If a data hole is detected while importing the time-series data into the Analyzer detail view database through the Database API or Data Importer, the importer considers the data hole as a valid nonviolated (green) value when evaluating the time-series data.
Example:
- Alert definition criteria = 2/5 (2 violations in 5 minutes)
- Alert definition threshold = greater than 10
- Inserted time-series data = 15, 20, null, null, null, null, 40, 50
- Data interval = 1 minute
- Data start time = 10:10 (HH:MM)
In the above scenario, violations are reported at time stamp = 10:11, 10:12, 10:13, 10:14, 10:17.
Even though 10:12, 10:13, 10:14, and 10:15 are a data hole, they are considered during alert evaluation as nonviolating values.
State changes are reported at = 10:11 (Green --> Red), 10:15 (Red --> Green), and 10:17 (Green --> Red).
