By default, the table contains all anomalies that have a severity of "warning"
or higher in the selected section of the timeline. If you are only interested in
critical anomalies, for example, you can change the severity threshold for this
table.
The anomalies table also automatically calculates an interval for the data in
the table. If the time difference between the earliest and latest records in the
table is less than two days, the data is aggregated by hour to show the details
of the highest severity anomaly for each detector. Otherwise, it is
aggregated by day. You can change the interval for the table, for example, to
show all anomalies.
