > 25% < 10% change < 10% >= 50% change >= 50% = 100% exact 100% change ``` **Example:** if `v₀ = 1000` and `v = 700`, the change is `-30%`. Fires based on the absolute change from the previous value using `++` (increase) or `--` (decrease). ``` > ++100 increase greater than 100 < --50 decrease greater than 50 >= ++30 increase of at least 30 = ++20 increase of exactly 20 ``` `>>` and `<<` variants fire **only once** when a condition transitions from false to true. Subsequent evaluations return false even if the condition remains true — useful for detecting threshold crossings without repeated alerts. ``` >> 10 fires once when value crosses above 10 << 25 fires once when value crosses below 25 >>= 10 fires once when value reaches or exceeds 10 <<= 25 fires once when value reaches or falls below 25 >> ++100 fires once when increase crosses 100 >> 25% fires once when percentage change crosses 25% ``` `>>>` and `<<<` variants fire only when a **new all-time maximum or minimum** is reached above/below the threshold. ``` >>> 100 new maximum above 100 <<< 50 new minimum below 50 >>>= 100 new maximum at or above 100 <<<= 50 new minimum at or below 50 ``` **Example for `>>> 100`:** | Value | Fires? | Reason | | ----- | ------ | -------------------------------------- | | 90 | No | Below threshold | | 200 | Yes | First value exceeding 100 | | 150 | No | Above 100 but below previous max (200) | | 300 | Yes | New maximum | | 200 | No | Below current max (300) | Spaces in condition expressions are ignored — `> ++ 100` and `>++100` are equivalent.
